Full textAbstract:
The spread rates of alien species of Amphipoda and Mysida were calculated for the Dnieper, Pripyat and Neman rivers in the territory of Belarus. The maximal values of spread rate were obtained for Dikerogammarus villosus (in the Pripyat River - 37.8 km/year, in the Dnieper River - 17 km/year) and Dikerogammarus haemobaphes (in the Pripyat River - 53.6 km/year, in the Dnieper River - 17 km/year), while the minimal values of spread rate were calculated for mysids Paramysis lacustris (in the Dnieper River - 0.4 km/year) and Limnomysis benedeni (in the Dnieper River - 0.6 km/year), also for amphipods Chelicorophium robustum (in the Dnieper River - 0.5 km/year) and Echinogammarus trichiatus (in the Dnieper River - 1.3 km/year). The differences in the spread rates of species connected with the time of their first records at the monitoring points and the intensity of economic activities in the studied rivers.

The aim of the study was to establish the territorial patterns of the distribution of reservoirs in administrative regions and river basin districts, to identify the role of large, medium and small reservoirs in the balance of river flow regulation in Ukraine. In Ukraine, there are only 1054 reservoirs, among which there are six large reservoirs of the Dnieper cascade and the Dniester reservoir, and all the remaining 99.3% (1047 reservoirs) belong to the middle (M), small (S) and very small (VS) categories. For convenience, we call this group with the abbreviation MSVS-reservoirs. All reservoirs have a total volume of 55.13 km3. Thus, reservoirs regulate 32% of the total river flow of the country, amounting to 170.3 km3 per year. There are two main patterns of territorial distribution of reservoirs: large reservoirs are located on large rivers (Dnieper and Dniester) and are of national importance; MSVS-reservoirs – were created to provide water to industrial regions (for example, Donetsk, Kharkiv) and have regional or local significance. In terms of the volume of accumulated water, Ukraine is a country of large reservoirs. The six reservoirs of the Dnieper cascade contain 79% of the water, in the Dniester – 6%, in the MSVS-reservoirs – 15%. The volume of reservoirs in the Dnieper cascade is 43.71 km3, which is 82% of the average long-term runoff of the Dnieper (53.5 km3 per year). The operation of the Dniester reservoir (3.0 km3), which was created in the transboundary city of Dniester (Ukraine – Moldova), is carried out taking into account the water management interests of the two countries. MSVS-reservoirs are unevenly distributed over the territory of Ukraine. The largest number of them is concentrated in the arid central and southeastern regions of Ukraine, 45% of the total number of MSVS-reservoirs is located in the region of the river basin Dnieper. The largest total values of the total volume and area of MSVS-reservoirs is in the Odesa region due to the Danube lakes, which have been granted the status of reservoirs. In the use of territorial communities in Ukraine, there are 72% of the MSVS-reservoirs, 28% – leased. Among the regions of Ukraine, most of all are rented MSVS-reservoirs in the Transcarpathian region – 78%. In the Zaporizhye region, 56% of the MSVS-reservoirs are leased, in the Ternopil region – 54%. There are leases of MSVS-reservoirs in Ivano-Frankivsk and Lviv regions. Low values of the lease indicator were in the Autonomous Republic of Crimea (4%), in Kherson (7%), Vinnitsa (8%) and Volyn regions (10% each). Among the regions of river basins, there are more leased MSVS-reservoirs in the regions of the river basins. Southern Bug – 35%, Dnieper – 32%. The minimum rental rate was in the region of the Crimean river basin (4%). There is a lease of MSVS-reservoirs in the area of the river basin. Vistula.

Full textAbstract:
The monitoring results of organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) in Ukranian and world surface river waters were summarized. Total concentrations of OCPs, PCBs and PAHs in surface waters of Ukrainian rivers (Dnieper and Dniester) were 1.4–17.1; 2.8–57.2; 7.5–378.6 ng/dm3 , respectively. These pollution levels are medium on a global scale. Higher concentrations were recorded in the surface water of China, India and other Asian countries. Distribution of these organic ecotoxicants between water and suspended particulate matter (dispersionphase distribution) was analyzed and it was shown that in the majority of river waters ≥50% of them are associated with suspended particles. By the case of River Dnieper antibate correlations between watersoluble parts of individual OCPs, PCBs and PAHs and coefficient of their hydrophobicity were recorded. These correlations were presented graphically. In addition, relevant correlation coefficients and criterions of probability were calculated. The clearest correlation was established for PCBs.

The article presents the history of research of the left tributaries of the Middle Dnieper. The periodization of research by chronological periods from the IV century is developed. B.C. until the end of the XVIII century. The periods and key stages of river research during the corresponding period are highlighted. The issues of description of the respective rivers in antiquity and the Middle Ages are covered, in particular the elements of the geographical position of their river systems, water regime, feeding conditions, economical use, elements of river valleys and the organic world of their basins. Chronicle data and original works of scientists and politicians of these time periods are processed. The issues of geographical position of the river network, number and names of rivers of the studied sub-basin of the Middle Dnieper according to the maps of the XVI-XVIII centuries are covered in detail. Cartographic works of cartographers from France, the Netherlands, Italy, and Muscovy have been studied. Particular attention is paid to the cartographic works of the French cartographer Guillaume Levasser de Beauplan, who began a new stage in the mapping of the main left tributaries of the Middle Dnieper and their smaller tributaries. For the first time, 137 rivers of the Left Bank of the Middle Dnieper were marked on his maps. He put forward the theory of the formation of the channels of the left tributaries of the Middle Dnieper. On the maps of 1680 – 1760, we notice the beginning of the stage of stagnation in the image of the hydrographic grid of the left tributaries of the Middle Dnieper. The information according to the descriptive data of the Left Bank of Ukraine of the end of the XVIII century is singled out. The first detailed descriptions of the rivers – Kyiv, Chernihiv, Kharkiv governorates and Little Russia Governorate in the period from 1775 to 1800 were developed. A complete catalog of rivers of the I, II, III and IV order of the Middle Dnieper sub-basin according to descriptive data within the river basins with indication of their length is given.

Full textAbstract:
A survey study of the general hydroecological status of the historical small rivers of the same name Lybed and Pochayna, known since the Middle Ages (10th-11th centuries) in the Dnieper basin in Ukraine and in the Volga basin in the Russian Federation (RF), has been carried out. These rivers, many centuries ago, were natural objects around which cities formed, and in our time they turned out to be “absorbed” by cities. The state of six small rivers was analyzed: Lybed and Pochayna – tributaries of the Dnieper, Kiev, Ukraine; Lybed and Pochayna – Klyazma tributaries (Volga basin), Vladimir, Russia; Lybed – a tributary of the Oka (Volga basin), Ryazan, Russia; Pochayna – a tributary of the Volga, Nizhny Novgorod, Russia. According to hydromorphological indicators of the state of the rivers (catchment area and water content), the studied ones relate to rivers of very small size and very low water content. A significant part of the channel of these rivers is enclosed in a reservoir (41-100%). The hydroecological condition of these rivers is unsatisfactory, water is prone to pollution. The Pochaina River – a tributary of the Dnieper in Kiev (Ukraine) and the Pochaina River – a tributary of the Volga in Nizhny Novgorod (RF) turned into lost natural heritage sites. Given the involvement in urban infrastructure, the morphometric parameters of the six rivers considered are the greatest prerequisites for being more or less revitalized in the river Lybed – the right tributary of the Dnieper in Kiev (Ukraine).

Full textAbstract:
Abstract Lower reaches of largest Ukrainian rivers are zones of migrations for exotic euryhaline decapods. During 2000s new records of invasions of three euryhaline exotic decapods, Rhithropanopeus harrisii (Gould, 1841), Eriocheir sinensis Milne-Edwards, 1853 and Macrobrachium nipponense (De Haan, 1849), were made in the channels of Ukrainian rivers. Chinese mitten crab, E. sinensis, spread in the Danube Delta and reservoirs of the Dnieper River; Rh. harrisii - in the channels of the Danube, Dnieper, Southern Bug and small river Gruzskij Yelanchik in the Azov Sea Basin; M. nipponense that was introduced in the Kuchurgan Liman (cooler reservoir of the Moldavian Hydro-power Station) - in the Dniester Delta. The migration zone of the established population can cover significant part of river watershed; it is necessary to take this fact into account at an estimation of biological invasion risk. Main problem in the investigation of exotic decapods in Ukrainian waters is absence of specialized methods used in the standard ecological monitoring. Among euryhaline exotic decapods, only Rh. harrisii is sometimes sampled with the equipment used in the monitoring of macrozoobenthos. A few records of these species at the large extent of their supposed ways of migration are the result of gaps in the study of their distribution in Ukrainian inland waters. Realistic attitude toward this fact is very important for the estimation of invasions in the inland waters of this region.

According to the assessment made in the article, the current data on the number of water bodies on the territory of Ukraine are: 63119 rivers; about 20 thousand lakes; 1054 reservoirs; 50793 ponds. There are rivers in Ukraine: large (> 50 thousand km2) – 8 rivers: Dnieper, Dniester, Danube, Desna, Pripyat, Southern Bug, Seversky Donets, Tisa; medium (2.0-50 thousand km2) – 82 rivers; small (<2.0 thousand km2) – 63,029 rivers (99.87%). There are lakes in Ukraine: very large (> 100 km2) – 1 lake: Yalpug; large (10-100 km2) – 21 lakes; medium (1-10 km2) – about 70; small (0.5-1.0 km2) and very small (<0.5 km2) - all other lakes (99.54%). There are reservoirs in Ukraine: very large (10-50 km3) – 2 reservoirs: Kremenchug and Kakhovskoe – on the river.Dnipro (0.2%); large (1.0-10 km3) – 5 reservoirs; Kievskoe,Kanevskoe, Kamenskoe, Dneprovskoe (on the Dnieper river), Dnestrovsky – on the Dniester (0.5%); medium (0.1-1.0 km3) – 11 reservoirs (1.0%); small (0.01-0.1 km3) – 88 reservoirs (8.4%); small (<0.01 km3) – 948 reservoirs (89.9%). There are ponds in Ukraine: very large (> 500 thousand m3) and large (200-500 thousand m3) – 13%; medium (50-200 thousand m3) – 29%; small (10-50 thousand m3) and very small (<10 thousand m3) - 58%. Of great importance was the approval by the Verkhovna Rada of Ukraine in 2016 of the hydrographic zoning of the territory of Ukraine with the allocation of 9 regions of river basins: the Dnieper, Dniester, Danube, Southern Bug, Don, Vistula, Crimean rivers Black Sea rivers, Azov rivers. Almost all rivers of Ukraine belong to the basin of the Black and Azov seas. In addition to the area of the river basin Vistula (Western Bug and San rivers) which belongs to the Baltic Sea basin and occupies only 2.5% of the country's territory. It is shown that since hydrographic studies in Ukraine were carried out more than 50 years ago, modern hydrographic surveys of the country’s territory with the creation of a modern water cadastre and the establishment of real morphometric parameters of water bodies (rivers, lakes, reservoirs, ponds) are necessary. The main organizations dealing with these issues are the State Agency for Water Resources of Ukraine and the Ukrainian Hydrometeorological Center of the State Service of Ukraine for Emergency Situations. It is also necessary to regulate a number of concepts that are used a priori, but do not have a definition, clear parameters (for example, a stream, a source, a digging pond, etc.). This is difficult to implement through the Water Code of Ukraine or state standards, but it can be easier to do through the officially approved methods in which these terms are used.

This article is devoted to the typology of lakes of the North-Steppe Dnieper. In developing the typology of lakes, the parameters were taken into account: landscape location, hydro-chemical and hydro-biological characteristics and the degree of their anthropogenic transformation. The data presented are based on the processing of stationary and route research materials from 1998 to 2018 on the lakes of river valleys: Dnieper, Samara, and Orel. Hydrological indicators are analyzed according to the literature, cartographic and archival data of the Dneprodiprovodkhoz Institute and the Biology Research Institute of Oles Honchar Dnipropetrovsk National University. Floristic studies were carried out using general botanical methods of collection and herbarization, and in the study of typical aquatic flora - special hydro-botanical methods. Geo-botanical studies were carried out according to geo-botanical and special hydro-botanical methods. The article presents the hydrological and hydro-botanical features of the lakes of the valley of a large river (Dnieper) and medium rivers (Samara, Orel). Lakes are located exclusively in valley-terrace landscapes in the northern part of the steppe zone of Ukraine. Despite this, based on cartographic materials, we proposed zoning of the territory of the lakes of the North-Steppe Dnieper according to the criteria: their location in lake regions, in various landscapes and the degree of anthropogenic transformation. The following districts and subareas were identified: Dnieper Lake District (Dnieper floodplain lake subarea with slight flooding of the floodplain, Dnieper Lake subarea of floodplain terraces, Dievsky floodplain lake subarea); Samara Lake District (Lake Subarea of Samara Coniferous forest, Lake Subarea of Estuary part of Samara); Orel Lake District. Lakes are located in various physical and geographical conditions of the floodplain, arena and third saline terrace. The typology of the lakes of the North-Steppe Dnieper basin was developed on the basis of regionalization of the location of the lakes, distribution according to the ecological and topographic profile, hydrological, hydro-chemical regimes, degree and nature of overgrowing. 11 types of lakes are identified based on the above criteria. 6 types were identified for the valley of a large river: floodplain lakes (3 types) with a long-flow regime, lakes of the second (sandy) terrace (2 types) and highly mineralized lakes of the third (saline) terrace. 5 types were identified for the valleys of middle rivers: floodplain lakes (3 types) with an episodic short-burial regime, lakes of the second (sandy) terrace (low-mineralized) and excessively mineralized lakes of the third (saline) terrace.

The paper presents analysis of general (GА, Px, ΔЕ, ml∙sec) and specific (SA, Px, ΔЕ, mg∙sec) of oxidoreductase enzyme activity (Peroxidase, Px, EC 1.11.1.7), which together with Catalase (Cat, EC 1.11.1.6) forms a double link antioxidant protection of cells in the organisms of different levels of organization (non-specific response to stress) in the conditions of increasing redox processes under the exogenous stress. These markers of changeable environmental factors were sampled in the leaves of Salix alba L., which grew along Mokra Sura River (anthropogenically polluted with high level of salinity, experiment) and Shpakova River (without anthropogenic impact, control). These rivers belong to the basin of the Dnieper River (Steppe Dnieper region) that has high industrial load. We used plant growth regulator "Kornevin" in order to accelerate the rooting and reduce the exogenous pressures on the plants. We detected nonspecific reaction towards peroxidase in anthropogenic pressure conditions and determined significant differences between experiment and control regards antioxidant protection depending on growth and development conditions.

The changes in the ecological state of the water of the Dnieper basin have been analyzed and the possible causes of this phenomenon and the possible ways to improve its ecological status have been identified. Methodology. The analysis was performed taking into account changes in the content of the normalized parameters: sums of anions; dissolved oxygen in water; biochemical oxygen consumption; phosphates, nitrites, nitrates, as well as ammonium. The assessment was carried out using a retrospective analysis of the monitoring data and environmental assessment of Ukraine's water resources by the State Water Resources Agency of Ukraine over the past 10 years. A retrospective analysis was conducted according to the data on the control of water intake on the Dnieper within the Basin Water Resources Management at 14 posts. The analysis was carried out taking into account the requirements of the State Standard of Ukraine 4808: 2007. Results. In the future, changing the ecological status of the surface waters of the Dnieper basin in the direction of its improvement cannot happen without the development and implementation of a reliable and effective model for predicting its ecological status. The solution to the complex problem of environmental rehabilitation of the Dnieper basin should be taken to a new level in accordance with fundamental changes in the nature management and economic development strategy of the country and only through the development of a national program of restoration of its ecological status. To date, the only possible solution to the problem of deterioration of the Dnieper's environmental status may be to create effective levers for managing the Basin Directorate, including by improving the methodological basis of its environmental monitoring system. Originality. The study is based on an integrated approach, which includes conducting a retrospective analysis of all available data in the State Agency for Water Resources of Ukraine, which takes into account the principles of biodiversity conservation, sustainable use of water resources, management and river basins, monitoring and evaluation of information on their status. Practical value. The results of the study can be used in the development and implementation of a reliable and effective model for predicting the ecological status of surface waters of the Dnieper basin.

Full textAbstract:
This publication presents the analysis of the mostly used international and Ukrainian classification systems for wetland areas performed for identification of different-type marsh biotopes of steppe rivers in the Northwest Black Sea Region. Among the classification systems, the most well-known are the Ramsar Classification System for Wetland Type (1971) and Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al., 1979). In these systems, valley marsh biotopes are identified as riverine and palustrine, non-tidal, unstable (perennial impounded and seasonal/intermittent) freshwater marshes on mineral rich soils predominantly covered by grasslike plants (rush, reedmace, sedge). The delta marshes of the Danube, Dniester and Dnieper are referred to as tidal brackish and freshwater marshes. According to Ukrainian classification systems for hygromorphic geosystem, marsh biotopes are regarded as mouth wetlands, which is peculiar to delta marsh areas of the Danube and Dnieper interfluve. Thus, riverbed marshes of small and medium-sized rivers are located in other areas and are usually met both in the lower (continuous marsh areas), middle (fragmented marsh mosaic), and upper (coastland) river flow areas, which is caused by an unstable watercourse rate and transforming of their riverbed parts into marsh sections covered by eurytopic wetland species.

Stellate tabpole-goby Benthophilus stellatus (Sauvage, 1874) is one of 5 representatives of the goby family (Gobiidae) in Belarus, discovered in 2011 in the Dnieper River. Until now, this species within Belarus is practically haven’t been studied and is of interest for the study as a new species in the freshwater watercourses. Standard ichthyological methods of trapping and methods of processing the material have been used in the study. A total of 39 morphometric characteristics are investigated, however, the comparison with the specimens from the natural habitat was carried out by individual indicators using a two-sample t-test for independent samples (tst). The analysis of stellate tabpole-goby plastic characteristics from the Belarusian section of the Dnieper River is presented for a first time and the meristic characteristics data of the species on this section of the river is supplemented. There were significant differences on 3 meristic and 11 plastic features from the individuals of the stellate tabpole-goby from the Kakhovka reservoir (Ukraine, the lower reaches of the Dnieper River).

Full textAbstract:
The Dnieper river is one of the largest rivers in Europe. It is the fourth largest river in terms of basin area and length after the Volga, Danube and Ural, and the second largest of the rivers that flow into the Black sea, after the Danube. From the point of view of territorial distribution of water resources, the Dnieper basin can be divided into two zones. The first zone includes the Russian and Belarusian parts of the basin, which is a zone of river flow formation. It is characterized by an insufficiently high level of water resources use. The second zone, which is a part of the Ukrainian part of the river basin, is characterized by a small inflow of water from tributaries and a high level of water resources use. Rivers, watercourses of which run through the territory of two or more states, are called as transboundary. Different sections of the same river are used by different states, and the use of water resources and catchment area in the upper reaches of the river will affect the quantitative and qualitative parameters of water downstream. This means that the unified environmental system is divided by a state border and is managed in each individual state at its discretion. This affects the river and surrounding areas. After the collapse of the Soviet Union, the problem of transboundary water bodies became very relevant for Russia. Neighboring countries have faced a number of environmental problems in border territories and transboundary river basins, where environmental problems have persisted and often worsened, but the institutional framework for their effective solution has been lost

Based on the data of the expedition carried out in August 2012, the features of the structure of the salinity and fDOM concentration fields, as well as the correlation between these values in the Dnieper-Bug estuary, are analyzed. It is shown that the salinity field in the Dnieper-Bug estuary is characterized by all structural features typical of coastal sea areas freshened by river runoff, while the fDOM concentration field has anomalous properties due to the presence of an anthropogenic component of this value. The presence of fDOM of anthropogenic origin is most significant in the western part of the Dnieper estuary and is related to the influence of the city and port of Ochakov. The maximum content of fDOM was recorded here, which caused an anomalous horizontal distribution of this substance concentration, increasing from the mouth of the Dnieper to the open Black Sea waters. The contaminated areas of the studied water areas, which are adjacent to settlements and occupy the predominant part of the water surface of the Dnieper-Bug estuary, are characterized by an increased fDOM content and intrusive feature of the vertical structure of this substance concentration field of. It is revealed that in the Dnieper-Bug estuary there is no inverse correlation between the salinity fields and fDOM concentration, which is typical for unpolluted coastal waters, freshened by river runoff. A similar anomaly is an indicator of the pollution of coastal waters with organic matter.

Full textAbstract:
The article shows the fallacy of traditional ideas about the existence of a water transit route from the Baltic to the Volga and the Dnieper. Due to the low water content of the rivers of Eastern Europe during the water minimum of the first Millennium ad and the presence of rapids on the Volkhov, Msta and Lovat, these rivers were unsuitable for navigation, not only for keel Scandinavian, but also for any cargo ships. The water road from Ilmen to the Volga, as well as the Dnieper (the way «from the Varangians to the Greeks») never existed. The hydrographic characteristics of Msta and Lovat exclude the possibility of platoon movement of rowing vessels along these rivers. Shipping conditions along the Western Dvina and the Dnieper were extremely difficult.

Unisexual forms of lower vertebrates (fish, amphibians, and reptiles) reproduced by parthenogenesis, gynogenesis, or hybridogenesis are represented by diploids, triploids, or tetraploids, whose origin is associated with interspecific hybridization. Among fish species, the highest variability of unisexual polyploids was found in the genus Cobitis. The structure of their genomes and putative parental species holds great interest for the investigation in association with questions about possible evolutionary success. In particular, it serves to elucidate the possible high colonization properties of a few polyploid forms, in contrast to the local history of rather numerous hybrid forms with a limited distribution. Therefore, the aim of this study was to describe the karyotype structure of two newly discovered triploid forms of the genus Cobitis, to analyze their origin and putative parental species. The karyotype structure of 182 spined loach individuals from the Western Dvina River and 91 individuals from the upper Dnieper River of the Smolensk District of Russia was studied. A total of 121 studied individuals from the Western Dvina comprised triploid females with a chromosome number 74 and karyotype consisting of 13 meta-, 39 submeta-, and 22 subtelo-acrocentric chromosomes. Among loaches collected in the upper Dnieper River, 42 triploid females were found with 74 chromosome number including 23 meta-, 26 submeta-, and 25 subtelo-acrocentric chromosomes. Other individuals from both localities were karyologically identified as Cobitis taenia Linnaeus, 1758 with 2n = 48. The triploid form of spined loaches of the Western Dvina River most likely arose as a result of the hybridization of Cobitis tanaitica Bǎcescu et Mayer, 1969 and C. taenia. The range of C. tanaitica, whose karyotype is characterized by an evolutionarily fixed Y-autosomal translocation, is limited to the rivers of the northern coast of the Black Sea. Therefore, hybridization probably happened in late Pleistocene in the Dnieper River system, where both parental species occur. The triploid form that arose here is unique for the Baltic Sea basin. Probably, it colonized the Western Dvina through the artificial Berezinskaya water system (Berezina Canal = Daugava–Dnieper Canal), but at the same time it was forced out of its area of origin by other triploid forms which are now widespread there. According to the karyotype structure, the triploid form, common for both the upper and lower reaches of the Dnieper, has a trihybrid origin, with probable hybridization of Cobitis elongatoides Bǎcescu et Mayer, 1969, C. tanaitica, and yet unidentified species Cobitis sp. Both studied triploid forms are parts of unisexual-bisexual complexes, in which their putative diploid maternal species (C. tanaitica and C. elongatoides) are absent, and the role of the host species involved in reproduction belongs to C. taenia.

At the present stage, in the conditions of growing scale of anthropogenic impact on water resources, shortage of quality drinking water and climate change, priority measures should be their rational use and comprehensive conservation. The article analyzes the environmental problems of surface waters of river basins, analyzed the existing potential of water resources and the state of water use, qualitative and quantitative indicators of surface waters of river basins of the Dnieper, Southern Bug and Dniester within Khmelnytsky region. The main problems of water resources of the region are highlighted and proposals for their effective use are formulated. A feature of the Khmelnytsky region is its location in three river basins – the rivers Dniester, Southern Bug and Dnieper. The main share of water intake in the region comes from surface objects, and s unevenly distributed throughout its territory. The study shows that in the sectoral structure of general use of water in Khmelnytsky region, the largest consumer is industry (58.6 %), and among industries electricity sector is the main and largest consumer. The main environmental problem of the region is the pollution of surface water bodies with untreated and insufficiently treated return water. In the territory of Khmelnytsky region, 80 water users discharge return water into water bodies. The average annual concentrations of manganese (2–6 times), copper (4–7 times) and nitrites (2–5 times) were exceeded in all control samples from water bodies of Khmelnytsky region. There is also an increase in the total amount of discharges of pollutants, including petroleum products, suspended solids, sulfates, total iron, and copper. In addition to pollution, the problem is the current structure of land within river basins. Excessive plowing is one of the main negative factors that contributes to the deterioration of the water regime and leads to pollution of water bodies. Within the Khmelnytsky region, arable land is the dominant form of land use, their share is 50–70 %. Restoration of the quality of water bodies involves the implementation of measures to reduce the environmental risk of deterioration based on the analysis of the impact of anthropogenic factors and a set of water protection measures.

AbstractInformation about the morphology and alluvial sediments of the Dnieper Valley is reviewed. The Dnieper Valley originated in the Late Miocene. The Middle Dnieper Valley is an intercontinental alluvial basin and the Lower Dnieper Valley is a shallow canyon that ends with a delta. Identification of the alluvial dynamic facies (channel, overbank, abandoned channel) is crucial for stratigraphical analysis. The dynamic facies form regular sequences - alluvial suites that combine into series. Individual suites and series are characterized by their mode of occurrence, facies composition, lithological features and expression in the modern landscape. Their stratigraphie position is established with reference to index beds and palaeontological, geochrono-logical and archaeological research, allowing them to be correlated along the valley. Correlation between different parts of the Dnieper system uses a combination of facies and geomorphological analyses, whereas correlation with other river systems makes use of mammalian and molluscan biostratigraphy. Global events (marine regressions and glaciations) that brought about similar reactions in different fluvial systems can be also used for correlation.

Full textAbstract:
In December 2016, the common perсarina Percarina demidoffii Nordmann, 1840 has been evidentiary detected in the Dniprovske (Zaporizske) reservoir for the first time. Two specimens of percarina were caught in the rowing channel area (the upper part of the reservoir) near the Dnipro city. One individual was caught there in 2017 as well. The paper presents their morphological characteristics, as well as a comparison with specimens from the brackish waters of the Dniester estuary (the Black Sea). The preliminary data allow us to assume that differences in some plastic characters may have adaptive character in relation to the environment. There are no any meristic differences between these fishes. It is noted that the new finding of this fish species in the cascade of Dniprovske reservoirs allows us consider P. demidoffii as not mesohaline but as a freshwater-oligohaline species. The finding of the common percarina in the Dniprovske reservoir confirms a few earlier published data about the advance of this fish upstream of the Dnieper River and extends its current range. The presence of P. demidoffii as a new species for the fish fauna of the Dniprovske reservoir shows a continued active advance of the Ponto-Caspian fish species upstream of the cascade of reservoirs on the Dnieper River.

The article analyzes the influence of the water artery – the Dnieper River and the active relief on the specifics of the city development on the example of Kyiv since ancient times. The specifics of the development of Kiev was that this development began from the territories close to the Dnieper, located on the right steep bank of the city. It is proved that initially the maximum use of proximity to the river and active Landforms was applied exclusively for religious dominants, whereas since the Soviet era, this vector has radically changed first towards representative ideological buildings, and in modern conditions – towards commercial multi-storey residential development. The purpose of the article was to trace how the waterway – the Dnieper River, accent landforms and landscaping influenced the formation of Kyiv during its existence, as well as to determine the features of the influence of these natural components on the modern development of the city. The scientific novelty of the study lies in a comprehensive coverage of the relationship between the natural components and development of Kyiv from ancient times to the present, identifying modern problems, their causes and ways to overcome them.

Full textAbstract:
The work presents a sequel of publication series on vegetation of the Dnieper River mouth region. The characteristic of syntaxonomical diversity of forest and shrub vegetation of the Dnieper River mouth area belonging to the Salicetea purpureae and Alnetea glutinosae classes are presented. There have been picked out 12 associations and 1 community attributed to 3 orders and 4 alliances. Salicetea purpureae class in the Dnieper River mouth is represented by communities formed under long time inundation conditions, along the sides of islands, arms of the main river-bed, lakes, and also along the sides of secondary arms with salty marsh or soddy sandy soils. These communities are more typical for river mouth habitats. The class includes the Salicetum albae, Saliceto-Populetum, Populetum nigro-albae, Fraxino-Populetum, Populetum marylandicae, Elaeagnetum angustifoliae, Amorpha fruticosa com., Salicetum triandrae aassociations. Mass expansion of com. Amorpha fruticosa was recorded in the Dnieper River Delta. Due to the high coenotic activities of this species the community spreads over the flood territories. To prevent Amorpha fruticosa invasions there have been induction of a long time and powerful spring water discharge from the reservoirs of the Dnieper’s cascade. Alnetea glutinosae class includes Salicetum cinereae, Thelypteridi-Salicetum cinereae, Urtico dioicae–Alnetum glutinosae, Carici acutiformis–Alnetum, Carici elatae–Alnetum glutinosae associations. The plant communities occur in the nature complexes of the river mouth at the offshore parts of islands under a long time inundation. Syntaxonomical analysis of phytocoenotic tables confirms the integration of Alnetea glutinosae and Franguletea classes as long as these communities occupy similar habitats (mire ecotopes with peaty-mire and mire soils) and they have a number of common diagnostic species. The coenotaxonomical and coenotical particularities of forest and shrub vegetation communities were revealed. In comparison with similar plant communities of the northern regions they do not take a big part in specific composition of boreal flora, but the role of species of the ancient Mediterranean origin is more remarkable. Considerable part of alnetal florocoenotic complex species is absent (Kuzmichev, 1992) or so-called alder forest historical suite (Zozulin, 1973), in particular, genus Sphagnum species. Other representatives of mire flora that are typical for mezotrophic and eutrophic mires of the forest zone are missing also. The forest stand structure is characterized by slight or absent understory, and in grass layer there are typical steppe and salt habitat species. As a result of significant human impact for the last ten years an expansion of mesophytes and xeromesophytes in the grass layer as well as adventitious and ruderal plant species was noticed. A change of coenoses of flood-forest vegetation under recreation by the communities of forest-park type takes place, and in depressions they are replaced by mire or salt meadows (Chinkina, 2003). It is necessary to underline the needs of ecology-sozological monitoring of their conditions and conservation of coenoses as well as the rare species population.

Full textAbstract:
The operation of the hydroelectric power plant is one of the main reasons for the transformation of river runoff. The change in the hydrological regime affects several other processes taking place in the river channel, including the transformation of its geomorphological features. The article presents the impact of the Kaniv and Włocławek dams on the hydrological regime of the middle Dnieper River and the lower Vistula River. The nature and magnitude of changes in the Dnieper and The Vistula rivers flow regime caused by the functioning of the dams were determined using IHA (Indicators of Hydrologic Alteration) and the RVA (The Range of Variability Approach) method. It was demonstrated that the operation of the hydroelectric power plant especially in the hydropeaking system is the cause of a large flow alteration in respect of the frequency and duration of low- and high-flow pulses and the rate and frequency of change in the flow. It was assessed how the change in flow conditions in connection with the deficit of sediments affected the transformation of the Vistula and Dnieper river channels downstream of the dams. Based on our results, the reaction of the fluvial system to changes in the flow regime caused by the operation of the Kaniv and Włocławek hydroelectric power plants consisted in: 1) changing the width and depth of channels; 2) changing the size of the forms separating channels; 3) fixation of the anastomosing fluvial system. More dynamic water flows due to the operation of hydroelectric power plants modify and dynamize the natural process of evolution of a fluvial system into an anastomosing system by causing the incision and narrowing of the main channels, because of which the side channels occupy a higher position above them. On the other hand, the equalization of the water flow in the channels causes a decrease in the water level and the disappearance of the flow in the side channels. As a result, the islands separated by these channels merge and inter-channel areas are formed.

Full textAbstract:
Crossbreeding experiments were used to estimate cryptic species in water bodies of Ukraine and Russia because the most useful criterion in species independence is reproductive isolation. The problem of cryptic species in the genus Eucyclops was examined using interpopulation crosses of populations collected from Baltic Sea basin (pond of Strelka river basin) and Black Sea basin (water-reservoires of Dnieper, Dniester and Danube rivers basins). The results of reciprocal crosses in Eucyclops serrulatus-group are shown that E. serrulatus from different populations but from water bodies belonging to the same river basin crossed each others successfully. The interpopulation crosses of E. serrulatus populations collected from different river basins (Dnipro, Danube and Dniester river basins) were sterile. In this group of experiments we assigned evidence of sterility to four categories: 1) incomplete copulation or absence of copulation; 2) nonviable eggs; 3) absence of egg membranes or egg sacs 4) empty egg membranes. These crossbreeding studies suggest the presence of cryptic species in the E. serrulatus inhabiting ecologically different populations in many parts of its range. The same crossbreeding experiments were carries out between Eucyclops serrulatus and morphological similar species – Eucyclops macruroides from Baltic and Black Sea basins. The reciprocal crossings between these two species were sterile. Thus taxonomic heterogeneity among species of genus Eucyclops lower in E. macruroides than in E. serrulatus. The interpopulation crosses of E. macruroides populations collected from distant part of range were fertile. These crossbreeding studies suggest that E. macruroides species complex was evaluated as more stable than E. serrulatus species complex.

The study presents materials on the status of aquatic biological resources and their habitat in the Dnieper River within the territory of the Russian and the Belarus. In the recent period, there has been hardly any complex fishery research in the upper reach of the river within the boundaries of the Smolensk Region due to the lack of commercial fishing; the same can be applied to the reach of the river within the Vitebsk Region in Belarus. The collection of materials and scientific and research accounting network surveys for monitoring the state of aquatic bioresources were carried out on the Dnieper River as part of the research in 2019 according to a preplanned grid of stations. When fishing for scientific research purposes, 20 net-stops of smooth frame nets were made in the Russian section, and 9 net-stops were made in the Belarusian section. In the Russian section of the Dnieper River, the species composition was 16 species of fish, and in the Belarusian section — 22 species. The main catch in the Russian section is roach 29% and chub 20%, in the Belarusian section bream — from 3 to 46%, roach — from 19 to 63% and gustera — from 1.8 to 33%, in a slightly smaller number of river perch (on average up to 10%). The share value of roach and guster tends to decrease from the upper to the lower areas, bream-on the contrary to increase, the value of perch is approximately equal in all areas. In the size structure of the caught fish species, there is a dynamic with a good reproductive potential.

Full textAbstract:
Dnieper Left-Bank Forest-Steppe region in the Early Iron Age was inhabited in several stages. For the first time, the agricultural population appears in the Zhabotyn period. Settlements that emerged at this time would become the centres of some settlement structures in the Early Scythian period. There are no burial sites of the settled population of Pre-Scythian times in the basin of Vorskla and Psel rivers. The few burials of nomads of Pre-Scythian time are synchronous to this group of settlements with ashhills. These assemblages, except Butenky, have no signs of militarization of the population of the Post-Zrubna culture, which have left in the Forest-Steppe. It’s likely that these two groups of populations coexisted peacefully, occupying separate ecological niches.
The development of this population in relatively calm military and political conditions could have caused a demographic explosion and we have developed settlement structure in the middle of 7th century BCE. It represented by «cluster» of settlements with ashhills, which was united by a single burial mound necropolis.
Today, it may be considered densely populated territory between Vorskla and Psel rivers with an agricultural population from the Dnieper Right-Bank region in the Early Scythian time. At that time, nomadic groups are emerging in the region, some of which participated in Asia Minor campaigns. Their burial monuments are mainly identified at the routes of their movement and places of frequent stops (winterings, etc.) — the Sula river region, north-western Vorskla river region (Kup’ievakha, Kolomak). The appearence of the settlement at the place of Western fortification of Bil’sk hillfort Western fortification also connected with the fact that exactly nomads probably chose this strategic place as a wintering at the intersection of communications roads. Thus, the ethnical and cultural history of the Dnieper Left-bank Forest-Steppe of that time connected with close interaction of Vorskla river’ farmers with different groups of Iranian-speaking nomads, which were the decisive force in the region and had control over the settled population.

Abstract This article presents the features of the phylogenetic organization of the plant communities of the Dnieper River terrace within the ‘Dnieper-Orilskiy’ Nature Reserve and the patterns of its spatial variation involving remote sensing data of the Earth’s surface. The research materials were collected in the period 2012−2016 from within the nature reserve. The research polygon is within the first terrace (arena) of the Dnieper valley. Sandy steppe, meadow, forest and marsh communities within the Protoch river floodplain and the Orlova ravine, as well as artificial pine plantations were the habitats present within the research polygon. The vegetation description was carried out on 10×10 m (100 m2) plots. A total of 94 geobotanical descriptions were made. Data on plant phylogeny was obtained by the Phylomatic service. Phylogenetic diversity of the communities was assessed by the Faith, Simpson and Shannon indices. Phylogenetic analysis was performed by means of a double principal coordinate analysis (DPCoA). The vegetation cover within the investigated polygon was represented by 189 species. Abundance Phylogenetic Deviation (APD) for the investigated metacommunity was evaluated to −0.53, which is statistically significantly different from random alternatives (p = 0.001). The APD negative value indicates that phylogenetic organization of the investigated metacommunity is overdispersed. The permutation procedure allowed us to establish that the eigenvalues of the DPCoA-axes obtained as a result of the real phylogenetic tree were significantly higher than their own number for the random phylogenetic trees for the first seven axes. This indicates that the first seven axes are useful for additional information on the ordination structure of the metacommunity.

This paper discusses the comparative chronology of Upper Paleolithic sites in the Middle Dnieper River basin, based on archaeological and radiocarbon evidence. Three chronological periods of the development of the Upper Paleolithic are distinguished in this area. According to the data obtained, the third period is similar to the European Magdalenian, yet its economies were different. The base of the subsistence economy for Dnieperian hunters was the procurement of mammoth, while reindeer was the most important for the subsistence of European Magdalenian. The abundance of mammoths and the raw material in the form of mammoth tusks made a deep impact on both the economy and material culture of the hunters in the Dnieper River basin. The 14C dates confirm the chronological subdivision.

Full textAbstract:
Creation of reservoirs by regulation of the Dnieper River and small rivers caused significant changes in the conditions of existence and affected on fish biodiversity of pondsof Prydniprovya. To the anthropogenic factors influencing the species composition of fish fauna factors of technical and fishery character can be included. Technical impact on water bodies is associated with the creation of new artificial lakes, ecosystems of which are not stable and are influenced by invasive processes. Fisheries management measures include work on the introduction of new species of fish that primarily have economic importance for the development of industrial fishing. Work on the introduction of new species have both positive and negative effects, but nevertheless new species affect natively on fish fauna. This transforms biota of reservoir and creates conditions for further spread of new species, increasing their numbers, creating new ecological relationships in the ecosystem of the pond. In the formation of the Dnieper (Zaporizhia) reservoir`s fish fauna it is traditionally defined five stages: the first stage is before building a dam to the Dnieper (until 1931) when there was a natural Dnieper rapids area, inhabited by migratory, semi-migratory and local fish; the second stage is the beginning of formation of reservoir`s fish fauna with the gradual disappearance of reophilic and dominance of limnophilic species (1931–1941); the third stage is the restoration of fish populations of Dnieper rapids due to destruction of dam during the Second World War (1941–1947); fourth stage is the secondary formation of ichtiocenosis of reservoir after recovery of dam (1947–1960); fifth stage is reforming of the structure of fish fauna in terms of cascade (creation of Dnieper reservoirs) and anthropogenic pressures (from 1961 to the present period). The first stage is defined by period of filling the reservoir. After the construction of Zaporozhye hydroelectric station the process of rebuilding fish fauna took place. In the early years of the reservoir existence migratory and semi-migratory fish have naturally disappeared. The species composition of fish fauna has decreased by 11 taxons. The number of reophilic species has markedly reduced and remained predominantly in the upper river part of the reservoir. The lower part of reservoir with sustained hydrological regime has been being actively assimilated by fish of limnophilic complex. The second and third stages are associated with the destruction of the dam during the Second World War and the short restoration of hydrobiological regime of Dnieper rapids, until the re-filling of the reservoir and its final transformation into a regulated pond. The flow of these two phases has not influenced significantly the structure of industrial ichtyocomplex total number of species at that time was 38 taxons. The fourth stage involves fishery exploitation of reservoir. With the aim of the purposeful impact on formation of industrial fish fauna of the Dnieper (Zaporizhia) reservoir, considering sufficient development of natural fodder the works on artificial introduction of new species were carried out in the years 1950-1960. The fifth stage of development and current state of fish fauna of reservoir is characterized by the emergence and spread of invasive species. During the period of existence of the Dnieper (Zaporizhia) reservoir ichthyofauna of the reservoir has substantially transformed. In the modern fish fauna of reservoir there are 52 species of fish which are representatives of 14 families. Compared with the period of existence of Dnieper River before its regulation the number of species remained at the same level, but the species composition and structure of fish fauna changed drastically due to the loss of some species and the emergence of other species, mostly unwanted invaders. Changing the number of species is related to several factors. Firstly, process of spread of species upstream took place after the disappearance of Dnieper Rapids and rise of mineralization. Secondly, with the deliberate introduction of fish with purpose of fishery exploitation of the reservoir, and as a consequence randomly invasion of some species that came from fish farms. Thirdly, emergence of new species is also connected with the deliberate release of fish to the open water, similarly Pumpkinseed Sunfish Lepomis gibbosus (Linnaeus, 1758) has appeared in the Dnipro (Zaporizhia) reservoir, which is well acclimatized and has broadly extended its habitat in reservoirs of Dnipropetrovsk region. Today about 31 % of fish species of Dnieper (Zaporizhia) reservoir is adventitious. The process of genesis of fish fauna of the Dnieper (Zaporizhia) reservoir is still ongoing and it is connected with the subsequent emergence of new species and rise of their numbers. Such changes in the fish fauna of reservoir can harm fisheries because the vast majority of fish aliens are competitors by food for young commercially valuable fish species.

The article analyzes the water quality of surface water bodies (on the example of rivers of the Dnieper basin) by the method of main components, identifies and interprets the main factors that form long-term variability of water quality of surface water bodies and make different contributions to the total variance. The research was carried out according to the samples of control water intake of the Dnieper River within the Basin Water Resources Management at 12 posts, for the period from 2011 to 2020. The leading factors were identified: plant and animal organisms (12…39 %), leaching of Fe- and Cu-containing minerals (10…29 %). The article shows that in the formation of the chemical composition of the water of the rivers of the studied region is determined by the factor of ion from the rocks on which the formation of the catchment. A factor characterizing the local conditions of river runoff formation has been identified - the process of groundwater discharge, which is manifested in changes in the concentrations of silicon and nitrates. In addition, a negative dependence of changes in the content of silicon ions and nitrates on temperature. The originality of the study is based on an integrated approach, which includes research based on available data in the State Agency of Water Resources of Ukraine, which takes into account the principles of biodiversity conservation, sustainable use of water resources, river management and basins, monitoring and evaluation of their status. In the future, the proposed approach may be the subject of research in the direction of establishing factors that characterize the local conditions of formation of river runoff, including taking into account the man-made load on it.

Geophysical techniques Ground Penetrating Radar (GPR) and Electrical Resistivity Tomography (ERT) are used for the geological mapping and description of inner structure of sediments of the Upper Dnieper zone. Geophysical data assisted locating the boreholes and correlation the horizons between them. The information obtained by geophysics provided a basis to identify the rerouting of the upper Dnieper valley due to the Valdaian glaciation. GPR data on frequencies 50–250 MHz allowed to describe the upper part of geological section, ERT provided data up to 80–100 m depth. We performed the modified focusing inversion, based on major boundaries obtained with GPR, to correct ERT inversion model.

The article is devoted to the study of sediment runoff, especially one of the characteristics that reflects erosion processes in the catchment area, water turbidity using the example of the rivers of the Sumy region. The main purpose of the article is the spatial and temporal analysis of the turbidity indicators of the rivers of the Sumy region (left-bank tributaries of the Dnieper). The article highlights information on the sediment runoff of the rivers in the region for the entire period of observations, describes modern own studies of the turbidity of river water and establishes the features of the formation of sediment runoff in the rivers of the region. It was found that the indicators of turbidity of river water grow in the direction from north to south of the study area, in the zone of mixed forests are minimal, and in the forest-steppe – maximum; high values of the average turbidity index characteristic of small rivers in the region, аmong the average rivers, the maximum values were recorded for the Sula and Vorskla rivers; during floods, turbidity values are maximum, and during low water periods, they are minimal; there is a tendency to an increase in the indicators of maximum and average turbidity of river water. Particular attention is paid to the influence of river regulation on turbidity indicators. It was found that the deceleration of water exchange is facilitated by the accumulation of sediments in the channel above the dam (high indicators of the thickness of the silt layer), and also below the dam (the creation of a channel island, probably due to the uneven throughput of the dam’s gate valves, which creates a different flow rate from the right and left banks). Decreased flow velocity, increased water turbidity and, as a consequence, siltation, deterioration of river water quality (appearance of swamp odor, decrease in transparency, color change) leads to changes in the species composition of aquatic organisms, extinction of river species and the appearance of atypical river species, overgrowth. In their conclusions, the authors argue that sediment runoff is formed mainly due to washout from the surface of the catchment area, high turbidity indicators in rivers whose basin is more prone to erosion, where the indicators of plowing of the basin surface are maximum, water protection zones and coastal protective belts are destroyed, but when studying the turbidity of river water it is necessary take into account additional factors.

Objective. Analysis of the results of systematic observations of the indicators that characterize the "blooming" of the water of the Dnieper River in space-time aspect, and providing recommendations for its prevention. Materials and methods. To assess the water quality of the Dnieper River, an array of data from the State Agency of Water Resources "Dnieper Basin Water Resources Management" (2015–2017, 906 samples), the State Water Cadastre (2016), "UNHC Ministry of Health" on the state of water in Ukraine (1992–1994), “National Report on Drinking Water Quality and the State of Drinking Water Supply in Ukraine” (2005–2016), Lithuanian Waste Management Regulation (2006), Council Directive 91/271/ЄEC. Methods were used for data processing: analytical, statistical, correlation, mathematical modeling. Results and conclusions. A high content of phosphates and organic substances in the water of the Dnipro river in the spatial-and-temporal section is demonstrated, which indicates a natural and anthropogenic contamination and will lead to the potential problems with the contamination of tap drinking water made of the Dnipro water. It is proved that one of the priority tasks today should be to reduce the content of organic matter, phosphorus and nitrogen in surface waters, which can be achieved by establishing coastal strips and provided by law, as well as the use of modern technologies for industrial and domestic wastewater treatment, this requires regulation. Further harmonization of Ukraine’s water legislation with European legislation will help prevent water-related morbidity.

Full textAbstract:
The current state of ecosystems of rivers of Ukraine - their natural features and consequences of powerful anthropogenic activity are analyzed. The problem of coastal areas of rivers and reservoirs is considered. Methods of rehabilitation of the cascade of Dnieper reservoirs and their coastal territories are determined.
Extensive farming with the destruction of coastal lands up to 80-90% is one of the main factors in the ecological crisis of river ecosystems. The floodplains of most small rivers of Polissya are developed for agricultural lands by almost 50-60%, Forest-steppe and Steppe - by 70-90%. Nevertheless, the efficiency of agricultural land use in Ukraine is lower than in Europe and developed countries. Agricultural fields are located on the slopes and floodplains of rivers, so the erosion of coastal areas has reached unprecedented proportions.
The creation of the Dnieper reservoirs has created a number of environmental problems, led to a sharp change in the basis of local erosion. One third of their total length is actively destroyed by wind waves and denudation processes, runoff and other types of currents. The area of land lost as a result of the destruction of the shores is already about 6.5 thousand hectares. The destruction of the cascade shores annually leads to the loss of a significant amount of coastal land, affects the use of the shores and adjacent areas, causes emergencies, accidents and catastrophes, especially in settlements where the negative impact of natural factors is exacerbated by man-made factors.
The condition of the coastal area directly affects the condition of the water area. Urban planning of coastal areas should help preserve and maintain the natural balance of the river ecological system - the establishment of restrictive "green lines" and water protection zones, shore protection, creation of recreation areas and their improvement, paving tourist routes, restricting protected areas and more. These urban planning measures should take into account the zonal features of rivers and take into account the uniqueness of each river ecosystem in Ukraine.

Full textAbstract:
One of the main features of the quality of the Dnieper water is the content of natural organic substances which determine the water oxidizability and color indexes. A special problem is that organic substances are poorly removed by water treatment plants. A significant problem in the operation of water treatment plants is the unpredictability of annual changes in the quality of Dnieper water, which complicates logistics management, for example, the supply of reagents. Many years of experience related to the Dnieper water supply station in Kyiv (DnWS) have led to the hypothesis that these changes are in some way related to the cycles of solar activity.
The purpose of this work is to test this hypothesis to substantiate the possibility of predicting the quality of Dnieper water depending on the action of such a global factor as solar activity. The work was performed by statistical methods using 60-year results of Dnieper water analyzes provided by the DnWS laboratory, as well as Wolf numbers (Sunspot Numbers) provided for free use by the Royal Observatory of Belgium. The influence of solar activity on the quality indicators of Dnieper water, especially in its peak and post-peak periods, has been statistically confirmed. The interaction of biological and physicochemical parameters as factors influencing water quality is shown.
Conclusions. As a result of the construction of six reservoirs in 1931-1976, the Dnieper from the river actually turned into a network of water bodies. Now these reservoirs are a kind of reactors in which water is treated by electromagnetic solar radiation, which leads to the cyclic transformation of phytoplankton and natural organic matter. Taking into account the cycles of solar activity, the logistical planning of the operation of water treatment facilities receives an independent "base", changes in which can be predicted with some reliability for years to come.

AbstractThe article focuses on the problem of structure degradation and ecosystem functioning – the urgency that identifies the relevance of operations at a strategic level aimed at providing the integrated assessment of ecological stability of water. Determination of water quality indicators were divided into blocks according to the criteria of salt composition, according to chemical saprobological indicators and the content of specific substances of toxic and radiation action. According to the results of block analysis, the integrated ecological index of water quality was determined by the dependence of water quality on the indicators of ecological stabilization of the landscape and the structure of biotechnical elements. The article determines the relationships between worsening quality of surface waters and stabilization or destabilization of the landscape structure. The research was conducted on medium and large streamflows on the Right Bank of Polesie region of the Dnieper-River cascade within which the tracts of land were identified and the landscape ecological stability (CESL1) and landscape biotechnical elements coefficients (CESL2) were determined. The retrospective analysis was performed of the surface water features on the Right Bank of Polesie region of the Dnieper-River cascade and the main trends in salt block indicators, trophic and saprobiological block indicators, and in the content of toxic and radioactive substances at observation sites were estimated. Based on obtained data, the integrated assessment in trends of surface water quality on the Right Bank of Polesie region of the Dnieper-River cascade was made and the main parameters and scale of stabilization and destabilization of landscape impact on the water quality formation were defined.

According to Dr. Yu. Boltrik’s works the Scythian royal barrows were situated on the high places (watersheds) as well as along the roads. One of the biggest roads marked by Oguz, Solokha, Kozel, Chertomlyk and Alexandropol barrows run in meridional direction and crossed the Dnieper. The Dnieper crossing was a start point in barrow creation: the later is a barrow, the more distant from the Dnieper crossing it is placed. Kozel and Chertomlyk barrows situated across the Dnieper (Kozel on the left coast, Chertomlyk — on the right one), both dated to the second half of the 4th century BC, are similar in planigraphy, quantity of buried horses and some details of their arrangement.
In both barrows the horses were buried in special tombs situated to the West of the central tomb. Each horse tomb consisted of three large rectangular separate pits formed a line situated North-South.
In both cases 11 horses were buried. Their bridles were made of two metals: of silver and gold in Chertomlyk and of bronze and silver — in Kozel. Some had also saddles with golden plates and some had bronze breast (neck) dressings.
We compared the arrangement of horses in the tombs of Kozel and Chertomlyk concerning the Dnieper crossing and observed a kind of bilateral symmetry in it. So we may suppose they had in mind this crossing not only constructing barrows but burying horses too.
River crossing in archaic cultures is a border dangerous to overcome. Because of that some rituals should be performed and some constructions installed at that place. Near the Dnieper crossing a group of Scythian barrows is known. The Dnieper direction in this place is latitudinal and the direction of road — meridional, so the place of crossing looks like a center of sacred space, and the way to it is also sacred.
So we do not except the Dnieper crossing was significant for arranging horses’ tombs in Kozel and Chertomlyk barrows.

Topicality. The river potential of Ukraine has great prospects in the direction of connecting with Europe at the expense of increasing the transit capacity of the Danube and the Dnieper rivers taking into account the access to the Black Sea. River transport has a number of advantages over land, in particular: ready natural ways; use of water flow; the ability to transport any cargo and passengers simultaneously; safety and environmental friendliness; high bandwidth; high degree of reliability and timeliness of delivery; low cost of transportation, which leads to fuel economy, etc. It should be noted that to date, taking into account the uplift tariffs for transportation by rail and inconvenience of use of motor transport, organization of container service on the Dnieper is the most promising and in demand.Aim and tasks. The aim of the article is to determine the organizational and economic bases of river container transportation in Ukraine. In accordance with the stated aim, it is necessary to analyze the cargo base of river container transportation in Ukraine; to formulate priorities of development of river navigation of Ukraine; to substantiate the efficiency of using container technology of cargo transportation by inland waterways of Ukraine.Research results. The complex of measures for the development of container cargo transportation by inland waterways of Ukraine was proposed, the analysis of the market of river container transportations in Ukraine in comparison with the countries of the European Union and the USA was carried out, the main problems of development of inland water transport were identified and measures for their further development and operation of inland waterways of Ukraine taking into account the prospect of their integration into the European transport network.Conclusion. Ukraine has significant potential for organizing logistics schemes for cargo transportation involving river transport in several directions. The presence, albeit somewhat obsolete, a powerful infrastructure base, a convenient geographical location and the availability of traffic flows that can potentially be transported by inland waterways, creates the preconditions for the restoration and development of this transport area.

Full textAbstract:
Studies of the variability of the minimum flow of water, which relates to the extreme regime characteristics of river water flow during periods of low water, are relevant. Such information, in general, is the limiting criteria for water consumption, water use and protection of water resources from pollution and depletion, and sometimes are indicators of danger and catastrophe, in particular, during periods of prolonged droughts. This is especially important in the conditions of modern climate change, in which the probability of occurrence of extreme hydrological phenomena increases significantly. To assess the long-term variability of the absolute annual minima of the flow of water from the rivers of Ukraine, sequences of minimum daily average water flows for a multi-year period from 294 gauging stations from the beginning of the observations to 2015 inclusive were formed. The methods of statistical processing of random variables (for determining the norms of runoff, coefficients of variation and asymmetry) and random functions (for constructing integral difference curves) were used. The study of the spatial specifics of changes in the absolute minima of the water flow of the rivers of Ukraine is based on the "Hydrographic zoning of Ukraine's territory". According to it, the territory of Ukraine is divided into hydrographic units — nine areas of river basins and nine sub-basins. The absolute annual minima of river runoff on the territory of Ukraine are recorded during periods of summer-autumn or winter low-water periods. High values of absolute annual minima in the modules of water flow are observed on the rivers of the Carpathian region and reach 8,7 l· s – 1 · km – 2. Basically, such values are on mountain rivers with small catchment areas; on rivers with large catchment areas that extend from the mountain and foothill areas of their flow to the plains, up to 0,9 l· s – 1 · km – 2; on the rivers of the Crimea, the absolute annual minimums in the water flow modules, in the vast majority, vary from 0,0 to 1,8 l· s – 1 · km – 2. Regarding flat river basins, for the rivers of the Vistula basin, the sub-basins of the Pripyat and the Desna, the left-bank part of the Dniester river basin, the range of changes in the absolute annual minima of the water flow modules is 0,20 ÷ 2,9 l·s– 1 ·km– 2. To the south of the indicated flat river basins, the ranges of absolute annual minima are gradually decreasing. On the rivers of the sub-basin of the Middle Dnieper there is 0, 19 ÷ 1,19 l·s– 1 ·km– 2, the subbasin of the Lower Dnieper – 0,04 ÷ 0,42 l · s – 1 · km – 2, the basin of the Southern Bug – 0,09 ÷ 1,75 l· s – 1 · km – 2. And in the basin of the rivers of the Black Sea region there is 0,0 ÷ 0,001 l· s – 1 · km – 2. For river basins of the flat part of Ukraine, the variation of annual minima is within 0,30 ÷ 2,83, the smaller one is the range of variability for the rivers of the Carpathian region – 0,20 ÷ 0,90. The asymmetry coefficients of the minimum river flow during the year for the whole territory of Ukraine range from negative -0,11 ÷ -2,01 to positive values 1,30 ÷ 6,4. The long-term variability of the absolute annual minima of the water flow of the rivers of Ukraine has been studied. Analysis of generalized difference integral curves for the entire set of rivers within the basins and sub-basins of the hydrographic zoning of Ukraine showed for the period of joint observations from 1947 to 2015 marked cyclic component. It manifests itself in a long period of decreasing absolute annual minimum values until 1968-1974, then there is an increase, and at the present time period, after 2006-2010, there is a tendency to decrease.
