Abstract:

Reservoir rule curves are essential rules for store activity. This investigation connected the Genetic Algorithm, Firefly Algorithm, Bat Algorithm, Flower Pollination Algorithm, and Tabu Search Algorithm associated with the store reproduction model to look through the ideal supply standard bends, utilizing the Huay Ling Jone and Huay Sabag supplies situated in Yasothorn Province, Thailand, as the contextual investigation. Memorable inflow information of the two repositories were utilized in this investigation, and 1,000 examples of engineered inflows of stores were utilized to recreate the repository activity framework for assessing the acquired principle bends as displayed as far as water circumstances. Circumstances of water lack and abundance water appeared as far as the recurrence extent and length. The outcomes demonstrated that GA, FA, BA, FPA, and TS associated with the reservoir simulation model could give the ideal principle bends which better moderate the drought and flood circumstances contrasted and current guideline bends.

Abstract:

The shore zone of reservoir is an important transition zone between water ecological system and land ecological system in exchange material, energy and information. As a buffer area on the edge of the reservoir, the reservoir shore zone plays an important role in water and soil conservation, and purifies water quality. Most of the previous studies on reservoir shore focused on large reservoirs, while the number of small and medium reservoirs are often important source of local production and living water, therefore, it is necessary to study the vegetation pattern and its ecological effect of small and medium-sized reservoir shore zone, and put forward the suitable plant species in different conditions and optimize pattern of small and medium-sized reservoirs, thus improve the ecological effect of water and soil conservation, and purifying water quality. That would prevent and reduce the silting of small and medium-sized reservoir, and enhance the water storage capacity.

Abstract:

Abstract This paper provides an analysis of water quality in three newly constructed small water retention reservoirs (Rudziczka, Niemysłowice I and Paciorkowy) located in forested areas of the forest district Prudnik in the Opolskie Province (southern Poland). The main purpose of these reservoirs is not only water retention, but also flood safety, fire protection, recreation and ecology. This paper presents the results of research carried out in December 2014 and May 2015. The assessment of water quality was performed in accordance with the applicable provisions on water quality assessment. Moreover, an assessment of eutrophication of water and of the usability of water in reservoirs is given (an analysis of suitability of water as a fish habitat). The research shows that the investigated waters are of quality class I in terms of the values of electrolytic conductivity, nitrates, nitrites, dissolved oxygen CODMn, calcium, magnesium and general hardness. In terms of the temperature (the Rudziczka reservoir), and the content of ammonia and phosphates they were of quality class II. The reaction, BOD5 and sulphates and chlorides content exceeded the threshold values for class II. It was also found that the investigated waters are not eutrophic. Based on the indicators such as reaction, dissolved oxygen, ammonia nitrogen and temperature, the waters in all the reservoirs except for Rudziczka met the quality requirements for habitats of salmonids and cyprinids. The living conditions for fish are deteriorated most by the increased levels of BOD5 and of nitrites in the Rudziczka and Paciorkowy reservoirs. The analysis of seasonal fluctuation in concentrations of water quality indicators in the investigated water bodies showed that in winter the concentrations of indicators were higher for nitrates, phosphates, electrolytic conductivity, calcium and general hardness and lower for temperature, reaction, nitrites, ammonia and dissolved oxygen. While the water in the Paciorkowy reservoir had the worst quality, the surface water in the Rudziczka reservoir had the best quality. The research initiated in small forests water retention reservoirs provides preliminary information on water quality and the importance of investigated reservoirs for increased retention.

Abstract:

The limited water level of reservoir by stage, fully consider the seasonal variations of the average annual precipitation characteristics in every reservoirs control catchment. Its not only ensuring the rational use of water resources, increasing economic and social benefits to the reservoir, but also ensuring the safety of flood control reservoir flood season, to protect people's lives and property. Determine flood limit level for small reservoir by installments should consider the balance between the economic benefits from improving the water level and the consumption of human and financial resources caused by the installments flood water level adjustment. At the same time, the water resources should be intelligent used in order to let the level of reservoir get in normal. This paper, according to the characteristics of small reservoir, calculated on the reservoir storage capacity can be increased basis of the existing flood control capacity through calculating the value of membership function during reservoir flood season. So that the new limited water level can be obtained after calculating the reservoir capacity increase according to the capacity-water level graph.

Abstract:

The intensification of agricultural production brings problems related to water erosion, even to the upper parts of river basins. Soil particles that have eroded from unprotected agricultural land are often deposited in small water reservoirs, the efficiency or function of which might be compromised. This study presents an analysis of changes in the retention capacity of a small water reservoir over a period of 8 years. Within the study, a detailed bathymetry of the reservoir was conducted using an acoustic Doppler current profiler. The results, when compared to a 2008 geodetic survey, showed that the retention volume of the reservoir was reduced by only 2%, which was also confirmed by mathematical modeling. The possibility of strengthening the reservoir’s role in flood protection was also investigated. A flood wave with a return period of 100 years was estimated using a design storm approach. A simple numerical model was proposed to transform the flood wave through the reservoir by considering four different scenarios of the elevation of the initial water level. The model, which is based on a water balance equation, uses simple hydraulic relationships to control the discharge through the reservoir’s outflow objects. The results demonstrate that by reducing the initial water level, significant improvements in terms of the flood peak’s attenuation and a longer time to peak values could be achieved.

Abstract:

The aim of the study was to evaluate catchment area impact on small water reservoirs condition in Podlasie. The researches were conducted in two different catchment areas. Topiło reservoir, located in Podlasie area in the south-east of Białowieża Forest, has typical sylvan catchment. Second reservoir, Dojlidy, is located also in Podlasie, in the south-east of Białystok as a part of Dojlidy Ponds. In contrast to Topiło, Dojlidy has agricultural catchment. Water samples collected from five sites along each reservoir were analysed for the presence of total nitrogen and phosphorus, chlorophyll “a”, reaction, turbidity and conductivity. Researches took place in spring, summer and autumn 2013 (Topiło Lake) and 2014/2015 (Dojlidy). The lowest trophic state was observed in autumn and the highest in summer. Because of the high loads of phosphorus received by the reservoirs, this element did not limit primary production. Calculated TSI values based on total phosphorus were always markedly higher than calculated on chlorophyll-a and total nitrogen. Both reservoirs demonstrated TSI indexes specific to hypertrophic lakes due to large amount of total phosphorus.

Abstract:

Abstract. Small reservoirs are widely used for storing water, especially for irrigation purposes. During the last decades, in Italy many of these reservoirs have been dismissed, becoming an untapped resource. As a matter of fact, maintenance problems connected to these structures together with their natural tendency to silt have favored the use of other water supply resources such as withdrawal from wells. The increase of drought periods and the high water volume demand for agricultural purposes suggest to evaluate a full and rational use of all water resources, leading to a rediscovery and enhancement of untapped resources. Specifically, this research focuses on small reservoirs and on their potential contribution to a sustainable water management in agriculture. Unfortunately, there are no reliable data on their number, spatial distribution and potential storage volume. The aim of this work is to define reservoir spatial distribution and evaluate potential available water volumes. The upper Tiber river basin has been selected as a case study for the methodology proposed. The work starts from the acquisition and re-elaboration of the old census of small reservoirs, evaluating, through GIS and regression techniques, the distribution over the territory and the available volumes. Then the reservoir census and the derived database were updated for the period from 2015 up to 2019 introducing combined computational procedures of remote sensing techniques and GIS, based on satellite images and water index calculation. The results of the semi automatic procedure used show good performance in lake identification, making it a promising tool for a fast and reliable water body identification and evaluation in wide areas.

Abstract:

The paper deals with the analysis of a river’s regime of a small watercourse and the evaluation of its changes after the construction of a small water reservoir. The aim of the work was to analyse 12 years of flow rate measurements at two profiles of a small watercourse, between which a small water reservoir was built, in the middle of the period of the measurements. The analysis uses traditional characteristics (average flow rate, discharge volume), as well as modern indices from applied hydrology (Richards-Baker flashiness index, hydrogram pulse analysis), which study the variability of the flow rate in hourly and daily intervals. The evaluation showed that at the average flow rate, the effect of the water reservoir was the smoothening of the peak flow rates and prolonging the duration of the discharge waves. At higher flow rates, the water reservoir causes a delay in the culmination and in terms of discharge balance causes a decreased discharge volume, in particular during the vegetation period.

Abstract:

Small water bodies, until recently considered as wasteland, are an essential element of the so-called small water retention. Their main use can vary significantly, but they always play a positive role by increasing water resources and enhancing the natural values of the landscape. Moreover, by increasing bio- diversity thanks to plants forming habitats for many species of flora and fauna, small water bodies act as a biofilter, improving water quality. But these small reservoirs belong to the groups of waters that are most exposed to damage, especially within the catchment area. Because of the invaluable role of small farmland water bodies, a study was undertaken to investigate their phytocenotic structure. In addition, an attempt was made to assess the level of threats and to indicate their role in the development of habitat conditions. The investigated reservoir was created in 2007. Before that time, it functioned as a part of the Zemborzycki reservoir, as they were close to each other. Almost the entire surrounding of this small reservoir consisted of farmland. In 2011 a revitalization project was carried out in the reservoir. Plants typical for wetland habitats were mainly introduced, while synanthropic vegetation was removed. Based on chemical and physical analyses, it can be concluded that the investigated reservoir serves as a natural biofilter thanks to the qualitative and quantitative changes in the structure of macrophytes. After the revitalization project, the investigated pond gained new aesthetic and ecological qualities.

Abstract:

On the base of the obtained materials and considering the factors of composition features, dynamic mechanism and deformation-motion characteristics, the three-dimension numerical simulation model is generated. And the parameters of Young module, passion ratio and shear strength are obtained. Then the calculation conditions are extracted from the combination of the inducible factors and the displacement features. After that, the deformation failure are simulated by the FLAC3D code, and the results are compared to the monitoring data. The results indicate that the influence of the water impoundment on the stability of the landslide is small, the water descending is large. For the front part monitoring points, the amounts and the curve shapes of the numerical calculation results are accord with the practical ones, but for the monitoring point in back there are only the similarities in the curve shapes, and the amounts are a little smaller.

Small reservoirs catch and store water for long periods and they decrease streamflow and increase ground-water recharge. A field monitoring program provided the measured water depth for four years in several reservoirs in the Republican River Basin where there are concerns about their aggregate effects in the basin. The daily water budget operation for one reservoir was developed. Daily seepage rates were estimated by using precipitation, inflow and evaporation which was assumed equal to grass reference evapotranspiration (ET0), that average 120 to 150 cm/yr, along with the measured stage-storage and stage-surface area relationships. Two computer simulation modules, written in FORTRAN 95, were developed to estimate 1) overflow and gross seepage and 2) potential for ground-water recharge underneath the reservoir. Required daily input data are precipitation, ET0, and inflow from the watershed area. Required reservoir site characteristics include stage-storage and stage-surface area relationships, a standard seepage rate (S0) at 14 different levels in the reservoir, soil-water and plant-growth characteristics and a monthly crop-residue factor. The gross seepage module calculates water depth that determines daily overflow, the water-surface area for evaporation and the head of water on the 14 levels to cause seepage losses. If a level is not inundated, seepage is zero. If a level is inundated less than 0.3-m, S0 is used. When the water head (hL) on a level exceeds 0.3 m, the seepage rate (SL) is increased by, SL = S0 * (hL/0.3)0.25. This relationship was chosen after testing several exponent values between 0 and 1. The modules were calibrated on one reservoir and verified on two others in northwestern Kansas. Results showed runoff from the watersheds averaged about 1.2 to 1.6 cm/yr from the average annual precipitation of 46 to 62 cm. The three reservoirs reduced streamflow at the reservoir site by 74 to 97%, but 90 to 95% of the retained runoff was calculated to contribute to ground-water recharge. Several sensitivity analyses for model inputs were done. Results showed that, the ratio of the average annual inflow volume from the watershed area to the reservoir storage volume was the most sensitive input variable tested.

Abstract:

Small reservoirs have become increasingly widespread across semi-arid regions, due to their ability to reduce transport of eroded soil and harvest scarce and unreliable rainfall for local users. The scale and geographical dispersion of these multiple hydro-social systems restrict their investigation, leading to difficulties in assessing their agricultural potential, their cumulative influence on runoff, and in identifying strategies to support riparian farmers. This research sought to develop a multi-scalar interdisciplinary approach to assess water availability across multiple small reservoirs and understand hydrological and wider drivers’ influence on associated agricultural practices. An Ensemble Kalman Filter approach was developed to combine 30 m Landsat flooded surface area observations with a daily hydrological (GR4J + water balance) model on 7 gauged reservoirs. Data assimilation, providing near-real time corrections, reduced runoff uncertainties generated by highly variable and localised rainfall intensities and lowered daily volume root mean square errors (RMSE) by 50% compared to the initial rainfall-runoff model forecast. Compensating for Landsat’s reduced temporal resolution and correcting outliers, the method correctly reproduced flood dynamics of 5 ha lakes (R²=0.9). Validated against extensive field data over 1999-2014, the method notably establishes Landsat imagery’s ability to assess annual water availability on ungauged reservoirs as small as 1 ha (RMSE circa 25%). Applied to 48 small reservoirs and 546 Landsat 5-8 images, the treatment chain identified the significant water scarcity and unreliability that impedes agricultural development on 80% of lakes in the Merguellil upper catchment (Central Tunisia). In parallel, rapid surveys, quantitative questionnaires and semi-directed interviews confirmed minimal withdrawals, yet highlighted the diversification of practices and the peripheral benefits accompanying small reservoir development. Many farmers lack the capabilities to increase their withdrawals and suffer physical and economic water access difficulties, mismanagement, compounded through limited and short-term government assistance. Individual successes resulted from farmers’ economic resilience and means to secure alternate water supplies during dry spells. Faced with limited storage capacities and prolonged droughts, small reservoirs must in this climatic context retain their supplementary irrigation focus and not strive to support widespread intensification of irrigated practices.

Abstract:

State of rural water resources and selected new challenges of water resources management in rural areas in Poland are presented Problems of influence small water reservoir for water quality is presented. It is commonly believed that every kind of reservoirs should collect and reduce the nutrient contamination (N, P, heavy metals). The presented results show that water reservoirs (both pre- and main reservoirs) are a source of water pollution. The reservoirs fed by waters of inadequate or poor quality are an additional source of contamination, which accelerates the process of eutrophication. However, as the literature shows, well-designed pre-reserviors of optimum size can remarkably reduce the phosphorus import into reservoirs and help to control eutrophication from non-point sources

Abstract:

Abstract Poor formation permeability and near well bore damage may limit water injectivity into the reservoir in a water injection project. This paper seeks to evaluate the effect of radial drilling technique on water injectivity and oil recovery in water flooding operation. Radial drilling technology utilizes hydraulic energy to create lateral perpendicular small holes through the casing into the reservoir. The holes may extend to 100 m (330 ft) into the reservoir to access fresh formations beyond the near wellbore, and damage zone. A black oil simulator (Eclipse 100) was used to modeling a lateral radial drill from the borehole into the reservoir, and that of a conventional perforation of the wellbore respectively. A simulation study was carried out using various presumed radial drill configurations in determining injectivity index, displacement efficiencies, recovery factor and water cut of the process. The determined results were further compared with that of the conventional perforation process case respectively. The results show a significant improvement in water injectivity in radial drill case with the increasing length and number of radials as compared to the conventional wellbore perforation case. The determined Recovery factor shows a progressive increase with increase in the numbers of radials drilled, irrespective of the radial length. However, it was observed that, the more the number and length of the radials drilled in to the reservoir, the higher the water cut from producer wells. Radial Drilling Technology, therefore, has a promising potential to improving water injectivity into the reservoir and thereby optimizing oil recovery in a water flooding operation.

Abstract:

Low recovery factor is identified as the main problem encountered in the heavy oil production from a strong bottom-water-drive reservoir. Unlike for conventional oils, where the expected recovery from such reservoirs could be very high — in excess of 50 percent, the expected recovery factor in heavy oil water-driven reservoirs is less than 20 percent. In this study, a qualitative analysis of the well productivity mechanisms specific for heavy oil reservoirs with bottom water is provided. The objective is to understand what make the production of heavy oil different to that of lighter oils, identify the mechanism that mostly hamper the well’s productivity and recovery efficiency. Many believe the by-passed oil due to water coning is the major cause of low ultimate oil recovery in heavy oils underlain by strong bottom water. However, in this paper, we identify another important parameter affecting recovery efficiency in such reservoirs, which hasn’t been recognized by others and its effect on recovery process is significant. The mathematic modeling and numerical study lead to a new finding: due to the aquifer’s influence on pressure response in reservoir, a no-flow boundary at xi is established, where xi is often much smaller than that of the actual reservoir size xe. The oil out to the distance xi is immobile and become bypassed oil, which accounts for large amount of the OOIP. Even the water coning can be effective controlled; the ultimate oil recovery factor will not be improved significantly if the small mobilized oil zone can’t be enlarged. An analytical solution is derived in this paper to calculate the actual drainage radius. The validity of this analytical solution is confirmed by numerical simulation runs.
