Abstract:

Оleshkivski Sands (Oleshia) are one of the morphosculptures on the Left bank of the lower part of Dnipro river, which is formed on alluvial and periglacial deposits. The article clearly identifies the location of these sands among other morphosculptures of the Left bank of the lower part of Dnipro. In view of the ambiguity, two regions of the Left Bank are considered separately – nearby arenian sandy-loamy geocomplexes with the presence of extremely specific sandy hilly-depressions geocomplexes and the territory of the hilly-lowland plain (Kardashynka lowland), which is located between the Dni

Abstract:

Modern aeolian relief is widespread in the forest-steppe landscapes of Transbaikalia. Valleys of the Selenga River and its inflows are the areas covered by ancient sandy deposits. Human impact in dry climatic conditions causes intensive wind erosion and formation of open and moving sands covered with sparse plants. The flora and vegetation of such landscapes notably differ from surrounding territories. It’s particularity is caused by presence and domination of plant species usually seen on open sands. Despite of numerous publications describing the sandy dunes of Transbaikalia, the psammophyte

The appropriate choice of shear strength of liquefied sands is an important component in seismic slope stability evaluation. Several factors affect the undrained steady-state strength (Sus) of sands.

Fines content was found to be the major factor affecting Sus. This was verified experimentally for one sand.

This is the first study to focus on the abundance of naked amoebae inhabiting a sandy beach.

While most of the inner shelf is covered with fine silts and clays, sandy sediments occupy a linear belt in the outer parts (-25 to -30 m) of the shelf. These moderately sorted sands are considered to be relict and deposited during a standstill of the Holocene transgression.

To this end, the fine-grained (<63 μm) aeolian-fluvial sediments and loess deposits, which were taken from the Onqin Daga Sandy Land, the Horqin Sandy Land, the Hulun Buir Sandy Land and the Songnen Sandy Land, and from the downwind loess section (L1), respectively, were analyzed to construct the heavy mineral data set of NESL source and sink and to evaluate feasibility of the heavy mineral meth

AbstractComprehensive environmental studies taking under consideration the structure of the radiation balance during the vegetation growing seasons of 2001 and 2002 were carried out on the open sandy surface of the area called the Błędów ‘desert’ located on Silesian Upland. The research in each site covered the composition of plant species, their age and height, the condition of the substratum, the composition and structure of the soil and the meteorological conditions with elements of the radiation balance. The article presents some part of the research on meteorological elements and their im

The granulometric, morphoscopic and mineralogical analyzes of the surface sediments from the bottom of the lake collected in March 2021 and the use of the Hjulström model, made it possible to determine the sedimentological characteristics and predict the sedimentary processes in the lake. The sedimentological study makes it possible to identify four lithological facies: sands, muds, gravels and mixed sediments. Sands and gravels are the most abundant, with a predominance of

Abstract:

The object of the research is the unique collection of samples of eluvial and aeolian sands collected in the tropical (Vietnam) zone and the zone with the temperate humid sharply continental climate (the Tunkinsk’s depression in the Baikal region). Traces of structural connectivity were established by visual inspection of the samples in laboratory conditions using a four-fold magnifier. "Cohesive" clayey (ps*) and ordinary sandy (ps) varieties were identified. The mineral composition of the collection sands was determined by the method of quantitative immersion analysis of the 0.25–0.05 mm fra

Abstract:

In the natural state, thixotropic phenomena in soils most often occur under external loads of a dynamic nature: earthquakes, vibrations from moving vehicles, working machines and mechanisms. Data on the study of soil thixotropy indicate that under dynamic load to reduce the strength and go into a liquid state can be dispersed soils of different types, genesis and age. The influence of dynamic loading is especially significant in the case of poorly compacted and water-saturated sandy and clay soils. At dynamic loading there can be both consolidation of soil and accordingly increase in its

The Oligocene Eigenbilzen Formation and Miocene Bolderberg Formation were studied along the Albert Canal in the southern Genk municipality, eastern Belgium. Previous studies have subdivided the Eigenbilzen Formation into geophysical subunits based on borehole logs. Correlations of borehole logs with a deep Cone Penetration Test reveal that this subdivision is also geotechnically distinct. The Eigenbilzen Formation is unconformably overlain by the Houthalen Member (lower Bolderberg Formation), which holds a late Burdigalian age according to the dinoflagellate cyst analyses on borehole samples b

Investigating and evaluating the quantity and spatial distribution of arable sandy land in arid and semiarid sandy areas is of great significance for the sustainable development and utilization of sandy land resources and the maintenance of the stability of the structure and function of regional ecosystems. Based on the characteristics of sandy soil, being without structure and susceptible to wind erosion, this study used the limiting factor exclusion method to investigate and evaluate arable sandy land in arid and semiarid areas.

Abstract:

The productivity of sandy soils is mostly limited by their low water-holding capacity and excessive deep percolation losses, which reduce the efficiency of water and fertiliser use by plants. The effect of a crosslinked-type polyacrylamide, ALCOSORB 400, on water-holding capacity of a sandy soil, siliceous sands, was studied under the laboratory and glasshouse conditions. Water-holding capacity of the soil exposed to 0.01 MPa increased by 23 and 95% by adding 0.03 and 0.07% of polyacrylamide to the soil, respectively. This indicated that the soil treated with polyacrylamide was able to store m

The unsaturated soils mechanics is strongly related to the suction phenomenon that occurs between solid soil particles, which changes when the soil water content does not remain constant. The soil-water characteristic curve (SWCC) provides information related to suction and water content of the soil; and to obtain such a curve different direct and indirect methods can be used. In this research the soil-water characteristic curve for sands is obtained through the implementation of the filter paper test.

A brief description of the morphology of the aeolian relief, characterized by the predominance of deflationary forms over accumulative ones, is given. Among the forms of active deflation, deflation basins dominate here, separated by elongated deflation inselbergs, composed of sands of lacustrine, alluvial, deluvial-proluvial, and aeolian genesis.

This article assesses the pullout performance of ribbed metallic strips embedded in fill soils that do not conform to conventional design criteria for mechanically stabilized earth (MSE) walls. These alternative fill soils include gravelly and sandy recycled aggregates from construction and demolition waste, artificial and natural sands, and fine-grained lateritic soil. The research included soil characterization tests and large-scale pullout tests, conducted as part of this study. The results showed that the reinforcement pullout behavior was similar for recycled, artificial, and natural sand
