Opis:
The Sianjo-anjo reservoir is used to meet the need for downstream clean water. Land activity at the Sianjo-anjo reservoir watershed can potentially increase the rate of erosion and the silting of rivers and reservoirs due to sedimentation. Reservoir siltation is a crucial challenge for reservoir management because it can reduce its function and affect its service life. However, sediment yield is often overlooked in reservoir planning and environmental assessment. This study aims to predict the rate of land erosion and sediment yield, and create an erosion hazard map of the Sianjo-anjo reservoir watershed. The study used a Geographic Information System, GIS-based Universal Soil Loss Equation (USLE) method and discovered that the erosion rate of the Sianjo-anjo reservoir watershed was between 35.23 Mg∙ha-1∙y-1 until 455.08 Mg∙ha-1∙y-1, with 95.85% classified as the low level, 0.03% as moderate, and 4.12% as high. Meanwhile, the sediment yield from the Sianjo-anjo reservoir watershed was 218,812.802 Mg∙y-1. USLE is vital to identify areas susceptible to erosion and crucial for reservoir sustainability. Furthermore, it is necessary to plan good sediment management. Long-term land conservation is required to maintain storage capacity and ensure effective operation of the reservoir.

Opis:
The total content and relationships between macroelements (Ca, Mg, K, Na, Mn, Fe and Al) and soil properties along the soil catena in the hilly valley of Lier River, S Norway, are discussed in the paper. The upper and middle part of the Lier River valley is covered with Stagnic Phaeozems formed from silt loam and sandy loam. In some parts of middle slope, Haplic Phaeozems (Anocolluvic) formed from silt loam and sandy loam occurred. The flat areas in the lower part of slope were covered with Mollic Gleysols formed from silt and silt loam. The average total amounts of macroelements were not high: Ca – 4.04g kg -1, Mg – 4.34g kg -1, K – 4.31 g kg -1, Na – 0.53 g kg -1, Fe – 19.05 g kg -1, Mn – 0.32 g kg -1 and Al – 20.22 g kg -1. These total amounts showed little vertical and horizontal variance in the soil profiles. The principal component analysis showed that the total amounts of elements in analysed soils was dependent mainly on sand and silt, and the similarity of soil horizons, in the cluster analysis, proves the translocation of macroelements was probable.

Opis:
This paper investigates the impact of Digital Terrain Model (DTM) resolution on the calculation of the sediment transport capacity coefficient LS within the Bystra catchment, employing various methods through GIS software. The study focuses on the significant role of GIS in environmental research and process modeling, emphasizing the relevance of LS coefficient analysis in morphometry, hydrology, and geomorphology, particularly in the context of agricultural soil erosion. The study presents results from calculating the sediment transport capacity factor LS using three methods for different resolutions (1, 5, 10, 30, 90 meters). LS coefficient determination relies on the catchment area map and slope map, the latter determined using two methods. The catchment area considered is that of the Bystra River, a right tributary of the Vistula, flowing through Nałęczów, Wąwolnica, Celejów, Bochotnica in the Lublin Province. Upon determining the LS coefficient, variations in results are observed, dependent on the chosen method. The discussion section highlights differences in LS coefficient maps based on resolution and method, with notable distinctions in the north-western part for a 10-meter resolution. Analyzing LS coefficient maps at different resolutions, the study observes variations in results based on the method employed. Higher LS coefficient values are noted in the river channel for a 1-meter resolution, attributed to factors such as river bed structure, building rocks, terrain slope, and climate. The conclusions emphasize the use of specific methods for determining slope rasters and highlight the Desmet and Govers method as yielding smaller variances in LS coefficient determination compared to other methods. The study recommends DTM models with resolutions of 1, 5, and 10 meters for LS modeling, considering their beneficial influence on variance and resolution. In summary, this paper contributes valuable insights into the influence of DTM resolution on LS coefficient calculations, providing a nuanced understanding of the interplay between methods, resolution, and terrain characteristics in the context of sediment transport capacity.

Opis:
Soil microrelief is one of the factors affecting wind and water erosion process. Spatial variability of soil surface (microrelief) influences initiation of the surface runoff and water flow mainly through depressions, where the runoff is delayed and infiltration increases owing to the interception of the flowing water. The research was conducted to assess the changes of relief of two soils (sandy loam and fine sand) under the influence of rainfall in a model experiment. The soil microrelief was determined by means of a contactless 3D scanner using the effect of line distortion as light beam illuminating the object surface (so called Moire pattern). On the basis of obtained results, maps of the differences in the scanned surface elevations were plotted in ArcGIS programme and the soil losses volume was computed. RR indicator calculated for sandy loam was decreasing with increasing depth of simulated rainfall. No such dependence was observed for loose sand.

Opis:
The construction of the Keuliling Reservoir aims to accommodate and utilise water for agricultural purposes. In this research, soil erosion modelling using the USLE method showed that the level of erosion hazard for each Keuliling Reservoir sub-watershed was classified into low-moderate. Land erosion occurred in the area around the reservoir inundation is the most significant contribution to the magnitude of erosion (38.62Mg∙ha-1y-1. Based on the point of sediment sampling in the Keuliling reservoir, the sediment volume was 1.43 Mg∙m-3. So, the volumetric sediment input from the Keuliling reservoir watershed is 20.918,32 m3∙y-1. The degradation of reservoir function due to sedimentation can affect reservoir services. The ability to estimate the rate of watershed surface erosion and sediment deposition in the reservoir is vital for reservoir sustainability. Besides the land erosion in the Keuliling Reservoir, there are also other potential sources of erosion that can reduce the capacity of the reservoir, i.e. the rate of sedimentation from a reservoir cliff landslide. The USLE estimation results show that the soil erosion analysis provides important and systematic information about nature, intensity and spatial distribution in the watershed and sediment volume in the Keuliling Reservoir. This finding allows the identification of the most vulnerable areas and the type of erosion dominant for long-term land management.

The paper presents potential soil erosion risk of the upper Parsęta catchment (Drawskie Lake District, NW Poland). The model considers following conditions affecting the size of soil erosion: slope gradient, LS factor, lithology, land use and land cover. Thematic maps have been reclassified into a 4-degree division. Potential soil erosion risk map was prepared on the basis of thematic maps. Areas with small and moderate susceptibility to soil erosion occupy 71.5% of the catchment area. The 4th class of erosiveness is represented by the river valley slopes, steep slopes of kame and moraine hills, covering 28.5% of the upper Parsęta catchment.

Soil erosion, gullying and landslides have been recognized as the major environmental threats in the Moldavian Plateau of Eastern Romania. Five stages of land degradation over the last two centuries can be depicted, namely:i) a preparing stage for future land degradation (1829–1999) when the most dynamic change of the native landscape was recorded; ii) a transitory stage (1900–1920) associated with the extension of the cultivated land up to 48% of the total area; iii) the climax stage (1921–1970) defined by both the traditional up and down hill farming and the peak rate of land degradation during 1960's; iv) a decreasing tendency of land degradation (1971-1990) as a result of the extension of conservation practices and the rainfall pattern; v) the present-day revival of land degradation associated to the Act no. 18/1991 when up and down hill farming under small plots is on the screen again. The main objective of this study was to define the process:based erosion and sedimentation by providing quantitative information from long-term field measurements in small catchments.

Ephemeral gullies most frequently form and develop on cultivated slopes in natural drainage lines or they are associated with man-made agricultural activities like field borders, furrows, tractor traces and cart roads. The paper presents the results of ephemeral gullies studies carried out in hydrological years 1998-2009 on cultivated slopes in the Wiśnicz Foothills. Ephemeral gullies usually form and develop during single rain or several subsequent rains of high erosivity (of several hundred MJ mm ha-1 h -1) on long cultivated slopes, particularly at the beginning of vegetation period, when most slopes are devoid of vegetation cover or plants are in the inicial stage of growth.

Opis:
Soil erosion is one of the most important phenomena affecting land composition and settlement. Among all natural causes of soil erosion such as rainfall intensity, temperature and wind, the human activity; massive deforestation and intensive agriculture, including the latest climate changes are considered as very important factors, especially nowadays. Thus, calculating the soil erosion coefficient appears very important in order to prevent the phenomena. Many methods are used to calculate such coefficient but in the presented research, the Erosion Potential Method was chosen. In this study, eight watersheds in southeastern Albania were evaluated. Results show that erosion is present in all considered watersheds. In one case (Panariti watershed) the erosion coefficient was very high; excessive, while in others it varies from heavy to very slight erosion. In conclusion, it can be stated that the Erosion Potential Method can be applied in the Albanian contest, same as in other neighbor countries. The results from Panariti, Roshani and Gianci should be further investigated due to the high quantity of soil eroded.

Opis:
Headcut erosion can severely accelerate soil loss in upland concentrated flows and lead to significant soil degradation in agricultural areas. Previous experimental work has demonstrated that actively migrating headcuts display systematic morphodynamic behavior, and impinging jet theory can provide an excellent theoretical foundation for this erosional phenomenon. This research sought to examine systematically the effect of an upstream sediment inflow on the morphodynamics of actively migrating headcuts in upland concentrated flows. Using a specially designed experimental facility, actively migrating headcuts were allowed to develop, and then subjected to an upstream sediment load composed of sand. As the upstream sediment feed rate increased, the size and migration rate of the headcut decreased markedly, but sediment discharge was less affected. The headcut erosion process was arrested as sediment inflow rates increased above a threshold value. As sediment feed rate upstream of the headcut increased, sediment size fraction downstream of the headcut also increased. This research suggests that headcut erosion can be greatly modulated by an upstream sediment source, further complicating the prediction of soil erosion on upland areas.

W pracy określono ilość erodowanej gleby metodą standardową, opracowaną przez Wischmeiera i Smitha, zmodyfikowaną przez Barriosa i zmodyfikowaną przez Jianguo Ma, na długości cieku głównego. Na podstawie wyników ze zlewni Bystrzycy Dusznickiej stwierdzono, że maksymalne natężenie erozji wodnej gleb występuje na terenach użytkowanych rolniczo. Wyniki uzyskane za pomocą omawianego modelu USLE (ang. "Universal soil loss equation") wg Barriosa różnią się o ok. 17% od uzyskanych z zastosowaniem pozostałych metod, co wynika ze sposobu obliczania współczynników L i S. Przeprowadzono również obliczenia, dotyczące wpływu zmian sposobu uprawy, z których wynika, że korzystniejsze jest wykonywanie zabiegów uprawnych (orki i innych) wzdłuż warstwic. Zmniejszyło to masę erodowanej gleby o 33% dla standardowej wersji modelu, a dla pozostałych metod o ok. 71%.
In this work the water erosion magnitude was estimated by the standard method developed by Wischmeier and Smith, modified by Barrios and Jianguo Ma on the length of the main watercourse. On the basis on the results for the Bystrzyca Dusznicka catchment it was found that the maximal intensity of the soil water erosion occurs in the agriculturally utilised land. The results obtained using the discussed USLE model (Universal soil loss equation) by Barrios differs from the values obtained using the other methods of about 17%. This is the result ofthe differences in methods for calculating the L and S coefficients. A simulation of changes of different kinds of land use has also been made. It was concluded that the most favourable is contour cultivation.

Application of a field experiment in soil erosion research in the Chwalimski Potok catchment (Drawskie Lakeland, upper Parsęta River)Stationary research upon soil erosion has been conducted in the Chwalimski Potok catchment since 2012 as a continuation of research started in 1994. In 2013 conducted two field experiments were conducted in order to evaluate the impact of high intensity rainfall on soil surface. The first experiment consisted of 5 and the second of 4 rainfall simulations. The rainfall was created by using a purpose-built rain simulator, consisting of 3 and 6 sprinklers placed around the testing plot. The paper focuses on the characterization of the course of these experiments. The achieved results compared with the results from the hydrological years 2012 and 2013 show that slope wash considerably increases during rainfall of high intensity and high amount.

Opis:
The integrated soil tillage developed in the Institute of Biosystem Engineering is based on a single pass of basic tillage, secondary tillage and sowing or planting. The integrated soil tillage enables to achieve a relatively high mechanical strength of the soil. An important element of the technology is the use of tillage roller sets which significantly influence the obtained aggregate structure and its eolic resistance. The aim of the study was to determine the influence of roller speed under various soil moisture conditions on the aggregate structure of the arable soil layer. The research was carried out on the production field in Dziećmierowo, Wielkopolska Voivodeship, Poland, on medium soil with the mechanical composition of light clay. During the research, cultivation sets with two units of Campell + Croskill platelet and studded rollers were used. For two actual soil moisture levels and five speeds within the range of 3–7 km/h, the influence of unit tillage energy at three levels of the cultivating layer (0–5 cm, 5–10 cm and 10–15 cm) was analyzed on the aggregate structure of soil and the content of aggregates with the highest resistance to wind erosion. The results of the work lead to the conclusions that it is possible to use the working speed and overloading of rollers set in integrated soil tillage trailer to manipulate the process of forming an optimal, erosion-resistant soil layer. However, it should be pointed out that for even very similar types of roller sets, the process control under different soil moisture conditions may be different and require an individual test.
