Severe lack of data on soil erosion and sedimentation in many national watersheds requires the application of appropriate empirical methods for their estimation. This study is aimed to evaluate the efficiencies of Universal Soil Loss Equation (USLE) and some of its variations including MUSLT, MUSLE-E, MUSLE-S and AUSLE in semi-arid climates. This study was undertaken on standard plots in the ra...

The focus of soil erosion research in the Alps has been in two categories: (i) on-sitemeasurements, which are rather small scale point measurements on selected plots often constrained to irrigation experiments or (ii) off-site quantification of sediment delivery at the outlet of the catchment. Results of both categories pointed towards the importance of an intact vegetation cover to prevent soi...

Sediment is one of the important natural resources on Earth. Information sediment key to making decisions regarding soil management and mitigation during hazard events. Thus, this research analyzed mapped benefit-cost ratio (BCR) in Ping River using a Geographic System (GIS). Furthermore, benefit was new application Revised Universal Soil Loss Equation (RUSLE) with spatial resolution 1 km2. The...

Intense soil erosion in the northern part of Gerecse Hills, Hungary, is causing significant damage to vineyards area. Three Neszmély Wine Region were investigated quantify amount eroded soils. The method was based on monitoring for one-year between July 2019 and June 2020. Every season, a set photographs taken from an unmanned aerial vehicle. images processed photogrammetric workflow produce hi...

Soil erosion is one of the major environmental problems in terms soil degradation Shirvan plain Republic Azerbaijan. leads to significant on- and off-site impacts such as decrease productive capacity land sedimentation. The key aspects influencing quantity mainly rely on vegetation cover, topography, type, climate. This research studies quantification under different levels data availability pl...

Tillage erosion is considered a major contributor to total soil besides water erosion. However, tillage has been neglected in Czechia. Therefore, our main goal was analyse and compare the effect of with that The combined both types modelled at high spatial resolution. Universal Soil Loss Equation approach used calculate erosion, while model (diffusion approach), which takes into account slope c...

Soil erosion is a major factor leading to dams’ siltation and reducing their storage capacity. This study mapped the hot spots of soil areas predict erosion/siltation in Ghiss basin/dam (northeastern Morocco). In this context, various data has been prepared geographical information system for estimation by integrating universal loss equation (USLE). The result revealed that rate ranges between0...

Abstract Soil erosion and sedimentation are among the most crucial environmental hazards that arise from urban development. The Geographical Information System (GIS) based method is proposed to demonstrate for identification of sediment source areas prediction storm yield catchments. gross soil was calculated by using revised Universal Loss Equation (RUSLE). In general, loss river basins at Ked...

ABSTRACT The study aimed to identify and evaluate the spatial variability in laminar erosion areas using precision agriculture tools. Soil data from three properties western region of Paraná state, Brazil, were used: one municipality Céu Azul (area A) two Serranópolis do Iguaçu (areas B C). To discrepant (outliers), analysis dispersion quartiles was performed a box-plot graph. Data normality ve...

The effect of soil surface roughness on runoff and sediment production is an area not yet fully quantified. Current erosion prediction models, such as the Revised Universal Soil Loss Equation, predicts a reduced erosion from an increased soil roughness, without considering the functionality associated with different roughness forms. In this research, we used a mechanistic approach in which soil...
