Applying the RUSLE and SEDD Equations to an Agricultural Watershed in Southwest Virginia - A Case Study in Sediment Yield Estimation Using GIS
… uses. The Revised Universal Soil Loss Equation (RUSLE) and the Sediment Distributed Delivery (SEDD) prediction models were used to determine the quantity of eroded sediment and the sediment yield at the duck pond, respectively. These models require numerous computations, which were performed at …

Alluvial Sedimentation Associated with Logging in Low Gradient Watersheds in DeSoto National Forest, Mississippi
… Using the Revised Universal Soil Loss Equation (RUSLE) to model and predict sediment erosion, and the use of historical aerial photographs to determine exact locations of forestry removals, the RUSLE model predicted 10 times more erosion during periods of logging compared to natural conditions. …

Characterization of Watersheds on Fort Benning Military Reservation: Comparison of Field Data to Watershed Parameters
… a modified revised universal soil loss equation (RUSLE) to create a soil erodibility index map. Wolman Pebble Count data showed that in half of the watersheds, 84% of the sampled grains were less than half a millimeter in size. Watersheds studied were dominated by Nankin sandy clay loam soils, …

Estimating Sediment Losses Generated from Highway Cut and Fill Slopes in the Lake Tahoe Basin
… Basin. The Revised Universal Soil Loss Equation (RUSLE), Tahoe Basin Sediment Model (TBSM) and the Road Cut and Fill Slope Sediment Loading Assessment Tool (RCAT) are the most common soil erosion models used to predict sediment yields from disturbed slopes in the Lake Tahoe Basin; however, limited …

Evaluación del proceso de erosión hídrica en laderas bajo diferente sistema de cobertura vegetal en el municipio de Santa Lucia, Boaco, 2008
… Ecuación Universal de Pérdida de Suelo Revisada (RUSLE) y ecuación de perdida de suelo (USLE). Los resultados obtenidos determinan que la cubierta de pasto nativo (sin mantenimiento agronómico) fue el que presento las mayores pérdidas de suelo de 8.257tn/ha y de escurrimiento superficial de 46.71 …

Evaluación del proceso de erosión en laderas bajo diferente sistema de cobertura vegetal en el municipio de Boaco 2008
… suelo y la ecuación universal revisada (USLE y RUSLE). Los resultados obtenidos determinan que la cubierta vegetal de pasto para el ciclo de primera fue la que presentó el menor promedio de pérdida de suelo y escurrimiento superficial con 5.93t/ha y 122.71 m³/ha seguido de frijol con 9.06 t/ha y …

Analysis and visualisation of digital elevation data for catchment management
… using NEXTMap and OS 50 data with SCIMAP and RUSLE modelling techniques. Findings from the research demonstrate that a number of nationally available DEMs in the UK are simply not ‘fit for purpose’ as far as local catchment management is concerned. Results indicate that DEM source and …

Soil erosion and conservation potential of row crop farming in mountainous landscapes of South Korea
… with the Revised Universal Soil Loss Equation (RUSLE). We found that organic farming reduced erosion for radish, as a result of an increased weed biomass due to the absence of herbicides, but that it increased erosion for potato due to lower crop coverage, presumably as a consequence of …

Identifying targets for multifunctional perennial cropping systems implementation through a landowner adoption preferences survey and a spatial suitability analysis
The demand to meet food security goals drives production of modern row-crop agriculture to areas of marginal land. Intensive management of marginal cropland accelerates instances of soil erosion and nutrient leaching. Multifunctional land use strategies are needed to mitigate environmental impacts …
