Water erosion prediction using Revised Universal Soil Loss Equation and GIS: A case study of Gorganrud Basin
Soil erosion and sedimentation processes can be considered as serious eco-environmentalproblems. This study aimed to estimate the basin-wide erosion using the Revised UniversalSoil Loss Equation (RUSLE). The soil erosion parameters included rainfall erosivity mapgenerated from the rainfall data, soil erodibility extracted from the soil map, land cover andmanagement map produced from supervised ...
متن کاملSpatial Variability of Soil Erosion and Soil Quality on Hillslopes in the Chinese Loess Plateau
Soil erosion rates and soil quality indicators were measured along two hillslope transects in the Loess Plateau near Yan'an, China. The objectives were to: (a) quantify spatial patterns and controlling processes of soil redistribution due to water and tillage erosion, and (b) correlate soil quality parameters with soil redistribution along the hillslope transects for different land use manageme...
متن کاملSpatial Analysis on Surface Deformation by Soil Erosion in the Chinese Loess Plateau Using Insar Techniques
Monitoring the surface deformation over the loess hills could help us understand the dynamics of soil erosion, the extent of anthropogenic impacts, and the mitigation methods for the potential damage to local ecosystems, agricultural production, socioeconomic infrastructure, water quality, and air quality in the Loess Plateau and the surrounding areas. The objectives of this study were to compr...
متن کاملRegional Evaluation of Soil Erosion by Water: A Case Study in the Loess Plateau of China
Astract: This paper shows how recent situation of soil erosion evaluation and prediction on a regional scale based on the techniques of spatial information. The study, which was carried out in central China, identified sediment discharge, precipitation, soil composition, gully density and land use as erosion factors at the regional level. It showed that soil erosion can be assessed and predicte...
متن کاملAssessment of Soil Erosion Susceptibility in Kothagiri Taluk Using Revised Universal Soil Loss Equation (RUSLE) and Geo-Spatial Technology
Soil erosion is a serious environmental problem in Kothagiri Taluk. Many studies have been carried out to map shifting cultivation and areas susceptible to soil erosion. Mostly, estimated soil loss is taken as the basis to classify the level of soil loss susceptibility of area. The Revised Universal Soil Loss Equation (RUSLE) function is a commonly used erosion model for this purpose in Kothagi...
