Predicting Soil Erosion With RUSLE in Mediterranean
Accurate assessment of soil loss is essential for sustainable agricultural production, 11 management and conservation planning, especially in productive rain-fed agro-ecosystems 12 and protected areas. The European Union considers soil as a non-renewable resource and 13 identifies that soil degradation has strong impacts on soil and water resources. In this work the 14 Revised Universal Soil Lo...
متن کاملModeling Soil Erosion Using Rusle and Gis Tools
Soil erosion involves detachment and transport of soil particles from top soil layers, degrading soil quality and reducing the productivity of affected lands. Soil eroded from the upland catchment causes depletion of fertile agricultural land and the resulting sediment deposited at the river networks creates river morphological change and reservoir sedimentation problems. However, land managers...
متن کاملEstimation of Soil Erosion Using RUSLE Model and Determination of Direct and Indirect Damages in Kan Watershed
Prioritization of different regions at watersheds based on the erosion rate and sediment yield with approach of its economic effects can lead to the production of valuable information for projects of soil conservatism. The present study aim was sub-watersheds prioritization of Kan watershed based on erosion condition with the approach of economic losses from erosion and sediment. Therefore, the...
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...
متن کاملPredicting soil erosion in conservation tillage cotton production systems using the revised universal soil loss equation (RUSLE)
Despite being one of the most pro®table crops for the southeastern USA, cotton (Gossypium hirsutum L.) is considered to create a greater soil erosion hazard than other annual crops such as corn (Zea mays L.) and soybeans (Glycine max (L.) Merr.). Reduced tillage systems and cover cropping can reduce soil erosion and leaching of nutrients into ground water. The objectives of this study, which wa...
