[1] Soil erosion models are usually limited in their application to the field scale; however, the management of land resources requires information at the regional scale. Large‐scale physically based land surface schemes (LSS) provide estimates of regional scale hydrologic processes that contribute to erosion. If scaling issues are adequately addressed, coupling an LSS to a physically based ero...

There is a need in many emerging nations to develop simple methods for predicting areas of extensive soil erosion using imprecise, but real-world, input data at low cost with considerable Ž . accuracy. The objectives of this study are to 1 develop fuzzy logic models that predict soil Ž . erosion in a relatively large watershed using a limited number of input variables, 2 determine the Ž . effec...

evaluation of sediment yield in watershed scale is considered so important for implementation of soil conservation, watershed management, environment, dam construction and water resource management. using empirical model is one of the approaches of evaluating sediment yield. this research in kasilian watershed evaluates sediment yield by using geomorphology method and epm model with arc view gi...

mpsiac is currently known as an appropriate method to measure sediment ofwatershed basins of the country while there has not been any sensitivity analysis so far forthis method. in this study, required data for mpsiac model were gathered from six basins;amame-kamarkhani, kand-golandok, tang kenesht (from two different references), nojian(from three different references), pegahe sorkh katvand (f...

Semiarid landscapes are characterized by vegetated surfaces. Understanding the impact of vegetation on aeolian soil erosion is important for reducing soil erosion or limiting crop damage through abrasion or burial. In the present study, a saltation model fully coupled with a large-eddy simulation airflow model is extended to vegetated landscapes. From this model, the sensitivity of sand erosion...
