Abstract

In order to evaluate the effects of 3 land-use/land cover practices on runoff and sediment yield using runoff plots and 2 models : Water Erosion Prediction Project (WEPP) and Erosion 3D, runoff plots were established at 3 sites in the Mara River basin : Amala upstream; Amala downstream and Nyangores watersheds. In all of the 3 watersheds, 3 land uses (cropland, grassland and bare land) with similar slope steepness and soil types were considered. The plot scale research results indicated that erosion was high in all of the sites on cultivated lands. The model evaluation indicated that both of the models perform well in estimation of runoff, however, the WEPP model performs better than Erosion 3D in estimation of soil erosion
