Rainfall and streamflow are two most important factors of soil erosion that transports the soil particle from one place to other place, than deposits occur. According to the dynamic of land cover, causes decreasing or increasing streamflow and sediment yield. Therefore, the Du watershed was selected as the study area to understanding how can landuse types affect on dynamics of streamflow and sediment yield. Thus, the SWAT （soil and （?）ater assessment model） model is a hydrologic model interface ...
