摘要:The aim of this research is to estimate surface runoff and sediment yield for all ungaged wadi inflows to Mosul Lake, the regulating lake of the Mosul dam, Iraq. These processes, which affect the live storage of the lake, are estimated using a combination of three computer methods. The first is to convert physical basin maps to digital maps by using GIS methods with satellite images and remote sensing information. The second method delineates the basin boundaries and morphological characteristics and simulates runoff for basins using the Watershed Modeling System. The third method is to estimate the sediment yield using the assumptions of the modified universal soil loss equation under single storm rainfall by applying spatial programs together with programming. The field work consisted of soil tests and surveying cross sections along the lake to compare with the initial cross sections when the reservoir was filled. Sediment yield and accumulation affect the operation of the power station and also the regulation of the releases to the Tigris river. They also determine the life of the project as dead storage diminishes over time.
