Distributed Watershed Runoff and Sediment Production Model

A distributed watershed runoff and sediment production model, reflecting the influences of the spatial inhomogeneity of underlying surfaces and human activities on watershed runoff and sediment production, is constructed. It can simulate the spatial and temporal processes of runoff and sediment production under different kinds of land utilization, and provide technological support and scientific basis. Taking Chabagou watershed as a case, its simulated results are satisfactory.
