Abstract :
Based on the studies to the erosion mechanics of slope and rill, the basic problems and computation methods are discussed on the erosion simulation. Some new modes in computation of channel deposition and restarting are derived. The key links and impact factors to watershed erosion and sediment transportation are analyzed. A mathematic model has been built to simulate small watershed erosion and sediment yield. The model was verified by Lizixi basin and got good results.
