MATHEMATIC MODEL OF RUNOFF AND SEDIMENT YIELD BY SLOPE EROSION UNDER RAINFALL

LIU Yang 1, WANG Xi kui 2, PENG Ze zhou 1 (1.College of Geo Exploration Science and Technology, Jinlin University, Changchun 130026,China;2.College of Earth Sciences, Jilin University, Changchun 130026,China)  
The mathematic model include slope water continuous equation, water kinematical equation, silt continuous equation, slope surface deformation equation. Considering the velocity of the water streams and the nonlinear equation, facing wind finite difference method being used to solve the equation, and a program was written out. Our research can describe the slope erosion situation trends, and expand to whole watershed, which can provide important basis for administering water and soil erosion.
