Abstract: The simulation of the subsurface and surface flow is based on easch other under rainfall conditions; a coupling method is used to solve the problem accurately. The subsurface and surface flow coupling equation is formed and its computer program is compiled using the FEM. A method is presented to speed the convergence and to judge the saturation of the surface. The simulation results show that the speed convergence is feasible and very fit for the real phenomenon in the nature. It is helpful to analyze the reason for rainfall-induced landslides.

Key words: rainfall, runoff, infiltration
