The comparison analysis between two infiltration numerical models

The slope satiability analysis depends on its seepage simulation, and the rainfall is one of the most important factors which affect the seepage of soil slope. When the rainfall intensity is large, the runoff occurs and affects the seepage. There are two methods to simulate the slope seepage under rainfall condition. One is using seep and runoff coupled model, and another is using seep model which ignores runoff. Two methods are compared in this paper, and the influence degree of runoff to seepage is researched. Calculation results show that the difference is not significant between considering or ignoring runoff under the situation presented in the paper.
