Slopes are vulnerable to landslides, particularly under the process of infiltration. Considering the process of infiltration, we produced a modified Green-Ampt model, in which the new parameter of water content at the wetting front was introduced. We experimentally determined this parameter, which proved to be a constant and with ponding water was 1.7 times higher. We combined the improved model and experiments with a traditional limit equilibrium method, and this simplified method was applied to calculate a safety factor, which can be used to dynamically evaluate the slopes and provide new insights into design.
