Earth dam is always a safety issue, as it can experience catastrophic destruction due to the slope failure caused by various factors, such as water content increasing in earth slopes, vegetation root decay and so on. This study is to investigate the variation of hydrological processes in the saturated and partially saturated slopes with a new simulation program PCSiWaPro® (a computer aided leachate forecast tool) under transient boundary conditions. The integration of a weather generator inside the PCSiWaPro® allows a transient water flow calculation with respect to atmospheric conditions (precipitation, daily mean temperature and sunshine duration) and removal of water by plant roots and leaves. The simulation results of one scenario in a Chinese earth dam clearly demonstrate a good applicability of the program PCSiWaPro®.
