The stability of a slope subjected to rainfall events of increasing intensity and decreasing duration is analyzed with FLAC. The apparent cohesion provided by capillary forces in unsaturated soil is simulated using the two-phase fluid flow logic. As soil saturation increases, soil cohesion can decrease and result in slope collapse.
