Details and Description: 

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.
