CHASM™ team

CHASM is an integrated slope hydrology/slope stability software package that aids the assessment of slope stability conditions. It is designed to help the user estimate the effects on slope stability of selected storm events, surface covers, slope plan curvatures and other important slope and material properties.

The dynamics of slope hydrology are computed using a finite difference formulation that accommodates unsaturated and saturated soil water conditions. The stability analysis (Janbu and Bishop methods in UNIX and Bishop in Windows) is undertaken using a grid search procedure, which is implemented continuously during the simulation period.
