Slope stability software
CHASMTM 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) is undertaken using
a grid search procedure, which is implemented continuously during the
simulation period.
CHASMTM has been used in St Lucia and is an appropriate model for the MoSSaiC project - road cutlopes, urban slopes and agricultural slopes can all profitably be analysed using this software.
