Description :
To investigate the stability of complex hillslopes (with different slope curvatures and plan shapes), the AA. combine the hillslope-storage Boussinesq (HSB) model with the infinite slope stability method. The resulting hillslope-storage Boussinesq stability model (HSB-SM) is abble to simulate rain-induced shallow landsliding on hillslopes with non-constant bedrock slope and non-parallel plan shape. The AA. apply the model to 9 characteristic hillslope types with 3 different profile curvatures (concave, straight, convex) and 3 different plan shapes (convergent, parallel, divergent). The results show that the presented dynamic slope stability model (HSB-SM) can be used safely for slope stability analysis on complex hillslopes.
