Factors that control the stability of mountain slopes may be in a tenuous state of equilibrium that can easily be upset by timber harvesting, vegetation conversion, and road construction. Shallow, rapid landslides are the dominant erosion and sediment delivery mechanisms in much of the steep terrain worldwide, especially where rainfall is high. Deep and dense tree root systems often contribute the additional component of soil shear strength necessary to insure long term stability of steep slopes. Road and foot paths may redistribute water onto marginally stable hillsides or hollows, promoting slope failure. Here we present a distributed shallow landslide model that captures the temporal dynamics of imposed management scenarios at the catchment scale. This physically-based model incorporates a planar infinite slope analysis module (based on factor of safety analysis), a kinematic wave groundwater module, and a module for continuous temporal changes in root cohesion and vegetation sur...
