Exhaustion and steady state models for predicting landslide hazards in the Canadian Rocky Mountains

Abstract The temporal distribution of landslides can be evaluated by steady-state and exhaustion models. The probability of landsliding remains constant through time in the steady-state model but the probability decreases in the exhaustion model as more slopes fail. Rock sliding down bedding surfaces on overdip slopes exhausts hazardous sites to leave stable dipslope landforms in Kananaskis Country in the Canadian Rocky Mountains. The distribution of rock slides in this area can be better explained by the exhaustion model than by the steady-state model.
