Rain-induced landslides normally involve water infiltration into unsaturated soils. Unsaturated soils have high cohesion which implies the presence of tensile stress in the soils. Hysteresis (i.e., wetting and drying) is a common feature of unsaturated soils and it is expected to have some influence...
