Landslides are complex hazardous phenomenon occurring in nature due to interaction of nature’s forces like rainfall infiltration, seismic activities etc with the soil Skelton or due to unmanaged human exploitation of soil resources for construction purposes. Landslides can cause damage to human life and infrastructure, the magnitude of damage depending upon spatial, geological and morphological aspects of vulnerable soil slopes. Mitigating the damaging effects of landslides becomes necessity and an Early Warning system based on evaluation of interaction of geotechnical parameters of soil slopes with those of rainwater infiltration at the time of trigger comes into picture. While the conventional stability analysis approaches are not convincing, for real time assessment of potential instability, concepts of unsaturated soil mechanics forms a strong basis especially for rainfall induced landslides. This paper reviews some of the fundamental geotechnical aspects for risk assessment of rainfall induced landslides.
