A physically based slope stability model combined with a hydrological model was applied to a 350-km2 area in Dhading district, Nepal. The study identified shallow landslide-prone areas based on topography, land use, and soil types. Only 29% of the soils were found to be stable, with 25% being unstable under fully saturated conditions. The infiltration-based method proved more reliable. This methodology, using basic GIS data, could be valuable for predicting regional landslide susceptibility in remote areas with limited information.
