Landslide hazard zonation using GIS: A case study from Sindhupalchowk, Nepal

Abstract

Landslides are instant event of mass movement of earth surface down a slope, causing loss of life and property in hilly region of Nepal. Considering the recent massive landslide event, development of the landslide hazard map of Sindhupalchowk district was done using different weighted controlling factors i.e. slope, relative relief, distance to road & river network, landuse and soil maps. Landslide zone of low, moderate, high and very high hazards were derived and found that around 40% are in high hazard prone areas. Prior identification of hazard area could mitigate future loss events.
