Application of the analytical hierarchy process (AHP) for landslide susceptibility mapping: A case study from the Tinau watershed, west Nepal

Landslide problems are abundant in the mountainous areas of Nepal due to a unique combination of adverse geological conditions, abundant rainfall and anthropogenic factors, which leads to enormous loss of life and property every year. To control such problems, systematic studies of landslides are necessary, including inventory mapping and risk assessment. This study applies the analytical hierarchy process method in the Tinau watershed, Nepal. A landslide susceptibility map is prepared on the basis of available digital data of topography, geology, land-use and hydrology. The landslide susceptibility map is validated through physical and statistical methods. The results reveal that the predicted susceptibility levels are found to be in good agreement with the past landslide occurrences, and, hence, the map is trustworthy for future land-use planning.
