Potential landslide-prone areas in the Kelara sub-watershed using the analytical hierarchy process method

Abstract

Landslides are one of the geomorphological processes active in changing the shape of the earth's surface. Landslides have an impact on life and the environment. This research will map the potential landslide-prone areas in The Kelara Sub-watershed using the Analytical Hierarchy Process (AHP) method. The method used in this research is the Analytical Hierarchy Process (AHP) method and the spatial analysis method. The potential for landslide-prone areas in The Kelara Sub-watershed has three potentials or levels of landslide vulnerability, namely low (2939.28 ha) (32.72%), medium (3082.78 ha) (34.32%), and high (2961.55 ha) (32.96%). Parameters that influence landslides in the Kelara Sub-watershed are slope parameters with a weight of 0.30 or a score of 30%.
