| Popis: | Growing population and expansion of settlements over hilly areas have largely increased the impact of natural disasters such as landslide. This paper deals with the use of Geographical Information System (GIS) and Multi-criteria Decision Making (MCDM) technique to map the landslide hazard zones. For this study, ten (10) landslide inducing parameters are considered. Analytical Hierarchical Process (AHP) and rating method are used to determine the weights for each of the parameters used. Two (2) different models which consider different parameter combinations developed by the authors are used. Results obtained are compared to landslide history and the accuracies for the two models i.e. Model 1 and Model 2 are 72% and 64% respectively. |
