GIS-based landslide susceptibility mapping of Bonab city, NW of Iran by using fuzzy AHP

Abstract

The presented study is attempted to investigate the landslide susceptibility of the Bonab city located in Urmia lake basin in East-Azerbaijan, NW of Iran. As methodology the coupled method contain analytical hierarchy process and fuzzy logic, named FAHP was applied to risk-ability evaluation and prepares sliding potential maps. For this purpose, three main triggering factors identified for the susceptibility assessment which is classified as geomorphology, geology and human activities where each class has several sub-classes. According to the landslide susceptibility assessment and zonation map, the main risk zone is located in east to southeast part on the Bonab city in Malekan-Bonab highway route.
