Abstract
Preparing landslide zoning maps is of great help to land planners and engineers in selecting the appropriate location for implementing development plans. Since predicting the time and location of landslide occurrence is not possible preciously, so slopes are concerned with zoning the risk of landslides. The aim of this research is to identify landslide-prone areas using analysis hierarchy process (AHP) methods in Haftkel County. The geology of the region shows that Quaternary alluvium and the Gachsaran Formation are the most influential factors in the creation of landslides in the area. The importance of elevation is in creating steep slopes and surfaces increases with increasing slope. The distribution of slope depends on the outcrop morphology of the region, and the slope angle of the slopes determines the characteristics of the region. The possibility of landslides also increases with increasing slope angle. The most slope movements occurred at slope angles of <45 and 36-45 degrees, and the least possibility of landslides occurred at angles of less than 15 degrees. In general, it can be concluded that the most effective factor in causing landslides is the lithology factor.
