Mass Movements Hazard Zonation with Analyzing Hierarchy Process (AHP)Method (Case Study: Karaj Dam basin)

This article aiming to identify the factors affected on creating the phenomenon of landslide, to specify areas with zonation and potential landslide in the basin Karaj Dam was performed by Hierarchical Analysis Process(AHP) . At first the most important factors a factors affecting landslide were prepared. Then landslide map was prepared with using aerial photos with scale of 1:50000 in 1957 and 2003, and field checks with using GPS. Then affecting factors were binary compared using surveying satellite images analyzing method determined the weight of each factor as indicator for their amount effects. Accordingly, the landslide zonation hazard map was prepared in different sensitivities. Results of this study are showed that most recorded landslides in this area there are in the high sensitive zone marked by offered model.
