Landslides cause damages and harms to human lives. Proper analysis and suitable modeling of these dangers may reduce relative losses. It even prevents mass movements. The Zab river basin is susceptible to landslide. To evaluate the landslide risks in the study area, analytical hierarchy process (AHP) method and geographical information systems (GIS) as well as local data were used. The local data includes: slope, slope aspect, distance to road, distance to drainage network, land use and land cover, geological factors, geomorphologic characteristics and climatic condition of area. The use of AHP model resulted in providing a real country image indicating initial susceptibility to the landslide. Based on findings southern basins are most susceptible to landslide.
