Landslide susceptibility mapping using fusion models of frequency ratio (FR) and Analytical Hierarchy Process (AHP)

Landslide susceptibility zonation mapping is necessary in urban and rural development planning. So far different methods are presented for Landslide susceptibility zonation. In this study، using statistical method of Frequency ratio and Analytical Hierarchy Process (AHP) based on paired comparison and intervention based such as slope، aspect، altitude، geology، land use، Normalized vegetation index (NDVI)، curvature and the linear elements waterways، road and fault، landslide susceptibility map was prepared as part of the Talar watershed in the Mazandaran province. Results showed that 35/78% of the area has low Susceptibility، 38/05% of the area has moderate Susceptibility، 22/14% of the area has high Susceptibility and 4/03% is a very high Susceptibility area.
