摘要: Landslides form major natural hazards in hilly terrain the area, and caused extensive damages to road, human dwellings agricultural lands. There is still a great danger of further landslides region. Therefore, it important prepare landslide susceptibility map In this study Yadak-Tevil watershed was prepared using Analytical Hierarchy Process (AHP) with help GIS. For purpose, thematic layers including inventory, lithology, distance from drainage, slope, slope aspect, elevation were main contributory factors be considered for zonation. The classified into four different classes. classes are: low 16.13 % (33.50 km2), moderate 33.34 (69.38 high 33.00 (68.68 very 17.53 (36.48 respectively. Results show that AHP method precise evaluation potential due use binary comparison affecting considering numerous at same time other prevalent method.
