Abstract :

Landslides are one of the most destructive phenomena of nature that cause damage to both property and life every year, and therefore, landslide susceptibility zonation maps are needed for future developmental activities ;Nevertheles , due to complex nature of landslides, usually,a reliable susceptibility map could not prepared by a simple method. For this reason, many procedures have been used to produce such maps. Using Anbalagan Sets to produce a landslide susceptibility map of viliage valdian aria in 1:250000 scale is the main purpose of the present study. Geology, slope angle, rainfall, earthquake and slope aspect were considered as the main landslide factors in the study area. According to produced map, about 9% of the study area is classified as very high susceptibility and about 33% as high susceptibility area. The sudy shows the high sensitivity of viliage valdian aria to slope instability.
