The aim of this study is assessing and mapping landslide susceptibility in watershed of semiarid mountain areas. Saeedabad-chai Watershd is located on the northwest of Iran and the North of Sahand Mountain. This study is using Bivariate Statistical Analysis (BSA), weights-of-evidence (WOE),GIS. The results of this assessment show that causative factors as slope (âwÆ= + 3.965), landuse(âwÆ= + 0.759), distance of road(âwÆ= + 1.498), lithology (âwÆ= + 0.424), rainfall (âwÆ= + 0.388), distance of rural (âwÆ= + 0.161) play a major role in the landslide occurrence.There is a negetive relationship between landslides and distance of fault (âwÆ= - 0.006) and distance of channel (âwÆ= - 0.325) in the Saeedabad-chai Watershd. The medium, high and very high susceptbility zones make up 43.116 % of the total study area. The acuuracy of the map was evaluated by( Li) index. This index shows that 92% of landslides occure on medium, high and very high susceptbility zone.
