Abstract :
Sorkhab basin that is one of the sub basin of Sezar river is located in middle of Zagrossmountain in lorestan province. The most important characteristic of this region ismountainous quality with compress mountain and deep valises. The slope of this regionare suitable for mass wasting because of its inherent characteristics and exiting of naturalhumanfactors. The aims of this research is the zoning of land slide potential risk inSorkhab basin and recognition of some effective factors for this phenomenon. To obtainfor this purpose the role of many factors such as: lithology, digital elevation model, slope, aspect, distance of fult,landuse, annual rainfall,freezing days, temperature oscillation andisoseismic on the Sorkhab basin have been analysis and the result of that has given asweight model. According to the finally results, high risk almost 35% and with totalmiddle risk , mass wasting threat mire than half if this area
