| Summary: | The indication of the potential landslides in the area which due to geographical condition and the construction of human is prone to landslides is necessary, Ghalah Chai dam is one of these areas .In this study Analytic Network Process (ANP) Was Valuated .For this study the Image TM, 2011 Landsat was used. The maps of effective factors of landside (slope, aspect, lithology, land use, distance to fault, distance from river, distance from roads, elevation) were prepared in the GIS environment. Afterward it was crossed by the layer of sparseness of landsides and the hazard zoning maps of landside was produced in the above mentioned methods. The results showed that among eight factors effective factors, landuse, Aspect and Elevation have a greater role in the occurrence of landslides. Also comparison of the degree of fit between landslide distribution and zoning map of the mentioned method showed that, the analytic network process with 67/33% fitness better performance in identi fying risk areas in the study area. |
