Abstract

It is very important to recognize the areas with high potential risk of LANDSLIDE in order to resist that. In a case study, thirty three LANDSLIDEs have been observed in Safarood watershed. The purpose of this study is to recognize factors and ZONATION of potential areas for LANDSLIDE. This paper covers specific factors including lithology, fault, height, slope, direction, rainfall, soil, vegetation and villages of the area. GIS is used to prepare and integrate thematic layers, combine them by weight model and finally to prepare a map of LANDSLIDE hazard. AHP statistic method is used for weighting the criteria. The criterion for weighting the existing elements in each layer has been based on the most important role played in the layer and in LANDSLIDE. after combining various layers in GIS medium, the map of LANDSLIDE hazard ZONATION is obtained in four ZONATION with every high hazard, high hazard, medium and low hazard. It has been determined that approximately 31% of the surface of the area is encountered very high and high hazard LANDSLIDEs. 94% of the cases observed in LANDSLIDE, based on the mentioned ZONATION and the model, are in the ZONATION of very high and high hazards that show the high accuracy of this method.
