Abstract

ENVIRONMENTAL HAZARDS are considered as one of the factors threatening human societies.Identification areas susceptible LANDSLIDES risk assessment of natural hazards and management of are the essential steps in the city's watershed. The purpose of this study is LANDSLIDES hazard zonation in IZEH URBAN WATERSHEDS of East Khuzestan. In this research First, eight layers effective in LANDSLIDES, including: geological formations slope, elevation, rainfall, distance from drainage, land use, slope and distance to faults in ARC GIS digital and were classified, Then using CRITIC were weighted layers. The next step was to standardize layer using fuzzy function; and were imported the models. Finally LANDSLIDES hazard zonation maps by using two models of multi-criteria models (TOPSISS, and WLC) were prepared. These maps are susceptible to LANDSLIDES Each of those class into five regions with very low to very high risk were. Classified. The results of models show that for TOPSIS 122.99 km from the area is high to very high risk and 89.5 km very low to low risk is. While WLC model 76.13 km from region in high to very high and143.03km in low to very low risk class. Comparison of the models shows that the TOPSIS model is more zones at risk earthquake is show. According to the field research and studies in the IZEH area seems WLC model is closer to reality. Consequently WLC model has perform better than TOPSIS model for landslide hazard in this region.
