Abstract

LANDSLIDEs are natural HAZARDs that cause financial and life damages. Identification of regions having potential for LANDSLIDE occurrence is one of the basic measures in natural resources management which decreases damages caused by these phenomena. For this purpose Different LANDSLIDE HAZARD ZONATION models were proposed based on the environmental conditions and goals. The Moalemkalayeh Watershed with area of 723.4 km2 is highly susceptibility to mass movement occurrence. Mass movement inventory map (1: 50000) was prepared using stereoscopic interpretation of vertical aerial photographs and field checks.448 mass movements were identified.50 mass movements were chosen by randomly and the effective factors on mass movement occurrence were identified. Geology, slope, aspect, fault, road, river, elevation, land use and rain factors were identified as effective factors. Information layers of nine factors in Arc- GIS environment were prepared. These layers were crossed with Inventory map and the CF of nine layers were computed then LANDSLIDE HAZARD ZONATION map was provided based on Certainty Factor and. The applicability of this map was investigated with correlation coefficient and process of HAZARD classes distribution. Results showed that CF model is the suitable model for the Moalemkalayeh watershed.
