Abstract

The purpose of this study is to produce the LANDSLIDE susceptibility zonation map for POULROOD earth fill dam reservoir with using AHP/Fuzzy method. To obtain the Fuzzy relations for producing the susceptibility map, a LANDSLIDE inventory database is obtained by both field surveys and desk studies. To produce susceptibility map with user define and Gaussian functions then LANDSLIDE related factors such as litology, distance from faults, distance from drainage, slope angle, slope aspect, slope curvature, distance from road, NDVI, earth quick horizontal acceleration and Precipitation were used in the LANDSLIDE susceptibility analysis. The results obtained in this study showed that the frequency ratio can be used as a simple tool in assessment of LANDSLIDE susceptibility when a sufficient number of data were obtained. According to LANDSLIDE susceptibility index for different factors, it was found that the aspect, lithology and drainage system are the most effective factors in the study area. The prediction performance of the susceptibility map is checked by considering quality sum amount. With investigation get amount of quality sum index for two types function in FUZZY MULTI CRITERIA DECISION ANALYSIS and attention to good work of operator Gamma in LANDSLIDE susceptibility mapping, is produced map with user define function and Gamma0.95 operator having topmost quality. The results obtained also showed that the user define function is more reliable then Gaussian function in the study area.
