Abstract

In this study LANDSLIDEs occurred in a part of Haraz watershed were determined using aerial photos and field studies, then LANDSLIDE hazard zonation using geomorphological factors (slope, aspect and elevation) and geological factors (lithology and distance fault) as the most important effective factors on LANDSLIDE hazard. So each of the effective factors and information layer and is ILWIS environment for analysis based on fuzzy set theory using MATLAB 7.1 software before that MEMBERSHIP FUNCTIONs were determined for each effective element on LANDSLIDE. Then output this software that computed hazard for each pixel in case study map transform to ILWIS software environment and LANDSLIDE hazard zonation was made using fuzzy Gaussian and Triangular MEMBERSHIP FUNCTIONs. Evaluation results showed that LANDSLIDE hazard mapping using Gaussian MEMBERSHIP FUNCTION QS (0.23) is more accuracy and exact in comparison with map was made by using triangular MEMBERSHIP FUNCTION QS (0.0515(.
