Landslide Hazard Zonation in Kerman province with the Models

The purpose of this study is zonation of landslide in Kerman province with Fuzzy and AHP models. In this study in order to obtain hazard zonation map, 7 factors were studied. This factors in GIS software were mapped and then classified and weighted. These maps were overlapped with the landslide distribution map,until the role of landslides distribution to be determined. Finally, the 7 factors including slope, Seismicity, lithology, Drainage density, Morphology, Precipitation, Land use were identified as factors influencing in landslides the basin. The maps the landslide hazard zonation was prepared based on these 7 factors and the methods of AHP and Fuzzy Gamma operator 0.7, 0.8 and 0.9 in GIS. Also the index of Quality sum (Qs) were used for evaluation of the accuracy of zonation maps. The results of the evaluation of the maps showed that the amount the indices Qs for AHP model is equal to 2.31 and for Fuzzy Gamma operator, it would be 0.7, 0.8 and 0.9 respectively 4.05,1.85,3.27. Therefore, it is concluded that the operator the Fuzzy gamma would be 0.7 compared to other methods. So it is better for utilization in the landslide hazard zonation in in Kerman province
