Landslide hazard zonation in Nojian watershed with the models overlay Fuzzy and AHP

Abstract:   (9071 Views)

The purpose of this study is, the landslide hazard zonation in Nojian watershed with the models overlay Fuzzy, AHP and GIS the technique. In this study in order to obtain hazard zonation map, were studied 9 factors. This factors in GIS software were prepared to map, and then was classification and weight. These maps were overlapped with the landslides distribution map, until be determined role the classes in landslides distribution. Finally, the 7 factor, lithology, slope, aspect, distance from the fault, land use, precipitation and elevation were identified as factors influencing in landslides the watershed. 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. The indexe Quality sum (Qs) also were used for evaluate the accuracy of zonation maps. The results the evaluation the maps showed that the amount the indexe Qs for AHP model equal is by 0.7, and for Fuzzy Gamma operator 0.7, 0.8 and 0.9 is respectively equal is by 0.75, 0.71 and 0.63. Therefore, conclude that the operator the Fuzzy gamma 0.7 compared to other methods is has better utility in the landslide hazard zonation the Nojian watershed, and is reasonable that, be done take any environmental planning with respect to it.

Keywords: Landslide zonation, Nojian watershed, Fuzzy Overlay model, AHP model, Qs method, GIS.
