Landslide Hazard Zoning Maps Sufiyan Area By Using AHP Model In GIS

Abstract:
Mass movements are a complicated mechanism that many factors and variables can play roles in their occurrence. In this article the frequency and distribution of large landslides in Sufiyan of the E- Azerbaijan province are studied. The main investigation of this study is to investigate that factors influencing the landslides through Analytical Hierarchy Process (AHP) and then hazard zonation map in the studied region. To do this, six landslide factors, including (1) lithology, (2) slope, (3) the distance of fault, (4) elevation, (5) the distance from the spring and (6) land usage, have been detected as important factors affecting the landslides in this area. Each layer is imported as data into GIS, and their weights are illustrated by using hierarchical analysis. Any how by integrating layers in GIS landslide hazards are mapped in 5 levels as very high-risky, high-risky, medium-risky, less-risky and very less-risky. The results show that most parts of the area are in the very less-risky (43%), and the others covered less-risky (22%), medium-risky (17%), high-risky (9%) and very high-risky (9%) parts of the area. From the mention factors in slopes instabilities, lithology, slope and the distance form fault ordinarily have impact on the slope movements of the studied region.
