Zoning of Landslide Hazard Using Entropy Model Case Study: Zar’ab Basin
Abstract:   (3766 Views)

Actually landslide is the movement of non-condensing and condensing sedimentary layers on the inclined surface that could leave disastrous effects. Zar’ab basin with an area over 3973.94 km2 has 82 landslide spots, appears to be an unstable region. The purpose of this study was to prepare the zoning of landslide risk in the area and determine the factors that influence it. After conducting field and library studies and producing the map of landslide distribution, the effective factors such as geological formations, fault, slope, elevation and aspect were determined. Then we prepared the landslide map by using ARCMAP software and entropy model. The findings of this study show that 55% of the total landslide occurred in the medium-risk range, 37% in the high-risk range, and 8% in the low-risk range and the main reason for this was the effect of roads on the increase of landslide in the area.

Keywords: Entropy, Landslide, Zar’ab, Zoning.
