Title

Landslide susceptibility zonation in Shahid Abbaspour Dam district

Pages

  65-80

Abstract

 Landslides are one of the most important slope movements. One of the Landslide-prone areas is the area around the dams and their lake, which may cause damage to the dams. The purpose of this study was to identify areas prone to Landslides in the area of Shahid Abbaspour Dam, Northern Khuzestan, Iran. This research was conducted using two methods of Hayeri-Samiei and Analytical Hierarchical Process. Based on this, seven factors including lithological, slope angle, fault length, road and river length, rainfall factor, rainfall intensity and earthquake were prepared. In the Hayeri-Samiei model, these seven factors are investigated and the obtained weight of each of them is placed in the general equation and in the GIS environment is converted into a Zonation map and potential areas in the range are identified. In the Analytical Hierarchical Process method, based on pairwise comparisons between the seven factors mentioned, considering the opinion of experts, the weight of each factor is obtained and in Expert Choice software, pairwise comparison is performed and the final weight is obtained. After studies in two methods, the most Landslide-sensitive areas are in Quaternary young alluvium and lithological factor is the most important factor in the study area. In general, high-risk areas are in the southwestern part of the dam and a small part in the north. In AHP model, like Hayeri-Samiei model, the lithological factor has the greatest effect on Landslides in the region. Gachsaran Formation also has very low resistance to Landslides after Quaternary alluviums. In terms of slope angle, areas located at slope angles of 36-45 are prone to Landslide.
