Abstract :

In drainage basin of the northern part of Iran, landslide hazard is increasing because of sensitive formation, incorrect land use, and more rain. One of main strategies for restricting the damage caused by the activity of landslides is assessment and zonation of different region in the term of susceptibility to landslide by prepare landslide zonation hazard map. There are different methods for zoning, Anbalagan method purposed to gain the results. In this method, the required map (slope, aspect, land use, litology, structural litology, ground water, landform and facet map) provided with GIS softwares, Arcmap, then weighted with Anbalagan method. The landslide zonation map is prepared. Finally, for the accuracy evaluation of the Anbalagan method, the landslide distribution map provided for the area. Then compared with landslide zonation map. The results have shown that most of landslides are occurred in HHzone which were predicted by this method.
