Abstract:
The aim of this study is an experimental investigation on landslide hazards in Tajan Basin and its increasing due to land use changing, deforesting, road and other construction. The main strategy for restricting the damage caused by the activity of landslides is to avoid these regions. To accomplish this, landslide zonation hazard map of the area is required. There are different methods for zoning of different regions in term of susceptibility to landslide. Because of geological conditions of the study area, Anbalagan method purposed to gain the results. For landslide hazards zonation map the required maps of slope, aspect, land use, lithology, structural lithology, ground water, landform and facet map prepared using GIS software of Arc view and Arc map related to Anbalagan method. For the accuracy evaluation of the used method landslide distribution map provided for the study area which has compared with the landslide zonation map. The results showed that the most of landslides are occurred in VHH zone (28%) and HH zone (55.5%) and the rest of them are occurred in MH zone, which have predicted by the mentioned method. The results of fieldwork performed in summer 2008 with the method of Anbalagan were used to assess slope failure.
