Abstract: 

Every year, all over the world, landslides cause considerable damage to life and property. In order to prevent the danger and destruction brought about by landslides, it is important to identify the reasons for the occurrence of this phenomenon. This can only be achieved by conducting a thorough investigation into the geological conditions of the region and a study of the local and global landslides that have occurred in the past across the years. In this research, the reasons for occurrence of land, slides in the region have been studied, in addition to the identification of lithological, geological, morphological and tectonical characteristics of the region around the dam. In abutments, landslides occur due to weak lithologies, discontinuities and a high topographic gradient. Landslides around the reservoir occur due to an increase in pore water pressure and changes in water level of the reservoir, in addition to the reasons mentioned above. Finally, the importance and the role of this phenomenon regarding dams and the region have been studied and explained in this research.
