Abstract :

Landsliding is one of the many natural processes that shape the surface of the earth, and it is only when threatening mankind that they represent a hazard. Landslides belong to a much broader group of slope processes referred to as mass movement. Landslide hazard zonation helps in identifying strategic points and geographically critical areas prone to landslides. BAGHERAN mountain area in the south of BIRJAND city due to variety in lithological features and environmental conditions such as slope, precipitation rate, earthquake, and etc. is susceptible to land sliding. To evaluate landslide susceptibility in the area, landslide controlling factors were identified through analysis of existing maps, data and field survey.
In the recent years, Geographic Information System (GIS), with its excellent spatial data process ability has attracted great attention in natural disasters assessment. Therefore in this study, a number of factors contributing to the likelihood of landsliding were considered in the Geographic Information System (GIS) environment, including lithology, slope, tectonic activity, land use and groundwater. In this study based on ANBALAGAN landslid model process and Geographic Information System, Landslide hazard zonation processes have been take place. The landslid hazard zonation map in divides the study area into four zones of landslide vulnerability viz., very high, high, moderate and low. Based on results the very high hazard zone covers about 2% of the total study area.
