Abstract: 

Nowadays in countries involved with landslide problem, there is an increase trend to evaluation and zonation of risk and damage of this phenomena. Identification of regions having potential for landslide occurrence is one of the basic measures in natural resources management. Different landslide hazard zonation models are proposed based on the environmental condition and goals. In this research landslide hazard zonation map using information value model was provided and applicability of this model is investigated in Bagh Dasht watershed. Existing landslides as earth evidence was identified and landslide inventory map was provided. information layers as Geology, slope, aspect, distance from river, distance from road, distance from fault, land use, rain and elevation was provided. For doing this, existing landslides have been identified and an inventory map made. The landslide hazard zonation map is based on the information value in Arc-GIS environment provided. The level of similarity potential hazard classes and figures of this model were compared with the landslide inventory map in the SPSS environments. Results of research showed that there is a significant correlation between the potential hazard classes and figures with the area of landslides. So the information value model is suitable for application in the Bagh Dasht Watershed.
