Abstract

 The JAJROD river basin is situated in the North-eastern of Tehran (the capital of Iran). It is more susceptible to landslide, mud flow, and other forms of mass movement. Landslide is one of the most natural hazard that causes damage to city and rural inhabit, cultural lands, roads, forest and so on. Therefore it is obvious that the LANDSLIDE SUSCEPTIBILITY MAPPING is very important for environmental management in this region. In this research 150 landslides by field study and air photographs were recognized and mapped. These landslides also pointed on 1:50000 topography map of the JAJROD river basin. Determining the effective factors on landslide in the JAJROD basin is the second stage of this research. Litho logy, Slope, Slope direction, Land use, Distance to fault, Digital elevation model (DEM) and precipitation were the seven factors that studied and analyzed by logistic regression model in GIS environment. The result of this research represent that the ANALYTICAL HIERARCHY PROCESS model is the suitable method for predicting the landslide hazard risk in this area. At the final the landslide hazard risk map of the JAJROD basin is classified in five class containing, very low, low, medium, high and very high hazard risk. In this classification about (%62) identified as high hazard risk in the JAJROD river basin.
