Abstract

 Significant proportion of national and infrastructure investment devotes to construction activities in nature. These investment must be selected with sufficient confidence to ensure survival and duration of vital interest. In this study after collecting information including slope angle, lithology, fault’s length, River’s length, Road’s length Rainfall, earthquake and vegetation in packed cell map is processed in GEOGRAPHICAL INFORMATION SYSTEM (GIS). finally landslide hazard zonation in Doroud-Andimeshk railway is presented. ZONATION MAP of the area is prepared using Moora-Varson method and is validated using AHP METHOD. Slope angle is obtained from digital elevation map of the area.1.250000 topography map is used to obtain digital elevation map. Lithology map is prepared using 1.100000 geological map. Fault’s length, Road’s length, river’s length and vegetation are obtained from Landsat satellite map. Rainfal and earthquake data are obtained from Meteorology center and Geophysical Institute of Tehran. At the end, the area with high risk of rockfall was introduced.
