The Assessment of Rock Fall Hazard in Roudbar-Rostam Abad Free Way

In Geomorphological features of landform equilibrium in the reduction of environmental hazards It plays an effective role. This paper is attempt to clarify the status of the geomorphologic، a logical relationship between the construction of freeways rudbar to rostam abad and unstable scree slopes to a special process to determine the reaction zone is established geomorphological And the objective of this research is study and classification of risk across the rock fall on the freeway Rudbar - Rostam Abad. The method of network analysis in order to analyze the occurrence of rock fall. in the first phase to measure and characterize the clusters and the elements. And 8 of the main elements involved in the thematic similarity of two clusters of environmental features and natural hazards were in place. According to the analysis of the network of rock fall can be said The reasons range from the management zone in terms of road has high- risk areas. This the area is where adjacent to the stream and consists of multiple fault Volcanic masses rock and Loose that have been developed.
