Abstract :
Natural hazards as an important factor for the environmental planners. These hazards areexacerbated by the Human Performance, However, flooding is not exempt from thisphenomenon. In this article the influence of various factors to determine the risk areas.However one of the factors leading flooding hazard, the development of rural areas in thesurrounding rivers and floodplains.so The zoning maps, flood risk in the management, Thishazard can be very effective And the authorities used in order to assist planning . In thisstudy , methods use statistical data, analysis of spatial data and the use of Satellite images forpreparation curve number in model scs With GIS technique.in the step use CN map andpreparation layer,zoning potential Similar runoff are determined In Based on the results of themodel About 48% of the floor without a runoff, and the runoff is low, 36% moderate and 16%runoff classes are too severe. The severity of flooding is concentrated in the southern half ofthe province.In this part of the study, the mapping of these factors in the GIS By analyzing inthe buffering and danger zones with varying intensities determined Finally, the mostvulnerable villages in the region in terms of the severity of these risks are prioritized.Suchstudies can provide useful guidelines for the identification and assessment of natural hazardsand priorities Settlements also provide risk managers and planners will be responsible in thisregard.
