  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.

  The geomorphic units of the fluvial system components are in a way that in many cases geomorphic processes are causing environmental hazards such as floods. In this research Torghabeh city and its basin have been studied for  the hazard of a river geomorphic processes. Torghabeh town as a regional and international tourism attraction is 20 kilometers far from the metropolitan city of Mashhad. The output of the upstream catchment basin with regard to the geomorphic variables highly affect the flooding possibility  of the city. In order to conduct the present research, a laboratory analytical method to investigate the behavior of the studied basin, the fluvial geomorphic variables and factors in the flood hazard area, including lithology, elevation, slope, land use, precipitation, vegetation, drainage density, distance from the stream, form factor, slope and soil were selected and included in the research. The layers were required to prepare, prioritize and establish the relationships between these variables and the vulnerability of the Analytic Hierarchy Process (AHP).  The Expert Choice software was used to help wit the analysis . Critical flood hazard zones are mainly rural area with densities, recreational areas and resorts, tourist and Network Access Account in Mashhad. It is important to notice that, the  man-made factors such as residential and utility violated the privacy of rivers and streams, lack of engineering structures such as bridges over rivers of improper aggravating factor are the most significant variables  in the flood hazard area. Leveling and terracing of slopes for construction not only disrupts the balance , but also it has increased the weight of the load of  flood intensity. The damages caused by the flood of mass movements within the city limits has been exacerbated in Torghabeh.           Manuscript profile
