The zonation of flood susceptibility in drainage basins using GIS Case study: Gavehrood basin

One of the most important problems in drainage basins management is the calculation of flood intensity in sub basins. Certainly recognition of effective factors in flood intensity rate can be efficient to estimate of this factor in basin without hydrometric station. The object of this paper is the recognition of effective factors in flood intensity of Gavehrood basins in the west of Iran. The result of this research used to flood intensity zoning to sub basins and each of them classified in runoff potential categories. To preparing of needed data for this research has been used remote sensing technique to provide vegetation index map. After the providing needed information and fed to computer, using different method of GIS extract the result.
