River management, including strategies that effectively have an effect on the behavior. Geomorphological management, is the study of shapes, nature, and origin, processes of emergence, development and use of human and material composition of the Earth.  The assessment of river character and behavior in Stage 1 is based on analysis of the assemblage of geomorphic units (channel and floodplain landforms) along any reach. Arangeh River basin were identified in 1and 3 styles, including: Headwater, Gorge style in confined valley setting, planform controlled, floodplain bed, low sinuosity cobble, low sinuosity gravel, bedrock controlled sand, meandering gravel, unconfined low sinuosity cobble with Side stabilized, partly-confined low sinuosity cobble with Side stabilized, partly confined Asymmetric valley with cobble, , partly confined symmetric valley with cobble  ,Artificial bed.Geomorphic conditions of each of the styles were evaluated in the two stage of river style framework. at this stage of adjustment of Each style is determined to the confusion of peak flow by using criteria such as channel characteristics (size, shape, morphology Bank and plants channels), channel plan form (sinuosity, lateral stability, geomorphic units into the channel and River flood plain and plants) and features bed . Two Style had good geomorphic conditions (floodplain bed bedrock controlled sand, unconfined low sinuosity cobble with Side stabilized) show the potential of a good adjustment, and the reach has a good of potential adjustments are more sensitive to changes . In the fourth stage of rehabilitation is carried out in reach scales, basins and river basin based on forecasts of possible changes in the future and potential of Geomorphic River Recovery. Each style is proposed management priorities in accordance with the geomorphic and recycling potential.
