Abstract

Increase in population and ever creasing expansion of urban areas and industrialization of communities in one way, and decrease in natural domains from the other, decrease the vegetation level and gives to soil EROSION and index of surface stream. We have selected siahrood watershed basin in rasht with an area of 204.33 square kilometers, in order to examine different systems of EROSION and estimate EROSION intensity and sediment level by E.P.M method. We have studied named basin from the viewpoint of physiographic, climatology, hydrology, geology, Geomorphology, pedology and vegetation and have used the results to investigate and estimate EROSION and sediment level, and thus classified the basin into one main region and five sub region. in this study, soil characteristics, average slope, soil sensitiveness index to EROSION, land usage index, EROSION index, EROSION intensity index and the class of EROSION intensity have been determined within the Geomorphologic fancies.We have computed the net EROSION, sedimentation index, the discharge of net sediment and the discharge of total sediment in the in siahrood watershed basin.After studying the stylistics of measured discharge of sediment in sedimentometry station in behdan 18 year period, the total amount of annual sediment of siahrood was measured 25161.19 tons. When we compared the amounts of measured sediment and estimated one, by two methods, one conventional and the other developed form of E.P.M, concluded that the estimated amounts with measured amounts of sediment has a 96 percent proximity to the real amounts.
