Abstract

Water EROSION Prediction Project (WEPP) is a computer model that can estimate EROSION and SEDIMENT of hillslope and watershed, based on individual events and/or in successive years. In this study, water EROSION and SEDIMENT were determined in all sub- catchments and in whole of Bar-Erieh Neyshabur watershed, located in the North East of Iran. The data required for WEPP MODEL are entered in six files, namely soil file, management file, climate file, slope file, channel file and impoundment file. In this study, after determining of same units, the information for developing files related to soil, management, climate (The data related to climate were obtained from climatology station of region), slope (This factor was determined by GEOWEPP SOFTWARE) and channel were collected. In this region there are 21 soil types, 18 management types, 4 channels types. After making the files, WEPP MODEL was run via GEOWEPP SOFTWARE. It is notable that in this software water EROSION and SEDIMENT amount was estimated by three methods of hillslope, watershed and flow path. In these methods SEDIMENTs estimated were 8.52, 4.08 and 14.24ton/ha/year, respectively. According to estimated results, the hillslope and flow path methods with 8.52 and 14.24 ton/ha/year were in good agreement with actual amount (11.2) and are suitable for the EROSION and SEDIMENT estimation of Bar-Erieh watershed.
