Abstract

Shirin-Dareh river, located in Khorasan Shomali province plays an important role in providing the regional water supply. Given the importance of the river, the present study is an attempt to assess SHIRIN-DARREH RIVER EROSION and SEDIMENTATION conditions using HEC-RAS MATHEMATICAL MODEL. Therefore, for simulation of river flow, 38 year flood data measured at Ghetlish gauging station located on the SHIRIN-DARREH RIVER, have been used. HEC-RAS model was then run for a 25-year discharge (284.8 m3/s). After calibration of the model, the results obtained were used for the performance of river SEDIMENTATION. To model the river SEDIMENTATION, 19 sediment samples were collected from the river. By simulation, the SEDIMENT TRANSPORT capacity of the river was determined for different sections. A comparison between the obtained and observed values indicated that the Larson equation, with fewer errors, had a more acceptable estimate compared to other existing equations. Accordingly, it is suggested that this model be used at different sections of the river to determine its SEDIMENT TRANSPORT potential and to assess the river's EROSION and SEDIMENTATION conditions.
