Abstract

Dams are the most important water structures and estimating the volume of sediment input to the reservoir and its distribution is important in their operation. Ghezel- ozan River plays an important role in supply of water to the Sefidroud Dam Reservoir as well as the sediment input to it. In this study HEC-RAS mathematical model was used to simulate the hydraulic flow and the sediment in the final 14 kilometers of the Ghezel- ozan River leading to the Sefidroud Reservoir. DEM maps and the Ghezel- ozan FLOW AND SEDIMENT data at Gilvan station and the sediment output statistics from the dam at Roudbar station in the period of 30 years were used as inputs to the model and the river sediment transport capacity was calculated. Also various return periods of river discharge were calculated with SMADA software and were used in the study. Comparing the measured and calculated data indicated that Ackers- White equation had the lowest error estimate compared to the other transport functions. In addition, Hjulstrom and Shields criteria have been utilized to investigate the erosion and sedimentation status of Ghezel- ozan River which showed the erosion status at the sampled river's sections based on the hydraulic condition of the river.
