Abstract
Dams are one of the most common structures to make a reservoir for water accumulation. Sediment deposition in reservoirs not only reduces the storage capacity of a reservoir but also decreases its useful life. Also, in many cases sedimentation creates problems for bottom outlets. In this study simulation of sediment deposition in Jiroft Reservoir is investigated with the aids of GSTARS3 model. At first the measured data of Jiroft Reservoir are used to calibrate the mathematical model. The Manning coefficient and the sediment transport equations are used for this proposed. After calibration, existing data are used for verification of the model. Finally, the time variation of reservoir volume is calculated. The results showed that the mean annual volume reduction of the reservoir is approximately equal to 1.27 percent of initial volume. Also, the trap efficiency of the reservoir is computed and it was equal to 87 percent.
