In addition to reducing the useful storage capacity, sedimentation in reservoirs makes changes to a river basin and reservoir morphology. Depending on the amount of incoming sediment, trap coefficient and the manner of settling, the useful life of the reservoirs varies. With the movement of sediments towards the body of the dam and the obstruction of the discharging gates and turbine valves, the dam operation will practically face problems. Therefore in sedimentation studies, besides the incoming sediment, its movement rate towards the body of the dam, and the sediment deposit procedure must be taken into account.This paper presents a study on Shahid Rajaee reservoir in Iran in which first, by using AutoCAD Civil 3D 2011 software, the geometrical information of the reservoir such as its volume, area and longitudinal profile are obtained from hydrographic maps. Then with observed data and empirical methods, the amounts of sediment inflow as well as its settling pattern in the reservoir are studied and the future of sedimentation procedure in this reservoir is anticipated.<\div>
