Thair Mahmood Al-Taiee ABSTRACT The feasibility of flushing sediment from the Mosul Reservoir located in northern Iraq was examined. Many current criteria and indices for checking the efficiency of flushing sediment from reservoirs have been reviewed by analyzing large amounts of data from many flushed reservoirs, and these have been tested and applied to the Mosul Reservoir. These criteria and indices depend mainly on the hydrological, hydraulic, and topographic properties of the reservoirs, in addition to their operation plan. The main criteria for successful flushing of sediment in this reservoir are the sediment balance ratio (SBR), the long term capacity Ratio (LTCR), the draw-down ratio (DDR), the shape of reservoir (L/W), and hydraulic conditions such as the percentages Qf/Qin and Vf/Vin. There is no verification for other criteria such as flushing width ratio (FWR), capacity inflow ratio (C/I) and sediment potential (SP) .The results agree with requirements for successful flushing and indicate that flushing sediment in the Mosul Reservoir is feasible to a certain degree, and can be applied in the future to conserve water storage capacity.
