This paper presented long-term rservoir sedimentation in the Patrind Reservoir of Pakistan and evaluation of the sediment flushing based on the gate operation corresponding to the upstream discharge and sediment inflow using EFDC 3 dimensional hydrodynamic model. Simulated for five years, the invert tevel in the rniddle reach of the reservoir increased up to lOm without flushing, while 5 days flushing after the peak flow in each year contributes to release accumulated sediment through flushing gate. Sediment flushing occurs mainly through the channel foruulaled during flushing operation. From the results of EFDC simulation it is possible to estimate the fiaction of the particle sizE distibution which exc??ed 0.2 mm deposited in fiont of the intake facility since it is known to result in significant tubine darnage. The results of this study will contibute to establish a sound reservoir operation plan considering effcient sediment management. |
