Experimental study on the effect of circular jet on sediment flushing in reservoirs

An important concerns pertaining in water resource management is the deposition of sediment in dam reservoir. The importance of implementing reservoir sediment management techniques to preserve reservoir storage space is evident. In this research, the effect of submerged single circular jet was experimentally investigated on flushing efficiency. The results showed that the best position of jet respect to the outlet positon in a given jet velocity and the outlet discharge ratio between 46 and 83 is twice the outlet diameter. The best position of jet for outlet discharge ratio between 120 and 157 is 2.5Doutlet.
