Full TextAbstract
One of the most effective techniques for removing the deposited sediments from reservoirs is pressure flushing which has less local effects. It is often used as a clearing process to remove sediments around the entrance of intakes. In this study, the effect of bottom outlets cross section on the dimensions of flushing cone was investigated experimentally. The experiment was carried out with different bottom outlet diameters, different discharges and different water depths above the bottom outlets. The results indicate that the volume and dimension of flushing cone are strongly affected by the bottom outlet diameter. Finally, by using regression analysis, a dimensionless equation was presented for calculating the volume of sediment released from a dam during the pressure flushing.
