Sediment Removal from Deep Reservoir Dams by Suction and Jet Flow [PDF]
One method of sediment removal from dam reservoirs is the use of submerged pumps and suction mixes of sediment and water. This method is usually considered for shallow rivers but we want to adopt this method for large dams.

Based on the similarity law of jet pump, a new cavitation parameter σ is proposed which has the similar meaning to Thoma's cavitation parameter in turbo pumps. The σ values are determined theoretically and presented as the function of specific speed nsj so that we may predict cavitation directly by using it in the designing. Experiments are carried out
