Abstract

Introduction: Dam reservoir Sedimentation is known as one of the main serious problems that mainly affects the efficiency of dam's operation. Sedimentation may also block the conduits and it can destroy turbines, sluices, and valves. So it is necessary to find a way to solve this problem. In this regard, hydrosuction considered as a proper alternative and a potentially efficient method to remove the superficial deposited sediments from reservoirs. Hydrosuction system consists of a large pipeline working with an inlet Suction Tube lying on deposited sediments in the reservoir. In hydrosuction systems, the deposited sediments are withdrawn, as a mixture of sediments and water, from the reservoir and directed to downstream. The major advantage of using hydrosuction method is its economic aspects since the system doesn’ t need extra energy for operation. Environment friendly method, hydrosuction can be used all over the reservoir, where the output and the volume of sediment removal could be under control. Researchers have tried to evaluate and improve the efficiency of this system. In this study, the effects of different shapes and forms of the suction mouth (tube inlet) on the efficiency of hydrosuction system in sediment removal were investigated. To achieve this goal, several experiments were carried out using different shapes of the suction mouth including the plain-type (circular) and wedge-shaped in the middle of the suction mouth...
