Sediment deposition at the entrance of river intake structures is an important problem. In case of power-plants that use rivercooling water, sediment deposition reduces the withdrawn capacity, causes damages to the pumping system and causes partial or full blockage of the intake. Sediment blockage may cause stopping of the plant. Submerged vanes are simple structures that can be used to control the sediment and redistribute the flow and the sediment in open channels. An experimental study to minimize the sediment that enters the intake channel using a single row of submerged vanes is investigated. Sixty experimental runs were carried out considering various heights, angles, and positions of the submerged vanes with different flow conditions. The case of flat floor without vanes is included to estimate the influence of using the submerged vanes on sediment control
