Abstract: 

Sediment control at lateral intakes is known as a complicated issue for river engineers. In this study, numerical simulation of the impact of submerged vanes and spur dike on sediment control at lateral intake has been performed. For guiding flow into the diversion channel and increasing the vane performance, a single spur dike in opposite side of the intake has been utilized and the effects of spur dike length, the location of intake, and the angle of attack on reducing the movement of bed-load sediment into the diversion channel have been investigated. Obtained numerical results consisting with the experimental data confirmed this face that the effective performance of the vanes can increase using a proper spur result in eliminating the bed-loadsediment ingestion rate into diversion channel. Then, numerical results were compared with experimental results and there was good agreement between them.
