Abstract

To study the effect of SECONDARY CURRENTS on sedimentation processes at WATER INTAKE, the strength of SECONDARY CURRENTS were experimentally investigated. A series of experimental tests were performed in fixed and mobile bed conditions with no vane, and parallel and zigzag vane arrangements. The strength of the secondary current was measured for 10, 20, 30 and 40 vane angles installation. From the fixed bed experimental result, it was found that the 20 degree zigzag arrangement produced minimum strength in the secondary current; Thus, it is selected as the efficient angle for vane installation. From the mobile bed experiments, it was found that the sediment entry into the WATER INTAKE was reduced by 72.86 percent for zigzag arrangement and by 63.94 percent for parallel arrangement when compared to no vane installation. Therefore, the zigzag arrangement was found more efficient when compared with parallel arrangement due to 9 percent sediment entry reduction into the WATER INTAKE.
