Abstract

Nowadays, SEDIMENT control at intakes is an important problem in the hydraulic structures. SEDIMENT transport causes many problems in channels, irrigation networks, and turbines in powerhouse and in river engineering. SEDIMENTation reduces the useful life of a reservoir. Since obstruction of river flow causes SEDIMENT deposition upstream of WEIRs, usually sluices must be constructed. This is especially true when WEIRs are of the overflow type. One of the main points regarding the removal of deposited SEDIMENT upstream of WEIRs and mainly in the vicinity of the inlet structures is the extent of the eroded area. Amongst different parameters affecting flow characteristics and therefore capacity of the flow to erode the bed upstream of the SLUICEWAY are width and the optimum opening of the SLUICEWAY. The sluicing processes during transition period are not well defined. Therefore experimental results on some effective parameters on the variation of SEDIMENT removal are reported in this paper. Experiments are done in a flume with 12 m length, 75 cm width and 80 cm depth. A diversion WEIR is built 1 rm. upstream of the channel end. In these paper experimental results on the effect of SLUICEWAY width, flow discharge, gate opening, upstream Froude number, and ratio of gate opening to SLUICEWAY width on the efficiency of SEDIMENT removal is reported. Four different widths, 8 different flow discharges in combination with eight different sluice gate openings are considered which results in 256 experimental data set. It is shown that increasing the SLUICEWAY width generally results in increase of the SEDIMENT removal. However, this trend is more noticeable in the lower range of the SLUICEWAY width and further increase in the higher range of the width will not make much difference in the SEDIMENT removal. Therefore, it is possible to find a range of optimum values for the SLUICEWAY width. Also it is shown that for higher values of flow discharge, the extent of the eroded bed could reach to such an extent upstream of the intake structure, which decreases the efficiency of the SLUICEWAY.
