| Abstract: | Sediment deposition in area of tide gate is a universal problem in mouth region of alluvial rivers. Using tidal flow with higher flow velocity to wash out the bed mud can reduce the sediment deposition in area of tide gate. Based on the laboratory experiment on the tide gate of The Suzhou River, this paper discusses the influences of different affecting parameters on clean-out of deposited sediment around tidal gate and analyses the clean-out effect under different tidal conditions and with different opening forms of the tide gate. |
