Abstract

Siltation in the rivers downstream of floodgates is serious in China, making the discharge capacity of rivers decrease obviously and threatening the flood control in upper rivers. Tidal wave deformation is the dynamic characteristic of downstream floodgates, sediment from the sea is the main source of deposition downstream floodgate and unbalanced sediment transportation is the ba-sic model. In the planning and design of floodgate situation choice, coastal deposition and direction of downstream floodgate should be considered. A 2-D numerical model of tide and sediment trans-port is established to simulate the distribution of sediment siltation downstream of the floodgate, and several conclusions are obtained in this paper which can provide some theoretical basis for the prediction and analysis of the siltation characteristics in lower reach caused by floodgates in estu-aries.
