Numerical simulation of silt washing by tide based on tidal gate scheduling:Taking the Guan River in the northern Jiangsu Province as an Example
摘要
Abstract
This study focuses on the Guan River in the northern Jiangsu province,where tidal gates have not yet been constructed.Two hypothetical gates are placed at different locations in the estuary.The numerical model of tidal flow in Guan River and the open sea was established by MIKE 21,and the influence of the gate construction location and the gate scheduling methods on the effectiveness of alleviating downstream sediment were investigated.The results indicate that the water level difference during the gate scheduling process,gate construction location,and sediment characteristics have a decisive impact on the dredging effect.Conducting silt washing by tide during high tide periods can achieve better results.However,there is a risk of upstream sedimentation of the gate during the process,it is necessary to combine multiple methods of desilting at the same time.关键词
