THE SILTATION MECHANISM AND REGULATION APPROACHES UNDER THE DOWNSTREAM COURSE OF TIDAL SLUICES

摘要

Serious sediment deposition often occurs after the construction of tidal sluices in small or middle-sized tidal muddy estuaries. In this paper, the sediment movement and mechanism of sediment deposition induced by tidal sluices are analyzed, it shows that tidal wave deformation and net sediment transportation from sea to river course are the main reasons for siltation. Different problems of siltation near tidal sluices for different types of estuaries are summed up, at the same time, corresponding regulation methods are given to solve these problems.
