Abstract

Suspended sediment produced by channel dredging will affect the marine environment. In this paper, a two-dimensional mathematical model of tidal current in Sanmen Bay was established. A continuous moving point source was used to simulate the diffusion of suspended sediment in the dredging process of a channel in the Sanmen Bay. The diffusion rule was analyzed, the calculation results show that the suspended sediments diffuse with the rising and falling tides, and the transport direction of the suspended matter was basically the same as the tidal current.
