Abstract

A 3D numerical model is set up to simulate the tidal current and sediment transport in the Changjiang River estuary with ECOMSED model, which has been validated with the measured data, the computed results of water level, flow velocity magnitude and direction, and suspended sediment concentration agree well with the measured data. This paper analyzes the influence of Hengsha Passage on sediment deposition in the upper reach of the Deepwater Navigation Channel in the Changjiang River Estuary by use of this model, in order to explore the reason for the sediment deposition in the upper reach of the Deepwater Navigation Channel.
