A 3D numerical model is set up to simulate the tidal currents in the Changjiang estuary by ECOMSED model in this paper. This model has been validated with the measured data, the computed results of water level, flow velocity magnitude and direction agree well with the measured data. Based on the sediment grain size of riverbed in the North Branch, Dou guoren´s formula is applied to calculate the sediment incipient velocity in the North Branch, which is compared with the computed bottom velocity fields to analyze the riverbed erosion and sediment deposition in the North Branch. The comparisons suggest that the hydrodynamic condition in the North Branch should be improved for meeting the navigation requirements. The research results can provide the government decision-maker for technical supports.
