Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
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.
