摘要：

A 2D current model about Changjiang River Estuary was set up with Delft3D-FLOW in this research, which was well calibrated and verified with the observed tidal levels and velocities, the computed results of water level and flow velocity magnitude agree well with the measured data. The model has been applied to calculate the flow velocities and the split ebb flow ratio of the North Branch with the diversion angle of 30o and 60o respectively. The computed results show that the smaller the diversion angle of North Branch is, the larger the flow velocities and the split ebb flow ratio will be. Therefore, the diversion angle plays a positive role to the dynamics improvement in the North Branch.
