It's needed to set the current speed for the open boundary condition in stead of set the water level in order to balance of water volume flowing in and out the calculated domain. First, we verify the consistent of the tide and tidal current in the calculated domain in the case of open boundary condition with tidal level and tidal current. Then we consider the composition of the residual current and tidal current. It's necessary to verify numerically that whether we can give out the open boundary condition with the composition of residual current and tidal current simultaneously. Applied the ECOM, the numerical experiment with the tidal current open boundary codition shows that results are consistent with the tidal level open boundary condition by designing an idealized bay. It is successful to simulate the distribution of residual current in the case of considering the residual current and tidal current at the open boundary simultaneously. The conclusion in this paper can be referenced for the numerical calculation of current in the case of composition of residual current and tidal current.

The saltwater intusion produces salinity front, there exists a land-ward density induced current under the salinity front, and the current speed at the upper layer obviously enhances due to mass continuty through the transverse section. There is a northward component of current at upper layer and a southward component of current at lower layer, this indicates that there exists transverse circulation. The salinity front induced by saltwater intrusion inclines northwestward horizontally that means the saltwater intrusion at the north coast of the estuary is stronger than at the south coast, and inclines toward upstream vertically that means the salwater intrusion at the lower layer is stronger than at upper layer. The higher salt water locates at the lower layer and near the north coast. The dynamic factors of saltwater intrusion are the tidal flood current, the land-ward density current and mixing. The Coriolis force makes the flood current deflect to the north coast, and the land-ward density current exists at the lower layer, those dynamic mechanism result in asymmetry distribution of salinity. The baroclinic pressure gradient force induced by the salinity distribution in transverse section directs the south coast and increases with the water depth, this results in the current at botton layer flows to the south coast. In order to keeping mass conservation, the divergence at bottom layer and north coast produces upwelling and rise of water level. This transverse distribution of water level makes the surface current flows northward, the above dynamic process induces a transverse circulation. The current divergence induced by the spreading width of funnel -shape estuary inner the mouth makes the current weaken and produces upwelling, the distance of land-ward flow of density current at bottom layer reduces,the salinity near the mouth increase, but the saltwater intrusion weakens; There exists obvious higher saltwater at the botton layer and south coast of the funnel-shape estuary; The vertical mixing enhances, and salinity tends to uniform vertically.

The hydraulic jump can be distinguished using the Froude number. When the fliid tidal current velocity exceeds the propagation velocity of tidal wave, the water particles transfer the kinetic energy to the potential energy, therefore the water level abruptly jump and forms bore. Further analysis suggests that narrowed river channel increase flood current velocity and silted riverbed slows down tidal wave propagation velocity. The river channel of the North Branch of Changjiang Estuary has been narrowed and its bed has been silted for recent years because of natural processes and artificial actions, which are the main causes of increased bore frequency and strength. With the bore head advance, a great amount of saltwater and sediments flow upstream. It has profound effects on the river channel evolution and environment of the estuary.
