Test study on the impact of the alignment on the tidal factors in Huangmao estuary

On the basis of physical modeling, the impact of different alignments on tidal factors such as tidal stage, tidal current velocity and tidal volume under the combined action of different runoffs and tides is studied, and the problem which causes the change of these tidal factors is analyzed. The impact of the variational trend on the water level of flood control and the water depth of navigation channels is explained.
