Flood Control Influence Assessment for a Pearl River Delta Cross-sea Bridge

By constructing a two-dimensional mathematical model and increasing the roughness of the corresponding grid to simulate the water blocking effect of the piers. The effect of a cross-sea bridge project on the surrounding waters is well simulated, the conclusion is given that the construction of the project have very small influence on the water level, velocity, sediment transport rate and dynamic axis of the surrounding waters. The simulation method is reliable and feasible.
