Numerical Model on Hydrodynamic Impact from HZM Bridge

Abstract:

In this paper, a 2D model for the simulation of shallow water flow by convection and diffusion over variable bottom is presented, which is based on the FVM (finite volume method) over triangular unstructured grids. The format of Reo’s approximate Riemann is adopted to solve the flux terms. And the bed slope source term is treated by split in the form of the flux eigenvector. For the diffusion terms, the divergence theorem is employed to obtain the derivatives of a scalar variable on each triangular cell. The numerical model is adopted to simulate the hydrodynamic impact from HZM (Hongkong-Zhuhai-Macao) bridge on Pearl River estuary. The simulated results show that the HZM bridge has little influence on the distribution of hydrodynamic environment in the Pearl River estuary.
