Hydrodynamic Mathematical Modeling of the Yangshan Deep-Water Harbor Waters, China

Taking Yangshan sea-area of the Qiqu archipelago as an example, a 2D numerical model of tidal currents is established to study the change of the current field and the influence of branch blocking in different stages of northern port construction, including tide process, velocity and tidal prism, in the main channel waters and the branches. Verifications with the observed data indicate that the simulated results can reflect the current fields in the region. Based on the numerical model it is rechecked and researched the influence of branch blocking in different stages of northern port construction on the changing processes of hydrodynamic, including tide process, velocity and tidal prism, in the main channel waters and the branches. The paper is to provide the scientific basis for the construction of Yangshan Port’s subsequent engineering.
