Three-dimensional hydrodynamic numerical simulation is carried out to investigate the effects of the coastal land reclamation on the marine hydrodynamics, environment and ecosystem. The changes of tide, tidal currents and residual currents, including tide-induced, wind driven and density driven components due to the construction of the sea dike system are simulated numerically The governing equations transformed into o-coordinates are solved by an implicit finite difference method. The numerical model is calibrated using the tide charts of 4 major tidal constituents, M$_2$, S$_2$, $K_1$ and $O_1$. The numerical solutions show that there are significant changes of residual currents, especially induced by both tidal and wind-driven currents.
