| Abstract: | The 3-D ECOMSED ocean model was applied to establish a time-dependent boundary model for Jiaozhou Bay (JZB), in which the
operator-splitting technique was used and the ‘dry and wet’ method was introduced. The influence caused by JZB reclamation
on the surface level, residual currents, tidal system and tidal energy of M2 tidal system were predicted and analyzed. The results show that JZB reclamation has slight impact on the M2 tidal system, in which the variation of amplitude and phase is less than 1%.The changes of the currents and residual currents
in Qian Bay and near the reclamation areas are greater, but in other areas the changes are smaller, in which the currents
have a change of around 1%, while the residual currents change ranges from 1.82%–9.61%. After reclamation, the tidal energy
fluxes increase by 2.62%–5.24% inside and outside the JZB mouth, but decrease by 20.21%–87.23% near Qian Bay and the reclamation
area. |
