| Three dimensional numerical imitation of tidal current in the Zhanjiang Bay channel based on ECOMSED model |

| Abstract: |
| This study used half implicit three-dimensional ocean turbulence model ECOMSED(Estuarine, Coastal and Ocean Modeling System with Sediments) to build 3D tidal current numerical model of the Zhanjiang Bay upstream channel. The model uses refined orthogonal grid to joint the shoreline boundary in horizontal direction, and uses sigma coordinates to better fit bottom topography in the vertical direction. Through verification, it is shown that the simulation results are in good agreement with the measured data, suggesting that this model can well forecast the dynamic characteristics of Zhanjiang Bay’s tidal, which provides a technical support for further study of the offshore estuary water temperature change, saltwater intrusion and sediment transport. |
