Study on the Influences of Coastline Changes in Hydrodynamic Force and Tidal Prism of Tianjin Offshore Area
Tianjin Research Institute for Water Transport Engineering, M.O.T., Tianjin, China
Numerical simulation of Tianjin coastal waters tidal field by using the Mike21 numerical model. The impact of coastline changes in hydrodynamic force and tidal prism of Tianjin offshore area was predicted. Results show that after the change of coastline, there is no obvious change on the form of flow field at each typi-cal moment for sea areas. But the tidal dynamic condition in most of sea area is weakened to some extent, the most obvious change exists in the flow field of the alongshore reclamation engineering areas. The coastline change is caused by sea filling and, the land accretion directly causes the decrease in the area of Tianjin near-shore waters, so as to decrease the tidal prism.
Key words: Tianjin offshore area / coastline changes / hydrodynamic / tidal prism
