Study Of Mathematical Model And Suggestions On Seashores Sediment Transportof The GrapeBay

The demand for exploiting coastal sea area is increasing as the economy develops rapidly in recent ten years. As much coastal land reclamation from the sea instilled new vitality into the territorial economic growth, they also resulted in a host of environmental issues such as changing the original dynamic environment or some other influence on functions of ocean which are worth serious researching and deep discussing. This paper used methods of data analysis and numerical simulation to study the reclamation’s influence on hydrodynamic environment of the Grape bay by analyzing the changing of hydrodynamics and sediment because of reclamation in Weihai fishing center port on the basis of model verification. There are some main conclusions:(1) the project reduces wave input from open sea effectively, which makes wave height decrease in the Grape Bay. (2) Sea Reclamation Project varies the movement of tidal current field, weakens the tidal current and hydrodynamic conditions. (3) After the project, the large-scale sediment deposition in western Grape Bay, is not from open sea, but from the other part of the bay, because hydrodynamic environment changes. This research can provide some suggestions to regulation project in the Grape bay and also can benefit the similar demonstrations of reclamation.
