| Abstract |
Hydrodynamic boundary conditions are needed for the design of new sea defence structures in the harbour of Oostende along all quays to defend the city centre and hinterland from flooding during a super storm. The wave climate in the harbour was decoupled to wave penetration and locally generated wind waves to allow separate modelling of both phenomena. The wave penetration was modelled with a physical wave model, a mild slope equations model MILDwave and a Boussinesq equations model Mike 21 BW. The locally wind generated waves were modelled with the spectral model SWAN. By using a thin sponge layer along the boundaries in the numerical wave penetration models to model partial reflection inside the harbour, very good correspondence is found between the numerical wave penetration models and the physical model. Finally, the wave penetration energy and locally generated wave energy were superposed to obtain the complete wave climate along all structures inside the harbour during severe storm conditions. |
