| Zusammenfassung |
| Reducing prediction errors at coastal scales is becoming more important for operational oceanography. As a result, effects such as nonlinear feedback between strong tidal currents and wind-waves can no longer be ignored in the modelling approach. Therefore, it has become necessary to develop methodologies to couple wave- and hydrodynamic models.
At the Helmholtz-Zentrum Geesthacht a nested modelling system is used for estimating reliable now- and short-term forecasts of ocean state variables concerning ocean waves, and hydrodynamics in the German Bight. A coupled system, combining the wave model WAM and the 3-D hydrodynamic model GETM will improve the modelling results in coastal areas like the Wadden Sea and estuaries – areas highly influenced by the tide. First results, obtained with the coupled system, in the German Bight are presented and validated against available observations. |
