Verification of water levels during storm events in the Wadden Sea

The analyses include water level measurements at several stations throughout the Wadden Sea, both inside the tidal basins and at open sea. The regional Dutch Continental Shelf Model (DCSM) has been forced with tidal conditions as well as time and space varying wind and pressure fields (based on HIRLAM wind data). The DCSM (1998) model provides boundary conditions for the Wadden Sea Model. To study the wave effects the hydrodynamic model has been ‘online’ coupled with a wave model for this area, computing the wave fields at a frequent interval throughout the storm periods. The Wadden Sea Model has been forced with tidal, wind, pressure and wave conditions. The developed models have been used to investigate the effects of waves during the storm periods on the water levels in the different basins. The computed water levels at the Amelander Zeegat (inlet) will be submitted to other SBW-projects providing water level time series at several wave buoy locations and also water level and current fields for the Amelander Zeegat.
