Corporate name Rijkswaterstaat Project SBW Date 2008-07-01 Abstract Results of hindcast studies with the SWAN wave model in the Amelander Zeegat, the Oosterschelde estuary and the Slotermeer were analyzed to detect the cause of under-prediction of low-frequency wave energy in the coastal zone, the causes of prediction errors in the presence of currents and the underprediction of wave heights In depth-limited conditions. The results of this study show that the under-prediction of low-frequency energy is most likelycaused by propagation effects, although the whitecapping formulation and bottom friction may also play a role. Wave heights are overpredicted in opposing current and th is is made worse by application of the adapted whitecapping formulation of WL (2007). The under-prediction of the wave heights in depth-limited situations is clearly worse for steep waves. It was also found that shallow water source terms affect the total source term balance. The under-prediction was the least by applying the surf breaking term with the breaking parameter gamma=O.8.
