Abstract

The SWAN wave model for shallow water is used in three generation modes to show the differences in results between these modes and with observations in two real, rather field situations. These are situations of waves approaching two different sites in the Netherlands and Germany: one closed part of an estuary and one region between and beyond barrier islands with channels and tidal flats. The differences between the modes are significant (more than 25 % locally) in terms of significant wave height and mean wave period. These differences are ascribed, at least partially to the indirect effects of triad wave-wave interactions which shorten the wave period. The observations are located at positions where the differences between the modes are hardly significant.
