The results from the phase-resolving MIKE 21 BW model has been compared
to a phase-averaged model MIKE 21 NSW (default model parameters). The
upper panel in Figure 4.26 shows a map of significant wave heights and wave
directions. The lower panel in Figure 4.26 shows a comparison between the
two models prediction of the significant wave height along the horizontal line
indicated in Figure 4.27. In general the agreement is good. MIKE 21 BW pre-
dicts slightly higher waves along 600-900 m, which is mainly due to the non-
linear shoaling. At the harbour entrance (1100 m) the two models predict
similar significant wave height.
