By comparing Figure 4.56 with the measurements reported in Sørensen et al
(1998, figure 15 p 169) it is seen that the computed eddy structure agrees
quite well with the measured structure with respect to the location of eddy, the
size of the quiescent area in the centre of the eddy and the maximum speed.
As reported in Sørensen et al (1998) the main discrepancy is in the area out-
side the lee of the breakwater. The model results show that the strong jet
along the wall of the breakwater is only slowly disintegrated and bent towards
the shoreline, while in the experiment, the jet is bent very strongly at the tip of
the breakwater.
