CREST KINEMATICS IN WAVE GROUPS

The measured kinematics under the crest of the highest wave in some simple two-dimensional wave groups are presented. The highest wave in each group has the same gross characteristics of height and period but each is embedded in a different wave environment. The measurement technique used, Particle Image Velocimetry, allows accurate velocity measurements to be made up to 95% of the wave height. The measured kinematics show significant differences between wave groups for very high crests, although this is not reflected well in comparison with standard theories (Wheeler stretching and Dean's Stream function).
