Abstract

This paper concentrates on observed surface instabilities on the crest of waves breaking over a bar. Experiments were conducted in a 3-D wave basin to determine the correlation between the size of the observed instabilities, herein referred to as "fingers", and the incident wave parameters. Digital video of the instabilities was captured for each experimental run. Eighteen tests were performed for varying incident wave heights and periods to obtain a reasonable range of incident wave parameters. The digital video was analyzed to determine the size of the instabilities. No apparent dependence of the widths of the fingers on the incident wave parameters was found. The finger widths appear to decrease with time within one breaking wave and do not appear to vary with distance offshore of the crest.
