Abstract

Breaking waves generated by focusing of transient wave packets have been analyzed. By a comparison of video data and gauge measurements the threshold frequency for the use of the PTM as a breaking criterion is derived. The present result is slightly higher than the original value of Zimmermann & Seymour (2002) for spilling breakers, but confirms the results of Irschik & Oumeraci (2006). Additionally the use of the zero down-cross period Tz instead of the peak period TP is investigated. Both definitions lead for the present conditions with plunging breakers to almost identical results.
