Abstract

The development of multiple or harmonic reformed waves following sea waves passing over or breaking on reef structures and in laboratory wave flumes containing artificial reefs or plates has long been noticed. However, this phenomenon appears to have been accepted as a comparatively minor oddity of only secondary concern. Yet on some natural sediment-rich beaches, these same wave harmonics occur, and they nearly completely dominate the behaviour of the shoreface and the visible beach. The Gold Coast of Queensland Australia is one of these beaches, and we report herein of an initial study into the development, impact and incidence of broken wave harmonics on this beach system.
