Journal of Coastal Research, Special Issue, No. 75, pp. 482–486. Coconut Creek (Florida), ISSN 0749-0208.Beach profiles and storm related forcing agents were used to assess subaerial beach rotation on an open coast macro-tidal beach. Analysis highlighted a negative phase relationship existed between the beach extremities and variation between negative/positive correlations within the central region identified that medium timescale open coast beach rotation existed. Cross-correlation showed timelag variations in subaerial volume exchange between adjacent sectors lagged behind one another by up to 18 months. While, annually averaged storm climate results highlighted a reduced temporal trend in terms of occurrence, intensity and power. Qualitatively, links were established between storms and erosive/accretive variations in the MHW shoreline indicator that suggest that these events influence beach rotation. Storm wave direction was established to be an important factor and it was concluded that the 3 river estuary complex acted as a surrogate headland restricting sediment by-pass, essentially forming an almost closed cell. These results should be tested at other open coast sites.
