The beach is mapped using 32 Real-Time Kinematic Global Positioning System (RTK-GPS) surveys collected from March 1996 to July 1997. The survey method provides 4 m horizontal spacing and 2–3 cm vertical accuracy. The primary morphology change is the episodic removal and re-establishment of a foreshore dune during the winter swell season. The average sand volume flux between surveys reaches -8 and 4 m2/day during peak erosion and accretion periods. The sand volume of the sub-aerial beach is found to be highly correlated (0.96) with the position of the shoreline. Longshore variations in morphology include beach cusps with typical peak to trough amplitudes of 0.5–1.5 m and longshore wavelengths of 30–70 m. The relationships between the energetic swell forcing and the volume and flux of sand on the sub-aerial beach are examined. The highest correlation (-0.88) is found between the total sand volume and the wave energy flux after the latter is filtered following Wright et al. [Wright, L.D., Short, A.D., Green, M.O., 1985. Short-term changes in the morphodynamic states of beaches and surf zones: an empirical predictive model. Mar. Geol. 62, 339–364]. The filter is effective at capturing slow accretion phases following energetic erosion events.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Steep beach morphology changes due to energetic wave forcing","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:31:06.937317","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"    beaches;     beach erosion;     GPS;     nearshore","OtherDescriptors":null,"Notes":null,"AnaPub":2000,"MonPub":null,"DateUpdate":"2014-03-19","DateCreate":"2003-08-12","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000085933900013","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/S0025-3227(99)00072-9"},"refs":null,"anarec":{"AnaID":38369,"PubliDate":2000,"Pagination":"443-458","XtraPublOfAnaID":null,"ISBN":null,"Volume":"162","Issue":"2-4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43365,"SerRR":"Marine Geology.
