Core-Loc Breakwater Armour Research. Breakwater Survey at Port St. Francis

D. Phelp / S. Heather-Clark

An agreement was signed between the Council for Scientific and Industrial Research (CSIR) and the U.S. Government through its European Research Office of the U.S. Army, for the CSIR to undertake monitoring surveys of the first core-loc breakwater constructed in Port St. Francis, South Africa. Following the base-line survey of the Port St. Francis breakwater, undertaken in October 1997, a follow-up survey was carried out on 26 May 1998. Both surveys consisted of an aerial photographic series taken from a helicopter using DGPS for positioning, a visual inspection, and a diving inspection, and a 'crane and ball' profiling survey. Survey results and analysis of the baseline and follow- up surveys are summarized in this report.
