Abstract:Brighton Marina (constructed 1972-1976) is protected by circular caisson breakwaters, Terrett et al (1979). Wave loads were analysed from model tests in the early 1970s with overall stability derived for a 1:1000 year condition, apparently dominated by wave impact loads. Over the last 30 years, repairs have been needed to areas of foundation, primarily to repair, enhance and extend toe protection, but also to repair some degradation to the concrete. The paper will outline approaches being taken to analyse and mitigate threats to these breakwater over the next 120 years. Development of the long-term strategy is led by Hemsley Orrell Partnership (HOP) for Brighton Marina Estates Management, with analysis and modelling by HR Wallingford.
