ADAPTATION OF EXISTING BREAKWATERS TO SEA LEVEL RISE – OVERTOPPING EFFECT

Dang-Trinh Nguyen, Jérôme Brossard

Abstract


This paper describes the wave overtopping measurements of small scale maritime breakwater in sea level rise scenarios which are supposed in French program GICC (Gestion et Impacts du Changement Climatique - Management and Impacts of Climate Change). Many reinforced solutions have been carried out with the purpose to conserve the overtopping rate; among them, the influence of raising freeboard crest is analyzed. The test results are compared with results from literature and with the empirical models presented by Owen (1980), Van der Meer (1998) and Besley (1999). Since then, a guideline is proposed for a better prediction of wave overtopping with various types of high crown-wall.
