WAVE-TRANSMISSION OF VERY LARGE AND FIXED BOTTOM-DETACHED BREAKWATERS IN A NUMERICAL WAVE FLUME

Climate change and energy crisis are fueling wide concern. Coastal areas are prone to the effects of sea level rise and change of wave conditions as the results of extreme conditions and the increasing number of coastal risks. These phenomena drive coastal erosion, and the lack of alternative dwelling space leads to the higher density urban structures in coastal communities. Expanding human’s activity space toward exposed offshore marine areas is a big challenge in term of scientific and technological issues. The use of floating structures, such as the Very Large Floating Structure (VLFS) (Bouchet et al., 2004), is a potential solution to expand activity space and cope with the sea level rise with a resilient approach. In the past, most of research activities have focused on the relatively small floating structures located in intermediate or shallow waters in naturally protected marine areas.
