NUMERICAL EXPERIMENTS ON OVERHANGING PARAPETS UNDER NON-BREAKING WAVE CONDITIONS

Sea-wall and storm-wall structures aim to protect coastal areas harbours from wave attacks. They are often located in the neighbours of city centres, that turn impose rather severe visual limits affecting maximum height structure. To combine architectonical restrictions overtopping safety limits, imposed by different national standards, alternative solutions such as recurved parapet applied. Even for non-breaking conditions, these subjected large impulsive pressure has been recently described named Confined-Crest impact, (C-CI, Castellino et al., 2018). The C-CI cause recent failures Civitavecchia harbour (Italy, 2021 Dermentzoglou 2020). Accordingly, this phenomenon raised attention researchers professionals who require an additional tool design curvilinear considering reduction performance, structure complexity C-CI.
