STUDY ON CHARACTERISTICS OF TRANSPORT OF SPRAY AND SOUND ENVIRONMENT BY NON-WAVE-OVERTOPPING TYPE SEA WALL

Authors have proposed a non-wave overtopping type seawall (Flaring Shaped Seawall) with deep circular cross section in order to facilitate a safe and excellent use of coastal space for various purposes. The seawall satisfies a non-wave overtopping condition with extremely lower crown height in comparison with conventional upright seawall. In this study, wind field near the seawall, water spray transported behind the seawall and sounds when waves running up were measured in the experiments, and compared with an upright seawall.
