Perforated and OWC Caissons
Wave reflection at harbor structures negatively affects the navigability of entrance canals and harbor tranquility, particularly for the case of vertical-wall structures. Reducing the wave reflection at vertical wall structures is thus an important aim. To date, several approaches have been presented in the literature, e.g. slotted vertical perforated-walls or caissons with internal rubble mound. The so-called Oscillating Water Column (OWC) concept is commonly investigated as wave energy converter, thus focusing on energy harvesting. This work investigates the effectiveness of using OWC, embodied in quay walls or breakwaters, as an alternative way to reduce wave reflection.
