Gabion revetments are known to work as a short-term protection of the eroded beaches. Although rectangular gabions have been often used for the revetment material, round-shaped gabions so-called ‘daruma-kago’ are possible to show better performance in terms of their long-term resistance against the wave force. In this study, stability of the round-gabion revetment as well as beach profile features around the gabions are shown through the laboratory experiments.
