A high mound composite seawall, which has a permeable front wall with a dissipation chamber on the superstructure, on a relatively high mound was newly developed as a revetment for reclaimed land or artificial island. Newly developed seawall was constructed in the Mori port of Hokkaido and field observation was conducted to investigate the wave-overtopping characteristics. It is shown that the wave-overtopping rate gives good agreement with empirical prediction methods derived from laboratory test by Kimura et al (1999), but wave run-up height was found to be higher than prediction methods. Furthermore, large-scale model experiments were conducted to clarify the wave-force characteristics of wave splash barrier, which were countermeasures against wave-overtopping.
