Based on the basic technology established in the knowledge of flap- gate-type breakwater, the newly developing flap-gate-type rising seawall was applied to improve the coast protection facility of Muya port, Tokushima, Japan. It has been put to practical use to overcome various problems due to the on-land installation. It is a new type of seawall, using the buoyancy during inundation at the time of tsunami, tidal wave/storm surge, in which the gate leaf turns upright and falls without power/manual operation. In this paper, the basic idea of design and maintenance based on the applicability study of flap-gate-type rising seawall to the Port of Muya is presented.
