A Flap-gate breakwater is a new type coastal structure which lies down on the seabed usually and rises up as a continuous seawall with its buoyancy. Through previous studies and designs, availability of these structures was confirmed as tsunami/surge and wave protection barriers. Present study verifies fundamental capability of behaviors, characteristics of wave responses and effectiveness of maintenance of both structures by a field experiment. As a result, it was proved that influences of aged deteriorations did not occur and that these systems of operations and supports and processes of maintenance were appropriate.
