Abstract

The baymouth breakwater is to protect the port area from tsunami. It narrows the bay mouth and prevents tsunami from flowing in the port area. A submerged breakwater is built at the central opening section of the baymouth breakwater (Tsunami breakwater) to close the bay mouth as much as possible. Because of narrowness, it is expected strong current is generated at the opening section of the breakwater when tsunami occurs. The purpose of this study is to examine the stability of the opening of the breakwater on the basis of the result of numerical wave tank. Thus, conducting the experiments of the stability of the opening of the breakwater in large flume confirms the validity of results of calculations.
