Abstract: Multipurpose artificial barrier reef is proposed for the enhancement of fisheries as part of the purpose of entire system of structures in Japan. As part of our planning efforts we are required to investigate the living environment of marine life as a factor of environmental decision-making between the restrictive condition of the various plans. We have conducted investigation of actual conditions of natural rock in the vicinity of planning area, and investigation of diving, thereby accurately determining the relationship between marine life and habitat water depths. We have also been conducting hydraulic model tests in current structural configuration, focusing on structural stability and hydraulic characteristics. In conclusion, we propose a tentative plan for the planning and design methods of multipurpose artificial barrier reefs.
