Since recently artificial reef have been installed offshore on the seabed having rough wave, the stability of them becomes of crucial importance. However they consists of not only tubular members but also plates and box shape members, the drag and inertia wave force coefficients for stability evaluation are uncertain so that we determined through model testing. Furthermore, this kind of. the artificial reefs are required the function of fish-gathering and propagation by attaching the plates causing upwelling current and pilling up stones on their top. The paper also presets that observations and measurements of the current adjacent to the reef and possible wash out of the stones secured by fence in order to confirm the validity of such devices.
