The relaxation of the construction criterion for leveling of armor stones in mound is expected to reduce theconstruction cost of a breakwater covered with wave dissipating blocks in Open Sea. The stability of armor stonesin the “non-leveling” and “heaping up” construction methods is studied in a hydraulic experiment. The result forthese cases is compared with that for the general leveling. Additionally, the diagram giving the critical depth for anallowable damage rate of approximately 3% in the non-leveling method is proposed.
