Abstract : Tests were conducted on a 1:50-scale model of the north jetty at Humboldt Bay, Calif., to determine information from which economical and stable repair sections can be designed to stop deterioration caused by wave action of the seaward ends of the north and south jetties at Humboldt Bay. Tests of the south jetty head were not conducted since results of the study of the north jetty head will be applicable to future repairs on the south jetty. The study included the investigation of (a) the waves that can attack the proposed structure, (b) the effects on stability of linking the armor units, and (c) the optimum shape of armor unit and repair section that would be stable for the selected design-wave conditions.
