Abstract : Tests were conducted on 1:68.5-scale models of breakwater sections to obtain data from which economical and stable designs could be developed for repair of the damaged breakwaters at Kahului Harbor. Proposed designs involved protective cover layers od 35- and 50-ton tribar armor units. Design of the breakwater repair was difficult because of the large prototype design wave (34 ft high), the limited space between the concrete monoliths on the crowns of the existing breakwaters and the limits of the navigation channel and harbor basin, and the limited lifting capacity and horizontal reach of available construction equipment at Kahului. Repair designs were developed, for both east and west breakwaters, that would withstand the attack of the selected 34-ft prototype design wave. It was also determined that repairing the damaged portion of the west breakwater head would not cause damage to the undamaged portion of the head and trunk. (Author)
