The breakwaters protecting Port of Haina in the Dominican Republic have been repeatedly damaged by hurricane storm waves. Attempt to repair the destroyed portions have been largely unsuccessful. A discrete spectrum model developed by Dr. D. T. Resio was used to estimate waves from recorded hurricanes and was followed by extensive mathematical and physical model tests. The preferred solution involves reorientation of the breakwater head, placement of 80 and 26 metric ton concrete cubes on the head and exposed sections, and rehabilitation of the breakwaters by reuse of displaced five-, ten-, and fifteen-ton concrete blocks.
