An undistorted-scale hydraulic model study was conducted to provide input for design optimization of a rubble-mound jetty system proposed for Oregon Inlet, North Carolina. Two-dimensional trunk tests consisted of a developing stable stone and dolos sections base designs for a depth-limited breaking wave of 15 sec, 13.6 ft at a design swl of 5.5 ft b subjecting the stable base designs obtained at the 5.5 ft swl to storm-surge hydrographs with peak levels of 6.5, 7.5, 8.5, 9.5, 10,5. and 11.5 ft NGVD and obtaining damage as a function of swl c redesigning the armoring schemes for stable sections of 7.5 ft swl with a depth-limited breaking wave of 15 sec, 15.5 ft and subjecting these plans to storm-surge hydrographs of 8.5, 9.5, 10.5, and 11.5 ft NGVD and again determining damage as a function of swl and d redesigning both the stone and dolos sections for stability at an swl of 9.5 ft with a depth-limited breaking wave of 15 sec, 17.2 ft. Three-dimensional tests were conducted to determine stable stone and dolos head sections for 15-sec, 17.6 ft waves at angles of wave attack equal to 0, 22.5, 45, 67.5, and 90 deg.
