Abstract: An undistorted-scale hydraulic model study was conducted to investigate the armor stability and wave-transmission design of three breakwater cross sections for Port Ontario Harbor, New York. Plan 1 was constructed to a crown elevation of +10 ft lwd and used armor slopes of 1V on 2H and 1V on 1.5H lakeside and harbor side, respectively. A crown width of 16 ft, equivalent to three armor-stone diameters, was used and the slopes and crown were armored with two thicknesses of 7.8-ton stone. Plan 1A was the same as Plan 1 except that the crown elevation was lowered to +9 ft lwd. Plan 2 was similar to Plan 1 except that the armor weight was reduced to 5.3 tons and the crown width was narrowed to 14 ft. Based on results of model tests, it was concluded that Plans 1 and 2 meet the designated wave-transmission criteria of significant transmitted wave height < 3.0 ft and are stable designs for the maximum breaking wave heights that can be produced in the model for 7- to 11-sec waves at swl's of +1.0 and +4.6 ft lwd. Plan 1 exhibited the best stability response of all three plans investigated. Maximum significant transmitted wave heights were 2.5, 3.0 and 2.4 ft for Plans 1, 1A, and 2, respectively.
