Breakwater and Revetment Stability Study, San Juan National Historic Site, San Juan, Puerto Rico. Hydraulic Model Investigation
A hydraulic model investigation was conducted using both two-dimensional and three-dimensional stability models at undistorted linear scales (model to prototype) of 1:38.5 and 1:50.5, respectively. The purposes of the stability tests were as follows: (a) Develop stable, economical and aesthetically pleasing designs for the offshore breakwater, north revetment, and west revetment to protect the San Juan National Historical Site from storm conditions that would generate depth-limited breaking waves at still-water levels (swl's) of 0.0 and +1.9 ft msl. (b) With the protective structures in place, determine the runup produced on the north and west slopes when exposed to a range of wave heights with wave periods from 7 to 17 sec at swl's of 0.0 and/or +1.9. (c) Both with and without the offshore breakwater and north revetment in place, expose the construction trestle to a range of wave periods and wave heights at swl's of 0.0 and +1.9 to observe the impact of the combined incident and reflected waves on the trestle and support pilings. Test results indicated that a two-layer system of 28-ton armor stone, placed on a 1V-on-2H slope using random replacement, would be an adequate design for the offshore breakwater.
