Reef Breakwater Wave-Attenuation and Stability Tests, Burns Waterway Harbor, Indiana
A two-dimensional model study of a proposed reef breakwater for protection of the existing, damage-prone, rubble-mound breakwater at Burns Waterway Harbor was conducted. Sufficient 1:36-scale undistorted flume tests were conducted such that an optimum submerged reef could be selected. Specifically, it was desired to quantify performance (stability/transmission response) in terms of structure height and width, location relative to the existing breakwater, and stone size and gradation. Seven improvement plans were considered. All significantly improved stability of the existing breakwater and reduced transmitted wave heights to some extent. Test results for the various improvement plans showed that all structures tested were successful in reducing 7- and 9-sec, 5-ft incident waves to heights of 1 ft or less behind the existing breakwater. Also, as desired, wave heights of about 15 ft or less were observed behind the reef for 11.6-sec, 19-ft incident waves, thus eliminating most damage to the existing breakwater. Five-ton armor stone was completely stable at crest elevations of -10 and -20 ft low-water datum. Increasing the toe-to-toe spacing of the reef from the existing breakwater from 75 to 100 ft slightly improved stability of the existing structure and slightly increased lransmission.
