13. ABSTRACT /Maximum 200 words) 



A two-dimensional model study of the damaged Burns Waterway Harbor breakwater was conducted. The 1 : 36 -scale 

 undistorted flume tests were used to evaluate various repair options that included placing a submerged breakwater lake- 

 ward of the existing breakwater, attaching a berm breakwater to the lakeside of the structure, the addition of an 18-ton 

 angular stone overlay, and reworking the existing stone into special placement at the crest. 



Generally, the submerged breakwater and restacking of the existing armor were the least effective approaches to 

 reducing wave transmission; whereas the toe berms and large-stone overlays were the most effective. However, the 

 submerged reefs proved to be the most effective in reducing or eliminating damage to the existing breakwater.
