An innovative breakwater concept consisting of a conventional breakwater and a submerged-reef breakwater operating in tandem has been designed for the southern end of Lake Michigan. The tandem breakwater system was found to cost $1 million less to build than a single structure designed to meet the same operating criteria. Because of the depth-limiting behavior of the reef, the tandem design possesses a lower design risk for extreme events. This paper provides a summary of the design development and physical model testing results for the concept.
