Abstract: Port Washington Harbor is exposed to waves generated by storms from northeast to south-southeast. Storm waves from these directions have caused damage to harbor facilities and boats and difficulties to ships and craft navigating the harbor entrance. Standing waves in the slip areas have reached heights of 12 ft. Anchorage in the outer harbor is not safe for small boats due to lack of adequate wave protection. Hence, the harbor is unsafe as a harbor-of-refuge. Consequently, there is no harbor-of-refuge between Milwaukee and Sheboygan, a distance of 56 miles. Also, Port Washington Harbor does not have adequately protected permanent mooring and docking facilities to accommodate the demand for such facilities in this area. Hydraulic model tests were conducted to determine the effects of installation of Igloo wave absorber units in the harbor. Conclusions drawn from the results of these tests were that (A.) Igloo wave absorber units placed in and around the slip areas will significantly reduce wave heights in the slips; (B.) east and west breakwaters constructed of Igloo units without backing will not be stable; (C.) a 500-ft-long Igloo structure adjacent to the nort h breakwater as an alternative to the east breakwater will not meet established wave-height criteria; and (D.) a 200-ft-long Igloo east breakwater (with backing) will meet the established \vave-height criteria.
