dc.description.abstractMonitoring Completed Navigation Projects (MCNP) Program evaluates the structural and functional performance of existing navigation structures. Under Periodic Inspections, aerial photography, ground-truth surveys, walking inspections, photogrammetry, and lidar elevation data are used to periodically assess the structural conditions of selected structures. A database of these structures is being compiled for asset management and other purposes. Cleveland Harbor East Breakwater, OH, has sustained extensive damage since its construction in 1915. The Breakwater has had an extensive repair history, including a major rehabilitation in 1979–80 involving the placement of 2-ton dolosse on the lakeward slope and crest of the easterly 4,400 feet (ft). Some failed and were replaced with 4-ton dolosse. Other repairs took place in 1986, 1989, 1991, and 2001 on the nondolos sections. Burns Harbor North Breakwater, IN, is a 4,640 ft rubble-mound structure constructed in 1969. The Breakwater has required extensive maintenance including the addition of 290 kilotons of stone through 1989. A submerged reef was constructed between 1995 and 1998, 75 ft lakeward of the Breakwater, to reduce wave energy reaching the structure. Records indicate that 1,128 broken and/or cracked dolosse, and 282 damaged armor stones, were documented during the 2006 Periodic Inspections of Cleveland Harbor East Breakwater and Burns Harbor North Breakwater, respectively. This interim data report contains a precise record of dolos and stone armor damage existing in July 2006 on these structures. A comprehensive analysis and technical report correlating this damage with storm and water level conditions will be published at a later date as subsequent additional field data are obtained at these two Great Lakes breakwaters.-
