| dc.description.abstract | After traveling up the eastern U.S. coastline, Hurricane Sandy made landfall on 29 October 2012 near Atlantic City, NJ, with winds of 80 mph. The backside of the storm moved inland, bringing high winds and rain far into the nation’s interior. No longer a hurricane, but termed Superstorm Sandy, the winds were generally from the north over the Great Lakes, extending as far west as Lake Michigan, causing extensive damage to several federal harbor structures especially in the Lower Great Lakes, including Cleveland East Breakwater on Lake Erie and Oswego Detached Breakwater on Lake Ontario. Concrete dolos armor units were selected to repair damage on these two structures. During 2015, 6,919 6.5-ton unreinforced dolosse were placed, and an additional 11,340 dolosse were placed in 2016 on the Cleveland East Breakwater. During 2015, 973 16-ton steel-reinforced dolosse were placed on the Oswego Detached Breakwater. The dolos design process, creation of the forms, strength testing, and placement are described and documented. Knowledge gained from this initial placement and from future periodic monitoring will correlate dolos movement with environmental forces. This information will be used for reliability analysis of coastal structures in determining remaining useful life for asset-management funding prioritizations. | en_US |
