Why Shore Armoring Inevitably Fails

In this short film, Professor Guy Meadows (Great Lakes Research Center, Michigan Technological University) describes how high-water levels and waves are changing the shorelines of the Great Lakes through a constant process of erosion, movement, and deposition. Shore structures installed to stop erosion such as revetments may block the erosive forces of Lake Michigan’s waves and high waters for a time, but they ultimately succumb and collapse. Research and observation make it clear, Meadows says, that “every one of these structures causes more erosion in the long term than they prevent in the short term.”
