Renourished Beaches Are Problematic, #2

"Ironically, beach nourishment projects themselves can be a source of erosion for neighboring areas. That is because a beach built out on the coast puts a bulge in the shoreline that can cause a so-called erosion shadow downdrift. This bulge of sand acts much like a groin, altering the longshore transport by trapping sand updrift and, in effect, starving the area downdrift." (Excerpt from the book, Against the Tide, by Cornelia Dean, Columbia University Press, 1999, pg. 114)
