Photos representing the three types of coastal change

Photos representing the three types of coastal change: collision, overwash, and inundation. Left: Waves and surge during Hurricane Sandy (October 2012) eroded the dunes and caused structural failure in Westerly, Rhode Island. (Photo credit: National Weather Service, Taunton, Massachusetts.) Center: Waves and surge during Hurricane Isaac (August 2012) overtopped low dunes to create overwash deposits that extended onto the road and the island in lobes toward the bay side of Dauphin Island, Alabama. Right: Waves and surge during Hurricane Sandy cut through a narrow portion of Fire Island, New York to create a new inlet.
