Beach Protection

The barrier islands that make up the Outer Banks of North Carolina are composed of sand. This sand is in near constant movement, resulting in an ever-changing shoreline—a process witnessed by anyone who observes the beach on a regular basis. The normal action of winds, waves, tides, and storms reduces the depth of the beach and erodes the dunes. Long-term records have documented the loss of shoreline along parts of Bogue Banks between 1936 and 1994 to be 120 ft., averaging 1 to 3 feet per year. As these islands change from uninhabited to populated, the erosion part of shoreline dynamics becomes an issue.
