Do North Carolinas ocean beaches experience “long-term” erosion?
Yes. Long-term erosion can be caused by a variety of factors, including rising sea levels. The ocean has risen about 6 inches during the last century, causing North Carolina’s barrier islands to migrate landward. Although this process can cause erosion along the entire oceanfront, areas adjacent to inlets are often the most profoundly affected. Some “migrating inlets” are constantly moving in one direction. Others may stay in the same general location but expand and contract constantly. These inlets are often called “oscillating inlets.” In addition to its natural causes, erosion can be set in motion by human activities. For example, a jetty constructed to stabilize an inlet or a structure built to stabilize a beach can trap sand on one side but increase erosion on the other. Such erosion will continue until the structure is removed or the beach adjusts. back-to-top What is the typical erosion rate of a North Carolina shoreline? Studies by the N.C.
