From page 148...
... Natural accretion is the buildup of land, solely by the action of the forces of nature, on a beach by deposition of water or airborne material. Artificial accretion is a similar buildup of land by human actions, such as accretion formed by a groin, breakwater, or beach fill deposited by mechanical means.
