The Wrack: salt marsh

It is probably a rare coastal beachfront property owner who is not aware that beaches are dynamic systems that erode and accrete in response to storms, sediment supply, rising sea level, and the proximity of sea walls, jetties, and other forms of coastal "armor." Many beachfront owners are also aware that "natural" barrier beaches and their dune systems are able to persist in the face of sea level rise by transgressing, or migrating shoreward.
