A storm profile differs from a swell profile in that the storm profile has

  • A.a steeper beach face with a well developed berm
  • B.no sediment movement of any kind
  • C.sediment that has been moved permanently out of the littoral system
  • D.a flatter beach face with sediment moved to an offshore bar

Answer: D

Steep short period storm waves carry sand seaward into a bar, flattening the face. The sand is not lost, and long swell waves return it to the beach over the following weeks. The exchange is largely reversible within a season.
