Shoreline position is most commonly defined for mapping purposes as

  • A.the seaward edge of the vegetation only
  • B.the position of the deepest of the offshore bars present
  • C.the outer limit of the surf zone
  • D.a specific tidal datum contour or the wet-dry line

Answer: D

Consistency of the definition matters more than which definition is chosen. Comparing positions defined differently is a common source of spurious change in historical analyses. Definition matters more than which one is chosen.
