Description
Definition A gently sloping zone formed by unconsolidated material at the shoreline, typically with a concave profile. This zone extends landward from the low-water line to either (a) the place where there is a definite change in material or physiographic form (such as a cliff) or (b) the line of permanent vegetation. Only those portions of the beach within the splash zone would be within the CMECS system; areas of the beach further inland are terrestrial systems.
