Backshore definition
Backshore means a berm, together with associated marshes or meadows, on marine shores landward of the ordinary high water mark which is normally above high tide level and has been gradually built up by accretion.
Backshore means the accretion or erosion zone, located landward of the line of ordinary high water, which is normally wetted only by storm tides. A backshore may take the form of a more or less narrow storm berm (ridge of wave-heaped sand and/or gravel) under a bluff, or it may constitute a broader complex of berms, marshes, meadows, or dunes landward of the line of ordinary high water. It is part of the littoral drift process along its waterward boundary.a zone of accretion or erosion lying landward of the average high-tide mark, wetted by tides during storm events.
