The backshore area of a beach extends from the limit of high water foam lines to dunes or extreme inland limit of the beach.[1] It is only affected by waves during exceptional high tides or severe storms.[2]

Sediments in this area are well-sorted and well-rounded. Its grain sizes are mainly coarse sand and medium sand, which are larger than that in littoral barrier dune. The sedimentary structures include parallel bedding and low-angle cross-bedding.
