A berm is a nearly horizontal portion that stays dry except during extremely high tides and storms. The swash zone is alternately covered and exposed by wave run-up. The beach face is the sloping section below the berm that is exposed to the swash of the waves. The wrack line (not shown here) is the highest reach of the daily tide where organic and inorganic debris is deposited by wave action. May have sand dunes.[2] (Source)
