A conventional riprap revetment or seawall was deemed incompatible with this natural park setting, so the decision was made to construct a cobble berm that resembled the appearance and function of a natural cobble beach, backed by an artificial foredune that was reinforced by a core of sand-filled geotextile bags.
Deposition from overwash (washover) can be deposited onto the beach berm, the dune, or as far as the back barrier bay, marsh, estuary, or lagoon. Sediment deposits created during overwash exhibit consistent scaling — for example, the distance inland that an overwash deposit extends is proportional to the area that the overwash deposit covers.

The berm is the relatively planar [clarification needed] part of the swash zone where the accumulation of sediment occurs at the landward farthest of swash motion (Figure 2). The berm protects the backbeach and coastal dunes from waves but erosion can occur under high energy conditions such as storms. The berm is more easily defined on gravel ...
Not infrequently a whole series of parallel berms is formed, one behind the other. There is a consequent gradual increase in height with the result that, over time, the shoreline advances seawards. A striking example of land-forming system of berms is Skagen Odde on the northern tip of Vendsyssel in the extreme north of Denmark. This headland ...
Physically, the berm is a 2 m (6 ft 7 in) high wall (with a backing trench), which rides along a topographical high point/ridge/hill throughout the territory. Spaced out over every 5 km (3.1 mi) are big, small and medium bases, with approximately 35–40 troops at each observation post and groups of 10 soldiers spaced out over the distance as well.
The removal of sediment from the beach berm and dune thus decreases the beach profile. If storms coincide with unusually high tides, or with a freak wave event such as a tidal surge or tsunami which causes significant coastal flooding, substantial quantities of material may be eroded from the coastal plain or dunes behind the berm by receding ...
“Dune: Part 2” is going viral more than a month before its scheduled release in theaters — for reasons that have nothing to do with the movie. It was the film’s purported promotional ...
To determine this volume, two heights are used, the average low water level (glw) and the height of the dune foot (dv). The height of the dune foot is basically determined by finding the intersection of the steep slope of the dune front and of the dry beach. In general, this theoretical dune foot point will be slightly below the sand.
