WebThey only form on beaches with a shallow gradient. They form as a simple drainage route for tides. Water flows in and out via the runnel. Berms Spring tides often form a storm ridge which consists of the largest material thrown up by the strong swash of the larger waves. WebA berm is a level space, shelf, or raised barrier (usually made of compacted soil) separating areas in a vertical way, especially partway up a long slope. It can serve as a terrace road, track, path, a fortification line, a border / separation barrier for navigation, good drainage, industry, or other purposes. Etymology [ edit]

WebBeaches - feature of Coastal deposition. Beaches are features of deposition found in coastal areas between high and low tide. They are generally found in areas where there is an inlet or sheltered area, between headlands or a change in the coastline which causes sediment to be trapped and build up.

WebA ridge of sand and shingle formed in the sea in the off-shore zone (from the position of low tide waterline to seaward) lying approximately parallel to the coast is called an offshore bar. An off-shore bar which is exposed due to further addition of sand is termed a barrier bar.

Behind the bar, a lagoon is created, where water has been trapped and the lagoon may gradually be infilled as a salt marsh develops due to it being a low energy zone, which encourages deposition.
