Splet29. okt. 2003 · Swash aligned beaches •Swash aligned beaches are where wave crests (top of wave) are parallel to the beach alignment. •The waves come into the shore at 90 degrees so there is little lateral displacement. The waves wash up the beach and then swash back down the beach. •There is therefore no net longshore drift. See drift aligned beaches SpletA ' swash aligned ' beach brings in waves parallel to the shore, building up large beaches. They are also associated with constructive waves, known for depositing material rather than eroding the cliffs. 'Swash Aligned' beaches are associated with large beach profiles, with dunes, berms and drainage features.
SpletIn geography, swash, or forewash, is a turbulent layer of water that wash up on the beach after an incoming wave breaks. The swash action can move beach materials up and … http://thebritishgeographer.weebly.com/coasts-of-erosion-and-coasts-of-deposition.html
Splet11. maj 2014 · Swash aligned beaches (e.g. Hell’s Mouth) are produced where the waves break in line (parallel) with the coast. Swash & backwash movements move material up … SpletIn small areas of sea or coastlines that are protected by seaward barriers or islands, prevailing winds do not affect wind direction; thus, waves approaching the coast are parallel to the shore, known as swash-aligned. Swash-aligned shorelines develop large beaches with potential dunes that provide protection from erosion.
