WebFor particularly extreme events, this net loss of sediment might extend across the entire active beach profile, that is from the dune or cliff maxima down to a depth of negligible beach profile change known as the depth of closure. Such an immense loss of sediment may take decades for the beach system to recover from, if at all.

WebJul 7, 2024 · If the swash is stronger than the backwash (constructive wave), some of the sediment carried in the wave will be left behind to build up the beach. This means that the beach increases in size. If the swash is weaker than the backwash (destructive wave), very little sediment is carried up the beach. What causes a steep beach profile?
