Splet01. jan. 2024 · Swash-aligned barriers cannot rollover indefinitely so barrier breakdown will occur (Orford et al. 1996). Sediment may come from rollover incorporation but this is outweighed by sediment loss to the barrier’s extending length. Where sea level is rising the reducing return period associated with extreme water levels means that the barrier is ... SpletA destructive wave is a wave that has a weak swash but a strong backward rush, known as a backwash, which carries the sand and gravel out to sea. ...
