This situation can lead to overwash, which brings sand from the front of the island to the top and/or landward side of the island. This process leads to the evolution and migration of the barrier island. Critical width concept

Web23 dec. 2024 · Barrier island response to sea-level rise depends on their ability to transgress and move sediment onto and behind the barrier, either through flood-tidal delta deposition or via overwash. Our understanding of these processes over decadal or longer timescales, however, is limited. WebWhere the barrier is backed by an unconstrained broad lagoon or bay, inlets may migrate alongshore in the direction of net longshore transport. Other inlets may be temporary, being opened during a large storm and closing due to infilling in a few months or years.
