Barrier islands. A barrier island is a long, thin, sandy stretch of land, oriented parallel to the mainland coast that protects the coast from the full force of powerful storm waves. Between the barrier island and the mainland is a calm, protected water body such as a lagoon or bay. Barrier islands are dynamic systems, constantly on the move, migrating under the influence of changing sea levels, storms, waves, tides , and longshore currents.
Barrier islands are long, relatively narrow islands that run along a coast parallel to the mainland. They are built up by the action of waves and currents and help protect the coastline from erosion by surf and tidal surges.he amount of sand in a barrier island system changes with time. Normal waves tend to push more sand onto the islands. These low-angle waves bring in sand from out in the shallow off-shore region which accumulates in the intertidal area.
