Another possibility is that sand is transported from shoals. As the bars developed vertically, they gradually rose above sea level, forming barrier islands. Cities such as Miami Beach and Atlantic City are on barrier islands. Wind and plants such as sea oats form dunes, but occasionally dunes are inundated by high water and may be reworked by storm surges and waves.
The formation of an island allows other landforms to develop, each characterized by its dominant sediment type and by the water that shapes them. Submit Tips For Editing We welcome suggested improvements to any of our articles.

In September Hurricane Ike caused moderate damage to the island. Many multistory resort hotels and condominiums have been erected along the coastline of the Gulf of Mexico.
Sand washover fans in the lagoons are evidence of rolling over. Tidal inlets also provide a path for high water during storms and hurricanes. Barrier islands are dynamic systems that migrate under the influence of changing sea levels, storms, waves, tides, and longshore currents.

This is accomplished by beach hardening the construction of engineered barriers or beach nourishment the continual replacement of sand that has been washed away during storms. Finally, the waves, tides and currents in the area of a future barrier island must be strong enough to move the sand.
Short islands were joined to form today's longer islands.
In contrast, wave-dominated areas form long barrier islands with narrow bays and narrow, shallow inlets. South Padre Island has been in a destructive phase for a long time, probably having retreated landward along with the lagoon and mainland shoreline.
