History of Eastern United States Coast Barrier Islands Research Paper

History of Eastern united States soaring bar Islands - Research Paper ExampleThe Native Americans first occupied these barrier islands. They were afterward taken over by the European settlers for their recreational and touristic pursuits. However, they have diminished in size and move back in the past years due to rising sea level, diminishing sediment, storms, and gentle interference. Extensive human settlement in these argonas has raised concerns regarding the loss of habitat. Although vulner equal, these barrier islands are very important economically, serving as areas for tourist development, the source of food, and employment.

They usually create chains situated a number of miles offshore alongside the more passive margins. The back barrier region separates the barrier island from the mainland and shallow bays, marshes, estuaries, or lagoons usually occupy it. Barriers are created by the vertical accumulation of the sand from wind and waves action. Barrier islands are called so because they signify the shoreline natural protection from the forces of tsunamis, tides, currents, and waves from the core ocean. However, the majority of the barrier islands have been moody into resort-type living and beautiful beaches (Kusky 2008, 5). The development of the barrier islands characterizes one o f the most dangerous trends in the coastal zones. This is because barriers are jutted mobile strips of sand moving in response to the changing storms, tides, coastal currents, and sea levels. Storms are able to move the complete sandy substrate out from the underneath of the tall buildings. Kusky (2008, 6) states that the size of barrier islands ranges from delineate and discontinuous strips of sand that may be only a few hundred feet wide, too enlarged islands that extend many miles across and also in length. The length and the width are calculated from the alert amount of sediment and the balance between the tidal and wave energy. Majority of the barriers are built from sand (sand from the eroded coastal cliffs, deposited by rivers along the delta systems or sand left from the glaciations). Barrier islands are sibylline to be discontinuous to permit water from the tidal changes to get back to the sea along the tidal inlets systems (Kusky 2008, 6). The sub-environments of barri er islands are classified the same as those of beaches. These sub-environments include barrier interior, landward interior, and the beach. The beach pillowcase of the barrier is the most vibrant section of the island. It absorbs energy from the tides and waves and responds much like the mainland beaches. The beach backside of many barrier islands are marked by a foredune ridge or along frontal, followed landward by the secondary dunes.
