Man made causes on beach erosion

For example, along northern in the altogether Jersey, 11 shore line surveys were conducted between 1853 and 1985. Analyses of that data has revealed that the ara's bankes are retreating at a mean identify of 0.8 meters/year (Gorman & Reed, 1989, p. 122). invasion of the land by the sea, or nautical transgression, may spend as a result of either sea take rise or coastal subsidence. It has been estimated that mean sea levels in the United States are rising at a rate of about 1 foot every 100 years (Westgate, 1983, p. 105); moreover, in smart Jersey, sea levels are up 17 inches since 1900, and the rate of rise seems to be accelerating (Bennett, 1993, p. 132).

Even small changes in sea level may have catastrophic consequences for coastal environments. On Long Island, topographical features are generally of abject relief and gentle slope. much(prenominal) geomorphology renders the island vulnerable to marine subjects. According to the Bruun theory, rising sea levels cause erosion when they dispatch upper beach material and deposited it on nearshore bottoms. This process displaces the beach profile shoreward (Schwartz, 1967, p. 76).

Additional factors which may affect shore lines hold the following: coastal structures, storm activity, and sediment starvation. Commercial festering can significantly alter a barrier island (Gorman & Reed, 1989, p. 122). For example, sometimes structures are built in front of the dune line. Such development may not only be adversely affected by advancing storms,

The effect that this environmental change is having on wildlife is unknown.

The area in and around Long Island is home to numerous forms of wildlife. Marine animals allow sharks, whales, turtles, and dolphins (Gast, 1990, p. 54). In addition, gulls and terns are also abundant (Pendick, 1990, p. 43). In fact, the erosion may actually be having a beneficial effect on resident animals. For example, Cupsogue County Park has been isolated from the public by inlets for many years now. This now deserted beach could conceivably provide undisturbed natural habitat for a bod of species (Lyall, 1991, p. B4).
