Flooding Along the Mississippi River: The Impact on the Gulf of Mexico

A record flood along the Mississippi River triggered massive destruction in nine states this spring, total loss exceeding $ 25 billion (Wat, 2011). In most areas, the flood is backwards, but there is concern that, even if it rains, it may cause more floods for saturated lands. When the town began to recover, one thing caused by the flood could not be recovered. Since this area is mainly composed of cultivated land, pollutants such as nitrogen from fertilizer are generated toward the Gulf of Mexico.

This area contains floodplains of the Mississippi River. The Mississippi River enters the Gulf Coast of Mexico, extends north to the Delta at the confluence of the Mississippi and the Ohio River, and extends south to the Gulf of Mexico. In the alluvial valley there are a few of eastern Louisiana, eastern Arkansas, northwest Mississippi, western Tennessee and western Kentucky, Bosel, Missouri, Lower Cash River in Illinois. Non - forest wetlands in the southern part of the floodplain are included in the coastal grassland topography. Water is shaping this land. The valleys, dams, antelope, terraced ridges and recesses are all caused by the floods and floods of the Mississippi River. A slight slight change in altitude will determine the humidity of the site, the plant community growing there, and the habitat of the bird.

The coastal area of ​​Louisiana is at the end of a natural funnel draining 41% of some areas of the United States and Canada. This basin, the Mississippi River basin supplies water to the Gulf of Mexico from the mouth of the Mississippi and Achapharaya Rivers. This coastal area forms more than 11,400 square miles over the past 6,000 formed by various deltas formed by the Mississippi River from the east-west direction of Lafayette to Slidell, forming a wide range of conversion systems and diverse wetlands doing. Landscapes such as freshwater and silt are mixed with coastal processes of the Gulf of Mexico. Cracks of cracks (splits) and addition of sediments to coastal basins along multiple converting areas of periodic river flooding of delta landscape to limited saltwater intrusion of the island
