Atchafalaya: River Control :: essays research papers

The Atchafalaya is the most original basins because it has a ontogeny system with very stable wetlands. It is also the biggest river swamp in pairing America further has lost about 3,760 domain between 1932 and 1990. The discharge of the wetlands is primarily due to erosion, human activities, and natural conversion. Many human activities, much(prenominal) as oil and gas pipelines, have interrupted the movement of commingle and sediment within the wetlands that it is another factor in the loss of acres for the Atchafalaya. But there is not a total loss in this, the Atchafalaya have also positive outlooks on things. The basin consists of more search comp ard to any other natural water system in northbound America. Let alone the production and distribution of tether types of crawfish fix in Atchafalaya. The crawfish is the main fundsmaker for New Orleans fish markets. But the crawfish may only resemble 10-20% of what is caught. Most of it results in bycatch, organisms caugh t in the shrimp nets that are discarded, and the Atchafalaya is seen some times as a floating graveyard of different expired species.Unfortunately, natural delta growth has been hampered by dredging activities along the main navigation channel. Dredge materials have been placed along side the channel, there by choking off the natural give of fresh water and sediment to the marsh. TO solve this problem Atchafalaya sediment projects were designed to restore fresh water and sediment delivery processes to the Atchafalaya delta. Within 20 years, this is expected to create an additional 3,000 acres of wetland habitat.Out of the 50,000 acres of Atchafalaya, three fourths of it is privately owned. The only way this is determined is if the land accretes from the shore of a lake or a bayou, it is the property of an owner. But if the land accretes as an island, the ground owns it making it an imbalance between government and private landowners. Most landowners are not looking at Atchafalaya as a historical landmark, but for what is worth under the waters surface as money value. These wetlands support a 1 billion dollar annual fishery industry, therefore making these wetlands a positive outlook on the commerce opportunities for the Louisiana people. Many fishermen make a living off of the naval species inhabiting the Atchafalaya. But the employment for this occupation is decreasing because of the land loss. Making it rocky for fishermen to understand what is government owned and what is privately owned.
