Conservation of the Mississippi River Watershed has become an important issue that many organizations are undertaking because the capacity of the river to remove nutrients from the water is decreasing and the surrounding ecosystems are being diminished. The Mississippi River Basin encompasses 31 U.S. states with an area of 1,837,000 square ...
The reduction in sediment transported down the Mississippi River is the result of engineering modification of the Mississippi, Missouri, and Ohio rivers and their tributaries by dams, meander cutoffs, river-training structures, and bank revetments and soil erosion control programs in the areas drained by them.
The Mississippi River Delta is slowly sinking due to natural compaction and its sediment supply from up river being greatly diminished by up to 50%, due to dam construction in the Mississippi Basin. [6] The loss of sediment supply has resulted in subsidence of the delta and wetland reduction.
The Mississippi River System, also referred to as the Western Rivers, is a mostly riverine network of the United States which includes the Mississippi River and connecting waterways. The Mississippi River is the largest drainage basin in the United States. [3] In the United States, the Mississippi drains about 41% of the country's rivers. [4]
Bayou Teche was the Mississippi River's main course when it developed a delta about 2,800 to 4,500 years ago. Through a natural process known as deltaic switching , the river's deposits of silt and sediment cause the Mississippi to change its course every thousand years or so.
Wing dam in a man-made river bed. A wing dam or wing dike is a man-made barrier that, unlike a conventional dam, only extends partway into a river.These structures force water into a fast-moving center channel which reduces the rate of sediment accumulation, while slowing water flow near the riverbanks.
The rising Mississippi River tested flood defenses in southeast Iowa and northwest Illinois as it neared forecast crests in the area Monday, driven by a spring surge of water from melting snow.
The Mid-Barataria Sediment Diversion is a $2.3-billion sediment diversion project in the Barataria basin in Louisiana. The project aims to restore river sediment flows into the basin. [1] [2] [3] The intention of the project is to reconnect the Mississipi River and the Barataria basin. [4]
