It’s one of the most famous rivers in the world, and for plenty of interesting reasons. Read on to find out why. Where is the Mississippi River. The Mississippi River is about 2, miles (3, kilometers) long. The Mississippi River is the second-longest river and chief river of the second-largest drainage system on the North American continent, second only to the Hudson Bay drainage system.
From its traditional source of Lake Itasca in northern Minnesota, it flows generally south for 2, miles (3, km) to the Mississippi River Delta in the Gulf of Mexico.

Louisiana’s Mississippi River Delta and coast have made headlines of late, thanks to a pair of studies that examine flooding and coastal erosion, a state-issued coastal quarantine and the recently-announced accelerated permitting for a linchpin project in Louisiana’s master plan to restore and preserve its coast.

Learn vocabulary, terms, and more with flashcards, games, and other study tools. This review synthesizes the knowledge regarding the environmental forces affecting water level variability in the coastal waters of the Mississippi River delta and relates these fluctuations to.
Introduction. The Louisiana continental shelf (LCS) is strongly impacted by the discharge of the Mississippi and Atchafalaya River Basin.
Two thirds of the Mississippi River flow enters the Gulf of Mexico through the Mississippi River bird-foot delta, whereas the remaining third is delivered from the Atchafalaya River ().Delivery of organic matter to the LCS can be allochthonous export by Cited by: 8.

The river contributes 90% of the freshwater loading to the Gulf of Mexico. The Mississippi River Delta and coastal Louisiana are disappearing at an astonishing rate: a football field of wetlands vanishes into open water every minutes.
Since the s, Louisiana has lost over 2, square miles of land, an area roughly the size of Delaware. Mississippi River mouth processes: Effluent dynamics and morphologic development (Technical report / Coastal Studies Institute, Louisiana State University) [Wright, L.

Upper Mississippi, Lower Mississippi, and Ohio basins contributed the largest amounts of nutrients delivered to the Gulf. The high delivery areas near the Mississippi River main stem, from which 87% of N and 90% of P was predicted to reach the Gulf, also coincided with elevated nutrient yields to local waters.
The Louisiana Department of Natural Resources, Office of Coastal Management has produced an educational video "Rainwater Blues" about what you can do to help keep Louisiana's waters clean.
This video is an especially good educational tool for teachers and civic leaders and is ideal for showing in natural science classrooms, environmental. diversions in coastal Louisiana may be complicated by changes in water quality of the Mississippi River since the turn of the twentieth century, when the river last regularly overﬂowed its banks unencumbered by ﬂood-control levees.

To help evaluate effects of Mississippi River inputs to sustainability of coastal Louisiana ecosystems, we compared porewater and substrate quality of organic-rich Panicum hemitomon freshwater marshes inundated by river water annually for more than 30 years (Penchant basin, PB) or not during the same time (Barataria basin, BB).
In the marshes receiving river water the soil environment was more. History. The Mississippi River originates as a tiny outlet stream from Lake Itasca in northern Minnesota. During a meandering 2, mile journey south to the Gulf of Mexico, the Mississippi River is joined by hundreds of tributaries, including the Ohio and Missouri Rivers.

Selected trace elements (TEs), dissolved organic carbon, and nutrients were studied in Louisiana Shelf waters including the Mississippi (MR) and Atchafalaya (AR) River plumes during periods of high, intermediate, and low river discharges.
Seasonal variations in TEs were observed at low salinity, reflecting seasonal changes in the riverAuthor: DongJoo Joung. Mississippi River water quality is of paramount importance for the sustainability of these values and uses. However, many different human activities across the Mississippi River basin affect water quality.
These include manufacturing, urbanization, timber harvesting, and agriculture. Locks, dams,File Size: KB. sources. The Mississippi River delivers approxi- mately 2 X g yr-I of particulate organic carbon (POC) to the Gulf (Malcolm and Durum ).
In addition, these neardelta sediments receive mate- rials from coastal primary production enhanced by terrestrial nutrient inputs.
Near the river mouth. Nutrients and freshwater delivered by the Mississippi and Atchafalaya Rivers drive algal production in the northern Gulf of Mexico, which eventually results in the widespread occurrence of hypoxic bottom waters along the Louisiana and Texas coast.
Researchers have demonstrated a relation between the extent of the hypoxic zone and the magnitude of streamflow, nutrient fluxes, and nutrient. Mississippi River Delta wetlands is the separation of the wetlands from the river and its sediment due to control structures and channel stabilization.
Diversions may deliver mineral sediment directly to marsh surfaces, increasing rates of accretion and/or freshwater and nutrients toFile Size: KB. The general area of interest in this study is the stretch of the Mississippi River main stem from the Louisiana-Mississippi state line, River Mile (R.M.)to the Head of Passes at River Mile 0.
The Head of Passes is the point at which the Mississippi divides into three channels and the delta begins. It is joined by the Missouri River north of St. Louis and receives the waters of the Ohio River at Cairo, Illinois. Here it becomes the Lower Mississippi, a river giant, unequaled among American waters.
