The 1973 Flood and Man's Constriction of the Mississippi River.
The progressive constriction of the Mississippi for navigation since 1837 has caused bottom erosion in some stretches. In others the bottom oscillates up and down with time. The high stages rise much more rapidly. Constriction of the river channel causes flooding and makes floods higher; thus navigation works degrade the protection afforded by levees. The combination of navigation works and lev...
متن کاملNutrient delivery from the Mississippi River to the Gulf of Mexico and effects of cropland conservation
Excessive nutrients transported from the Mississippi River Basin (MRB) have created a hypoxic zone within the Gulf of Mexico, with numerous negative ecological effects. Furthermore, federal expenditures on agricultural conservation practices have received intense scrutiny in recent years. Partly driven by these factors, the USDA Conservation Effects Assessment Project (CEAP) recently completed ...
متن کاملThe Role of the Mississippi River in Gulf of Mexico Hypoxia Oversimplifications and Confusion
A report produced for The Fertilizer Institute by the University of Alabama entitled The Role of the Mississippi River in the Gulf of Mexico Hypoxia raises several questions about whether the large-scale oxygen depletion (hypoxia) in bottom waters of the Louisiana continental shelf is the result of anthropogenic nutrient loading from the Mississippi River, as has been reported in the scientific...
متن کاملPredicting the response of Gulf of Mexico hypoxia to variations in Mississippi River nitrogen load
The effects of nutrient loading from the Mississippi River basin on the areal extent of hypoxia in the northern Gulf of Mexico were examined using a novel application of a dissolved oxygen model for a river. The model, driven by river nitrogen load and a simple parameterization of ocean dynamics, reproduced 17 yr of observed hypoxia location and extent, subpycnocline oxygen consumption, and cro...
متن کاملCahokia's emergence and decline coincided with shifts of flood frequency on the Mississippi River.
Here we establish the timing of major flood events of the central Mississippi River over the last 1,800 y, using floodwater sediments deposited in two floodplain lakes. Shifts in the frequency of high-magnitude floods are mediated by moisture availability over midcontinental North America and correspond to the emergence and decline of Cahokia--a major late prehistoric settlement in the Mississi...
