A spatial analysis of phosphorus in the Mississippi River Basin
Phosphorus (P) in rivers and streams in the Mississippi River Basin (MRB) is a contributing nutrient to hypoxia in the Gulf of Mexico and impacts local water quality. Although nitrogen has been extensively studied and attributed to be the main nutrient causing the Gulf hypoxic zone, P has …

Cahokia's origins: Religion, complexity and ridge-top mortuaries in the Mississippi River Valley
… religion and complexity as it influenced the emergence of the city of Cahokia through an exploration of ridge-top mortuary practices across the three precincts of Cahokia, East St. Louis and St. Louis ca. AD 1050-1200. Through the theoretical lens of relational ontology and ‘New Animism’ I …

The Mississippi River Delta Basin and Why We are Failing to Save its Wetlands
Every thousand years or so, when the Mississippi River's sediment load lengthened and blocked the River’s route to the Gulf of Mexico, the mother stream changed course completely, finding a shorter route to the sea. Then, it built a new delta, thus spreading the gift of land creation along a wide …

A GIS Approach to Modeling Groundwater Levels in the Mississippi River Valley Alluvial Aquifer
… may lead to future economic challenges for the Arkansas Delta region. The Mississippi River Valley Alluvial Aquifer is the uppermost aquifer and features the largest groundwater capacity in the Mississippi Embayment Aquifer System. The Mississippi River Valley Alluvial Aquifer, commonly …

Deconstructing the Mississippi River : restoring a continental system through the integration of flexible infrastructure
The most prevalent social and economic issues plaguing cities are symptomatic of much bigger underlying environmental problems. Cities are governed by legislation set within artificial political boundaries, however ecology systems surpass and are not restricted by these boundaries. The decisions …

Utilizing archival data to assess historic changes in flood flow conveyance of the Mississippi River
The assessment of change in river systems requires reference conditions. However, most large navigable waterways in the United States and elsewhere around the world have a wealth of archival data because of past engineering projects and flood control efforts. For example, in the United States, …

Regionalism and Universality on the Big Muddy: A Trail of Pavilions along the Mississippi River
For over 2,500 miles, the Mississippi passes through distinct regions, each with unique climatic, cultural, geologic, and ecological traits. This thesis proposes a trail of pavilions along the full length of the Mississippi to encourage exploration of the river's diverse settings and cultures. A …

Linking nitrogen biogeochemistry to different stages of wetland soil development in the Mississippi River Delta, Louisiana
… nutrient-enhanced eutrophication occur across the Mississippi River delta and include newly emergent landscapes, in the early stages of ecological succession, and older landscape formations, with fully developed ecological communities. Here I tested how the anthropogenic effects of a …

Bighead and silver carp hybridization in the Mississippi River Basin: prevalence, distribution, and post-zygotic selection
… in plant and animal taxa. Understanding the evolutionary consequences of hybridization is dependent upon the ability to adequately detect genetically admixed individuals, characterize the maternal contribution and structure of hybrid zones, and understand post-zygotic selection acting on …

Subaqueous, hurricane-initiated shelf failure morphodynamics along the Mississippi River Delta Front, north-central Gulf of Mexico
<p>Seafloor instability along the Mississippi River Delta Front (MRDF) gained renewed attention with the landfall of Hurricanes Ivan (2004) and Katrina (2005). Traditional root causes for MRDF shelf failure were exacerbated by sea-state conditions associated with these severe tropical cyclones and …

Characterizing Variable Flow Pathways And Geochemical History Of Seepage Under The Mississippi River Levee: 2011, 2015, And 2016 Floods
… when piping occurs, creating channels beneath the levee and forming sand boils where transported sediments discharge. Along the lower Mississippi River, pathways beneath the levee vary with surface geology, following deeper paths where the levee overlies channel fill deposits, and shallower …

Radiocarbon reservoir effects in the American bottom flood plain of the Mississippi River and adjacent uplands in southern Illinois
Radiocarbon reservoir effects (RREs) occur when the 14C activity in a system does not maintain equilibrium with atmospheric 14CO2 activity. Within aquatic systems, old (14C-depleted) carbon may dilute the current carbon pool by soil erosion, decomposition of old botanical and fauna remains, and …

Nitrogen and Carbon Export to the Gulf of Mexico by the Atchafalaya River, a Major Distributary of the Mississippi River
Summer hypoxia in the Northern Gulf of Mexico has been attributed to large nutrient inputs, especially nitrate-nitrogen, from the Mississippi-Atchafalaya River system. The 2008 Gulf Hypoxia Action Plan calls for river corridor wetland restoration to reduce nitrate loads, but it is largely unknown …

Analysis of water volume change of the lakes and reservoirs in the Mississippi River basin using Landsat imagery and satellite altimetry
In recent years, the demand for freshwater has been steadily increasing owing to population growth and economic expansion. Surface waters such as lakes and reservoirs function as a dominant factor in mankind's freshwater provision. Analysis of changes in their water storage is consequently vital …

Evaluating Commodity Farm Program Selection and Economic Return Variability on Representative Farms in the Mississippi River Delta Region Using a Risk Return Framework
The Agricultural Act of 2014, signed February 7, 2014, introduces a new era of federal support in the production of major agricultural commodities in the United States for the 2014 through 2018 crop years. The ultimate result of the Act was a 954-page piece of legislation that represented …
