Capacity Of Freshwater Marsh To Process Nutrients In Diverted Mississippi River Water, Craig Bonya' Johnson
Capacity Of Freshwater Marsh To Process Nutrients In Diverted Mississippi River Water, Craig Bonya' Johnson
LSU Master's Theses
The loss of Louisiana's coastal wetlands has mandated the construction of diversion structures for reintroduction of a portion of the Mississippi River into Louisiana's coastal region for slowing or reversing marsh deterioration. The Davis Pond Freshwater Diversion Structure allows for a section of the Mississippi River water to be reintroduced into Louisiana's Barataria Basin. The reintroduced Mississippi River water contains elevated levels of nitrate and other nutrients from agricultural runoff primarily from the upper reaches of the Mississippi River drainage basin. These elevated nitrate levels have raised questions of possible eutrophication effects on Louisiana estuaries. The purpose of this study …

Bacterial Plume Dynamics In The Marshland Upwelling System Employed In The Near Freshwater Conditions, Benjamin Kojo Addo
LSU Master's Theses
The marshland upwelling system (MUS) was installed in a floatation marsh along the banks of the Bayou Segnette Waterway, Louisiana. This site was characterized by native groundwater of low salinity regime. Previous studies focused on the removal of fecal pathogens from settled/raw and secondarily treated wastewater under high saline groundwater conditions. The objectives of this research were to: 1) quantify the impact of natural die-off on bacterial removal within the MUS, 2) determine bacterial retardation rates in laboratory-repacked sandy loam soil columns, and 3) evaluate the effectiveness of the MUS in removing fecal pathogens from settled, raw wastewater. Varying salinities …
