Hydrodynamic Modeling Of Newly Emergent Coastal Deltaic Floodplains, Alexandra Christensen
Hydrodynamic Modeling Of Newly Emergent Coastal Deltaic Floodplains, Alexandra Christensen
LSU Master's Theses
Coastal deltaic floodplains provide an important ecosystem service by removing or retaining nitrate from enriched riverine water. Wetland plants, soils, and microbes within these floodplains use nitrate through uptake, burial, and denitrification, thereby reducing the impact of nitrate on algal blooms and hypoxia in the Gulf of Mexico. However, these processes depend on the physical, biological, and chemical conditions within the floodplain. Understanding and characterizing the hydrodynamics of these systems and the relative impact of river, tide, and wind forcings are the first steps in understanding the biogeochemical processes controlling nitrate removal. Motivated by the desire to identify biogeochemical hotspots …
