Louisiana Ecological Forecasting

Louisiana Ecological Forecasting

Using UAVSAR, AVIRIS, and AirSWOT to Examine Historic Trends and Model Sediment Transport within the Wax Lake Delta, Louisiana to Inform Coastal Restoration Efforts

Land loss due to erosion, land subsidence and sea level rise along the Louisiana coast has amounted to 4900 km2 since the 1930s, and an additional 4500 km2 could be lost within 50 years if no action is taken. While most of the coastline is suffering land loss, the Wax Lake Delta has been building at a rate of approximately 5 km2 per year since the early 1970s. This study used remotely sensed and in situ data as well as Deltares Delft3D hydrological modeling software to model water flow and sediment transport in the Wax Lake Delta in order to better understand deltaic sediment dynamics and forecast delta formation. Outputs from the model include modeled sediment transport, water flow and an elevation time series. These outputs will be used to inform coastal research by project partners at the Naval Research Laboratory in Mississippi and the Louisiana Universities Marine Consortium, and to direct restoration projects in areas of the coast where marshes are eroding.
