Water Injection Dredging in the United States
Effects from Thin-Layer Disposal of Dredged Material on Water Quality in Mississippi Sound
Recycling on the Mississippi
Changes in the Mississippi River's water depth and alignment are forcing the retirement of the 105-year-old Hannibal, Mo. swing bridge. Although the bridge's...
Seismic Rehabilitation of Sardis Dam
Extensive subsurface investigation of the embankment dam revealed the existence of a weak layer of silt and soft clay in the original topstratum clay underlaying the upstream shell of...
Storm Water Management in the Greater New Orleans Area
Two parishes, Orleans and Jefferson, located within the Greater New Orleans area have been identified by EPA as urbanized areas requiring storm water permits. Storm water management has...
Processes Affecting Coastal Wetland Loss in the Louisiana Deltaic Plain
Nowhere are the problems of coastal wetland loss more serious and dramatic than in the Mississippi River deltaic plain region of south-central Louisiana. In that area, rates of shoreline...
Crevasses on the Lower Course of the Mississippi River
Before construction of artificial levees, crevasses were a common event along the Mississippi River. They directed sediment out of the main channel and reduced flood stage down river....
Priority Problems of the Barataria-Terrebonne Estuarine Complex
The Barataria-Terrebonne Estuarine Complex encompasses an area of approximately 3600 square miles within the Mississippi deltaic plain, and consists of system of water bodies and wetlands...

Using GIS to Monitor Wetlands Loss/Gain
This paper represents the work being done at the National Wetlands Research Center (NWRC) for the U.S. Army Corps of Engineers (COE) to monitor wetland change in the Mississippi River...
Management of a Continental Shelf Ecosystem
The ecological system of the Mississippi-Alabama continental shelf is highly diverse and productive and contains unique natural features worth preserving. This system is intimately bound...
Consolidation Settlement Potential in South Louisiana
Primary consolidation is an important cause of wetland loss in active and recently abandoned deltaic plains in south Louisiana. Argillaceous and organic facies are most subject to reduction...
Salinity Variations in Two Louisiana Estuaries
Salinity variations, on a variety of time scales, are described for two shallow bar-built estuaries of the Louisiana coast. Tidal, sub-tidal, and seasonal scale variations are important...
Historical Shoreline Position Change for the Mainland Beach in Harrison County, Mississippi
Historical shoreline position change (1851/52 to 1986) associated with the mainland beach in Harrison County, Mississippi, are controlled by engineering activities associated with beach...
Mississippi-Alabama: Natural and Man-Made Shores?A Study in Contrasts
