Factors Influencing Mottled Duck Nest Success On The Atchafalaya River Delta, Brendan Caillouet
Factors Influencing Mottled Duck Nest Success On The Atchafalaya River Delta, Brendan Caillouet
LSU Master's Theses
The Atchafalaya River Delta system along with the Wax Lake Outlet Delta and the Mississippi River Delta are the only three areas in Louisiana where land is being gained. Beneficial use of dredge spoil from shipping channel maintenance is used on the Atchafalaya River Delta to supplement natural accretion. These dredge spoil islands have the ability to provide valuable nesting habitat for a variety of waterbirds, including Mottled Ducks. Previous studies on these islands reported mammalian predation to be a significant cause of nest failure for Mottled Ducks. I tested the hypothesis that predator reduction through trapping would increase Mottled …
Long-Term Total Suspended Sediment Yield Of Coastal Louisiana Rivers With Spatiotemporal Analysis Of The Atchafalaya River Basin And Delta Complex, Timothy Rosen
LSU Master's Theses
The modern day Mississippi River Delta Plain and the Louisiana Chenier Plain have been greatly altered through anthropogenic changes to course and hydrological conditions of the Mississippi River and local rivers, most notably by levees that have excluded the Mississippi River from the delta plain. This has slowed accretion and increased land loss destroying vast quantities of marsh, endangering many coastal communities. This master’s thesis examined long-term total suspended sediment yield of four Chenier Plain rivers, total suspended sediment yield of the Mississippi River under different flow conditions, and total suspended sediment dynamics of the Atchafalaya River in relation to …
Water And Solute Transport In The Shallow Subsurface Of A Riverine Wetland Natural Levee, April Elea Newman
Water And Solute Transport In The Shallow Subsurface Of A Riverine Wetland Natural Levee, April Elea Newman
LSU Master's Theses
In riverine wetlands, the rate and magnitude of water exchanged between river channels and adjacent wetlands have a major influence on hydrologic function and associated aquatic habitat and water quality. River channels are generally separated from backswamps by natural levees; however, preferential flow may allow potentially substantial water and solute exchange between them. Determining the influence of preferential flow on water and solute transport in natural levees requires an innovative approach that allows measurement of transport rates at a scale large enough to capture field-scale variability. To test the hypothesis that preferential flow is important to subsurface water movement through …
