Delaune, R. D., and Jugsujinda, A. "Denitrification potential in a Louisiana Wetland Recieving Diverted Mississippi River Water." Chemistry and Ecology. 19.6 (2003): 411-418.

This article diverts Mississippi water through part of the Louisiana wetlands and measures the levels of Nitrogen and other compounds in the water. They propose that this method will lower levels of Nitrogen in the Gulf of Mexico and increase oxygen levels.

Biever, Celeste. "Why Splitting the Mississippi won't Save the Wetlands." New Scientist. 191 (2006): 10-11.

This article discusses the effectiveness of splitting the Mississippi in restoring the Louisiana Wetlands. They argue that it will not help because the wetlands already have the kinds of sediment that the river provides, but is lacking the kind of sediment provided by decaying organic matter.
