This is an interesting report commissioned by the United States Army’s London office. It assumes 2 feet of ocean rise over the next 100 years, and while it mentions subsidence, it does change its calculations based on subsidence in Louisiana. Since coastal subsidence may be a meter or more over the next 100 years, this [...]

Playing Politics with Morganza?
Took a drive up to the Old River Control Structure and the Morganza Spillway on the 12th of May. I was curious about what is keeping the Corps from opening the spillway until the flow hits 1.5 M CFS. One reason would be that until the river gets to that level, the water is not [...]
The Mississippi River and Tributaries Project
This is the Army Corps of Engineers explanation of the Mississippi River flood control system and how it would be used to control a flood. It details the the use of the floodways and the river flow levels that will trigger their use.[...]
Mississippi River Flood of 2011

Total volume of the flood is hard to compare because the river and the tributaries are more constrained than in the past. Water in a leveed river will be much higher than in a river without levees where it can spread out horizontally.

The Mississippi flood of 1927 resulted in the Flood Control Act of 1928 (FCA), the controlling legislation for flood control activities of the Army Corps of Engineers. The most important provision in the FCA is the blanket immunity for damages caused by flood control activities. FCA cases are collected here:
The Control of Nature – Morganza Spillway
John McPhee has written a fascinating history of the River Control Structure at Morganza. While it is not clear that the Mississippi still wants to go down the Atchafalaya, losing the River Control Structure in a flood would still be a catastrophe that could rival Katrina. “Three hundred miles up the Mississippi River from its mouth—many [...]
