I testified about flooding on the Mississippi before the Mississippi River Commission in Greenville on April 18, 2018. Readers with properties on the river, its oxbow lakes, and tributaries may be surprised to learn why they flood. It’s the bottlenecks.
I think everyone here knows the Mississippi is flooding more. But you might be surprised to know that it’s the worst in 400 years. And that most of it is due to flood control projects. That’s right, flood control causes flooding. According to research published in Nature this month.
The engineering answer is simple. The politics aren’t. Here’s the story.
There is a flood arms race. It could end in disaster. It’s between the US Army Corps of Engineers and the Mississippi River.
What would happen if the Mississippi River changed its coarse to the Atchafalaya? Dr. Xu’s poster gives an in-depth look at the MS River’s history, likelihood of a coarse change and the consequences.
Have flood control projects actually made flooding worse? Yes. Floods are higher, longer, and more frequent than ever. Despite the Corps’ Mississippi Rivers and Tributaries Project authorized in 1928. Which the Corps says has prevented a trillion dollars of flood damage from levee failures that haven’t happened.
