Those programs would seek to: ► Protect drinking water, wildlife and river-dependent industries by reducing runoff pollution. ► Reduce flood and storm risks and increase community resilience. ► Protect and restore wildlife habitat, in part by preventing the spread of aquatic invasive species.
How is the Mississippi river changing?
The Mississippi River has changed course to the Gulf every thousand years or so for about the last 10,000 years. Gravity finds a shorter, steeper path to the Gulf when sediments deposited by the river make the old path higher and flatter. It’s ready to change course again. Gravity makes water flow downhill.

A popular kind of revetment on the Mississippi is basically a massive “concrete mat.”. In the video above, you can see one being built.
Why does the Mississippi River move so slowly?
As rivers move from higher elevations to lower ones, the amount of energy contained in the water goes down. All the stuff the water had been carrying along in swifter waters starts to fall to the bottom of the river as sediment. In the lower portion of the Mississippi, the river moves very slowly.
What did the French do to the Mississippi River?
