Do you have the numbers to support this? I find it hard to believe that more goods are shipped through the Port of New Orleans than were shipped 30-40 years ago.

Google "the meandering Mississippi". A beautiful map with all previous paths of the Mississippi. Great art/converaational piece.

I find it hard to believe that someone thinks the river was busier in the 70s than it is today

I’d have a front row seat for the natural upheaval. I’d drag a lawn chair and a cooler down to the levee. Maybe a hibachi and make a day of it.
Edit: Ignoring the disastrous economic consequences for NOLA, this would result in a rare semi-natural scene in the riverbed, where the greatly decreased river flow meets a saltwater body that rises and falls with the tides up and down the channel. I call it semi-natural because of the levees.
Might happen a little upstream of NOLA.
And plant life along the batture would be drastically altered. There’s a lot of St. Aug and other grasses there now that wouldn’t make it. In the interim what’s controlling erosion?

That's an interesting article. I didn't know so much gasoline was shipped through the port of New Orleans.

The definitive story on this is “Atchafalaya” from the book The Control of Nature” by John McPhee published in 1989. It describes it all in geologic, historic and contemporary human terms. It may well be that the course change is inevitable.

There's no way to effectively combat coastal erosion without redirecting some of the current course of the river.

It’s not going to happen in our lifetime. These stories come out every year to let Louisiana mooch for more money to waste on food stamps
It came close twice in the last 45 years. Not happening in our lifetime is a pretty bold prediction.

If that happens, the gulf seawater will come upstream past Nola. I would think Nola port would still have deep water access
The problem for New Orleans is that the saltwater wedge would go past Kenner, meaning the entire New Orleans area would lose its source of fresh water. The entire water system would be destroyed and expensive desalinization plants would have to be installed IMMEDIATELY

Saying it "came close" is pretty disingenuous. It didn't come close in 2011.

Are there any experts who post here who can weigh in on this possibility?
No less than half the posters here

I say we let it change

Take a look at this map of the movements of the Yellow River in China and then notice the longitude and latitude lines to show just how much movement is possible across flat coastal lands.

2/3 of the US drains into the Mississippi River. It would disrupt international trade bigly.

Maybe temporarily. I doubt having to drive a boat 70 miles west is going to be too big of a deal

Well, that is the natural course of events.
We are performing the unnatural act by keeping it flowing on its current course.
