re: Mississippi River could change its course forever during one major flood

Yes. That and with all the diversions planned along the MS river, they'll do whatever possible to keep its current course

I think it would be a short term change of course. Corps of engineers would bring barges of limestone rocks just south of old river CS and blow up to sink in low water /flow like August to force the river back to current path. Too much financial impact to let it go down Atchafalaya.

Are you obtuse? You realize they locate on the water for a multitude of reasons. Cooling water, deliveries and shipments...

I've said it 100 times, the MS will shift to the Atchafalaya AT some point. Nothing we can do about it
Might be 5, 50, or 500 years but it WILL happen
I look forward to our government trying to force it to its current course for decades/centuries to come until the last moment when it shifts and being completely unprepared when they could've instead spent this time/money preparing for the shift

New Orleans would lose its status as a major port and would effectively die a quick economic death overnight.
And, given the effort it would take to make the new channel navigable, it's plausible that some kind of canal of channel would be constructed that still made New Orleans a central fixture in that trade.

It's hard to imagine, just as all disasters are.

New Orleans and Morgan City fricked
Houma stacked.

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
Costly, but at least their drinking water would be worth a shite.

Remember the 1973 flood? We thought Big Muddy was going to take out Morgan City when the ORCS failed.

Freshwater aqueduct from the Northshore would probably be more feasible.

YES, would still have deep water access. However, the problem is then it wouldn't have inland access via waterway. Although truck and rail distribution can sustain a port NOLA became a thing because of its inland access to 2/3 of the US via waterway.

Can you imagine the major flooding across southeast Louisiana if there's a failure on the eastern levee during a major flood? Or if it gets so high that the ORCS fails and they have to start blowing the levees to save some areas? We just thought August 2016 was terrible. There'd be backwater flooding on a size and scale the country has never seen before. Every river, canal, and bayou around would rise above its banks ten fold and water upstream wouldn't have anywhere to go for hundreds of miles.

It nearly happened after very heavy rains in Louisiana met up with Mississippi river flioding.
Yes it can still happen.
Yes we know that the expense
Would crush Louisiana and usa economy.

How would it affect Baton Rouge?

Considering the scenario would present an unprecedented event, I have no idea. I'd imagine it would be horrific, though.

I doubt anyone knows specifically to what mile marker the salt water wedge would intrude, and it would be more rational, quicker and cheaper to build pipes say 20 miles up river to obtain fresh water than abandon our existing water system.
I think the real problem is where along the current path of the bottom of the Miss River crosses the 0' elevation marker. According to some rough numbers, that place lies between BR and NOLA.
Assuming the stretch between NOLA and BR gets silted up, theres a real possibility the river dries up completely north of where the 0' elevation meets the current bottom of the river.

Northshore wouldn't allow it. It has been tried before.

Traffic is more easily fixed because there is no traffic. In this scenario, I-10 over the Atchafalaya basin and 190 are both washed out.
Has the BR loop been built by time the MS River changes course?
