Pre-flood ORCS is designed to keep 70% of Mississippi River flow in the Mississippi, with the other 30% going to the Atchafalaya. The flood structures are designed to keep anything above the 70% ratio out of the Miss and divert it to the Atcha.
But if the Atcha captures the flow (say, flip the percentages to 70% Atcha and 30% Miss), there may not be enough water flow in the Miss to sustain shipping traffic, seriously disrupting the economies of both BR and NOLA.

Without access to the ports along the river the nation would suffer a major economic blow
People need to understand....the mouth of the Atchafalya River can only handle a ship with no more than a 15' draft.....thats not very much

That's until the ole miss starts roaring down its mouth.

Morganza hasn't gotten this much attention since Monte Burke's glory days.

The Mississippi would make a channel, but there would indeed be SERIOUS disruptions in trade while infrastructure was moved and the new course was worked on to make it as passable as the current course.

there will be no infrastructure to accommodate trade......you are all missing the point.....if there was then dont you think the Corps would have been dredging all these years at the mouth of the ATCH River to allow bigger boats????

Do you realize how long this would take??

quote:No, not really. This isn't about diverted flow. This is allowing a wide area of water to pass though gates in what is, in effect, a levee very far from the source of the water. It's in some ways similar to BC, but in other ways different. It is nothing like ORCS at all.

I don't know enough about it. i don't think the river will change course. But where water is flowing generally forms a channel and I thought they were worried about it undermining the system(to me that means eroding away sediment thus leaving the structure obsolete)

I thought we were discussing failure of the Morganza spillway structure, not the old river structures? Mass confusion... swapping back and forth between two totally different scenarios.

Infrastructure will move from New Orleans and BR to whatever the new port would be. The only current more relentless than the Mississippi is that of Commerce. It would indeed take a while and there would be large upheavals in the economy for the middle section of the country (the East and West coasts wouldn't feel nearly the effect Ohio would, for example), but humans are pretty good at adapting.

Why would they want to do that when their money and effort has been focused on NOT allowing the river to change course?

the severe impact of the loss of the Mississippi on New Orleans, a city in no desperate need of another disaster: With its fresh water gone, its harbor a silt bar, its economy disconnected from inland commerce, New Orleans would turn into New Gomorrah. So significant did the Army Corps of Engineers view the threat of such a course change to be, it produced an information video that bore the following message: This nation has a large and powerful adversary. Our opponent could cause the United States to lose nearly all her seaborne commerce, to lose her standing as first among trading nations. . .

This thread is not about the river changing course. It's about people thinking that it could possibly do so at Morganza instead of at ORCS.

Also, several tons aint shite against a couple million cubic feet per minute of water
They wouldnt even try to close the gates until the water has receeded. Once open they stay open.
The river will not jump at Morganza. There is no channel. It will jump either at ORCS or just to the north of it where the Red and Mississippi are only about 3 miles apart.

Where? Morgan City would be a sand bar.

You dont get it....MC could be a huge port for the the bigger boats to service the Oilfield and large cargo ships to service overseas trade...the corps wont spend the money

I know about how the water diversion at old river works. And judging from your reading comprehension skills, I may understand it way more than you.
MORGANZA SPILLWAY IS WHAT IM TALKING ABOUT. THE RIVER WILL NOT CHANGE COURSE HERE. AT THE MORGANZA SPILLWAY. MORGANZA SPILLWAY, IT WILL NOT HAPPEN HERE. NOT AT MORGANZA. If morganza fell down in the raging waters, it still will not change the rivers course here.
