re: IF the river were to change course...

The dykes were later repaired and the river resumed its original course.
That would not happen here, at least not if it went through at ORCS. There is a fourteen foot drop between the Mississippi River and the Atachafalaya. It might silt up some of that if it changed course through there, but it would still be untamable.

The water might come all the way to Lafayette if it busted through. I am told that in 27 it flooded all the way to the Coteau Ridge.

ORCS is 48 years old and there has already been one major scare in 1973. Who knows what this year will bring. That could be two major test in 48 years where the Corps almost lost the river.
There COULD be two? :omg:
The river isn't going anywhere. People love to imagine the worst.

As it was said on here a week or so ago, if that were to happen, I think the government and the oil cmopanies would spend billions to get it back diverted to its current course of flow.
And they could not do it either. You are going to have a fourteen foot waterfall flowing at an average rate of 500 kcfs. It will be flowing through marshy, unstable ground. There is no bedrock within feasible reach to ground anything on. If it goes, nobody, I mean nobody can put Humpty Dumpty back together again.

Under the current engineering, technology, and budget, every resource you can find says the exact opposite. I am not saying that it will happen this year, in fact it is highly, highly unlikely that it will happen this year. However, the Corps will tell you themselves how close they were to losing it in 1973. The fact that you do not believe it is going to happen one day does not change anything.

I'll grant you that this is a completely different monster. Someone asked if this ever happened to a major river in the modern era and the answer was yes. All they need to do is look at the Yellow River flood of 1938 to get an idea of how devastating this could be.
As far as I'm concerned, I'm expecting the worst.

Don't worry in 500-1k years it would change course again just as it had done before man began screwing with it. Hardly any of SE LA would even be here if the river had never changed courses.

i think they could IMO
it would be tough, but if we wanted to, we could do it
also, that 14' fall is basically our doing, if the river were free, it would level itself off eventually, not today, not tomorrow, but it would settle down

Have to update this. With the trend toward companies buying stadium naming rights, the Lafayette Saints new home will now be known as the TABASCOdome.

You don't have to fix it at the place where you can't fix it.
You fix it upriver at a place where you can fix it.

st doesn't matter, the world ends either in a few days or in 2012, so frick it all, we won't be here!

build a new structure and a new diversion channel
and then block the old one
its near impossible, but its not impossible
Posted on 5/13/11 at 8:57 am to LSUJuice

How?

How do you overcome gravity? The new river will be well below the bed of the old river.

And send it where? The east bank is far higher than the west bank. You would have to build a Panama Canal, complete with locks.

Sorry but i don't think it is possible to damn off the MS even if you had already dug the diversion. Too much depth/flow. It would take 200' sheet pile and enough filler to create a mountain. Not to mention trying to set this stuff while the MS is flowing.
Posted on 5/13/11 at 9:09 am to bayoudude
if you begin diverting more and more flow upstream, you can cut that down
it would be a monumental feat, but to say its not possible, i just simply don't believe
