re: Mississippi River diverging: When do we finally let it go down the Atchafalaya?

The Petrochemical industry would never let that happen.

The amount of silt in the river now is 1/2 of what is was 100 years ago because of dams. But yes, if they blew the control structures, the MS would silt up and shallow because of low flow rate, wax lake would build substantially

The silt deposits on the seabed at the mouth of the (current) Mississippi, which is essentially a cliff into the abyss. It builds up underwater at the edge, and eventually collapses over the cliff in a huge underwater mudslide.
That area of the gulf is a mudslide zone to the O&G industry.

Is there any way to pipe the silts?I I know the corps did that in Florida to replace sand lost on beaches because of jetties. And since it's a finer particle size, it seems like it would be easier to do.Possibly pipe it through the dams, to reduce distance it would need to be piped?

If the Dutch can keep the North Sea out of Amsterdam than we can keep the Gulf of Mexico out of New Orleans and protect the wetlands too. The difference is the Dutch aren't abunch of limp dicks and aren't afraid to piss a few ppl off and implement their plan. Their national government also will address the issue. The USA not so much. What has it been 4 or 5 years since the coast2050 was passed and we can't secure a $1billion/yr for it. You would think that both sides would be jumping over saving the wetlands. Liberals would love it because it would (if the plan worked) save the wetlands and they would suck CO2 out of the atmosphere to combat GW/CC, and conservatives would love it because it show they care about the enivorment.

Long before Rising Tide there was John McPhee.
Atchafalaya
I've been to the control structures many times. It's been an on again, off again hobby of mine since my Daddy took me to see the Morganza Spillway the first time it was opened in 73. The ground was shaking. Never forgot it or the power of the River.

As sea level rises, so will Louisianas marshes, if there is ample sediment load. But there is not.

The Germans would methodically move the plants and New Orleans to the banks of the Atchafalaya and then let the River go.
The Japanese would find a clever way to redirect the River once it does change course with solar powered pumping stations.
The British would get drunk and dare it to move.
Only Americans would stand in the way and say to the Mississippi River, frick you. You go where we say.

problem is that beaches in Florida work under different dynamics. Longshore current is the major player there.
When you pipe in sediment, you will spend tons of money + you have to make sure the sediment actually stays. You can plant on the newly dumped sediment, but then it could create floating marshes, which really don't do anything for you

The Mississippi River will always have its own way; no engineering skill can persuade it to do otherwise...

I know, I know, but I do trust NASA. They do daily flights for twenty years measuring ice levels with a laser and see the ice melting. Notice I have not said it is man made issue but the data says the ice is melting and will cause sea level rise if it continues.

I am all for moving everyone south of bellchase and blowing the levees. The powers that be will never let the river reroute if they can help it. However moving everyone out of South plaq and blowing the levees is an actual possibility, and governor with a large set of balls is needed.

You got a link?
I've liked a lot of what I've seen from vice news.

That won't solve the problem. There is a thirteen foot drop between the two rivers at Old River. The ONLY thing standing between them is the Control Stucture(s). If that goes, it's over. Flooding Plaquemine will not help a bit.

Would help with sediment flying off the shelf

No doubt. It helps fix the wetlands problem. But the River would not be navigable for deep water vessels south of the City.
Look, and this is true. You can have New Orleans and the chemical corridor, or you can have the wetlands. You CANNOT have both. Period.

There's no way we could flood Plaquemines. I will fight like hell for those satsumas.
