re: There's too much dirt in the Mississippi River

Have you not seen or heard about all the restoration projects completed or underway?

yes, but there's still a butt load of money remaining.

That's not really true. Like any federal agency/dept, there are plenty of bureaucrats to slow things down and muck things up, but at the same time there are plenty of experienced and skilled engineers and administrators in higher positions there. Esp in the NO District.
They deserve blame from Katrina for towing a BS line to the public about the levees being safe, but they warned Congress over and over and over again that they needed the funding for better levee protection, flood control, coastal protection, etc. Instead of putting some money upfront, the American taxpayer had to blow literally hundreds of times that amount in dealing with the Katrina aftermath.

While I appreciate all the robust commentary in this thread, and I have learned a lot... I guess all this talk about coastal restoration and what to do with the dredge spoil, etc, is great, but my thoughts remain on a much simpler topic.
If 30 feet of silt have built up downriver of ORCS in a 20 year period... which essentially raises the level of the river, what is the quickest and easiest way to remove said silt, and to remove it on a regular basis so this never happens again?

The Corp is basically against someone paying for the extra pump/pipe to deposit to a different area then what the Corp has permits for. So the deposits get dredged to one location then you have to dredge from there to the location you want. When it would have been cheaper to just reroute the first dredges pipe.
You sir, are mistaken.
USACE NOD BUMP
then you call up the corp and try to get them to deposit it elsewhat are your dime........They wont. My Coastal guys do it all the time. Posted on 12/13/17 at 10:52 am to Captain Crackysack

The old bridge in br is too low for ships to pass under. Done purposefully by Huey long. No ships go past br
I am wrong. Old Bridge is 40' lower than Huey P.

Wrong...Clearance on the bridge in Baton Rouge is 113', clearance on the bridge in New Orleans is 153'

You better hope you're wrong, because they've spent a retarded amount of money around New Orleans since Katrina.
Don't put that remark on me. Mr LSU is the guy calling the Corps incompetent.
The USACE, like any bureacracy, has its share of inefficiency and red tape. What I don't believe is that it's staffed with people who are completely incompetent and/or corrupt. The Army sends a different bird colonel to New Orleans every few years to run the show in our area. Are we to believe every last one of them has been incompetent and/or corrupt? Sorry, I'm not buying it.

USACE and the CPRA are releasing for bid a sediment diversion/relocation project coming up soon.
They are just finishing up the PCCP pump stations project in NOLA and now all the funds are supposed to go towards this 2-3Billion dollar job. It’s going to be a design build but I think they are basically going to build massive canals to divert sediment where they want.
They aren’t as incompetent as pre-Katrina. That was quite the wake up call.

To remove the current shoaling?
Dredging, but it's neither quick, easy or inexpensive.
To maintain the channel?
Maybe we can try Dr. Xu's dynamite idea and sell tickets to mitigate the cost. But more likely, dredging.
If you can figure out a way to make the river drop it's sediment load at a particular place and in a consistent manner, you're going to be a rich man. In the meantime, the river will continue to be like the Honey Badger and do what it wants.

In Terrebonne Parish we have one piece of freshwater marsh still virtually intact. The area north of the Mauvais Bois ridge surrounding Lake Penchant to the Intracoastal Canal. Near the old Union Oil facility on the West end of the Mauvais Bois the canal is cut through the ridge. It used to be closed. Now Lake Penchant is becoming a tidal estuary. It could be closed in a day. The bureaucrats want the big fix. Not enough money and engineering involved to close the canal.

Hopper or cutterhead dredge
Takes a lot of time and mainly $.

Giant huge massive filtering systems every couple of hundred miles on the river?? Can't even imagine what that cost would look like.
So I think it's just a forever commitment to dredging. I'm sure it's not cheap... but it's gotta be cheaper than the MS River changing course.

I have several family members who are engineers who have worked in the past, or currently work for, USACE. Like you, I do not believe they are corrupt and or incompetent. However, they pretty much can't take a piss break without Congressional Authorization. And it's that Congressional Authorization that requires years and years of all the studies, environmental impact reports, etc etc. And then even if they get CA... no guarantee it will be funded properly, or at all.
They have designed and built, and continue to do so, some amazing feats. But if they are forced to use the lowest quality materials (because that's all congress will pay for) and they are forced to study the issue for years/decades (because Congress requires that) then I'm not sure what else can be done.
Not to mention... they are generally a building agency, not a maintenance/operating agency. All the billions of dollars worth of structures they built post-Katrina has been, or will be, turned over to local authorities. For a while, it appeared that the brand new permanent outflow canal pump stations were going to be operated by the NOLA Sewerage and Water Board. Do you have any faith they would properly maintain the pumps? Yet when they eventually failed, USACE would get the blame. Now the state is going to operate them... not sure if that's much better.
