t. Back water flooding of Bayou Bouef will cause damage east of Morgan City to the community of Amelia.
That’s why they sank the barge in Bayou Chene in 2011 and they’re considering doing again this year.
They’ve already approved the funding to build a gate there just a few months ago, they just haven’t started on it yet

All these predictions and concerns are assuming the COE is correct and built all that shite correctly.

There is a reason USACE created an organization that looks over the levee boards now. Because prior to katrina the individual levee boards were a huge reason the levees were so shitty.

Accident and the unexpected happen and the protection fails.

The Avoyelles Today has received news that a secondary man made levee (not the primary levee) has failed in Brouillette. Here is a post is from Ms.Judy Lachney,
Jessie Lachney's wife, I hate to be the one who has to give bad news but I must tell you people living in lower Brouillette and Spring Bayou that the levee in Adam Dupuy's field in lower Brouillette just broke and water is pouring in. This is from my son, Jonathan who is an engineer with DOTD. He and other officials just returned from there and he said it is pouring in. This means that within two days we will be seeing water. He said the only thing they can do now is get helicopters to drop large sand bags in the breach, hoping this will help.
We would also be helped if the river starts dropping SOON. The elevation at this point is 54 feet. This would mean that all low lying elevations will be flooding within a few days. Pray that the river starts dropping SOON. We need a miracle. Wanted you all to know this so you could be prepared. We have contacted the radio station and The Weekly News so they can announce this ASAP. We need to pray for a miracle because this could be very ugly.

can anyone link to a photo of this barge sinking strategy. I'm having a difficult time imagining how this works.

I’m saying exactly what I said.that levees in Nola we’re supposed to protect up to x feet (I think maybe 20’ of surge) and broke with less because they were built poorly by the coe.
All these scenarios assume they are correct and that all their stuff was built right and is good to go.
For all we know, they didn’t drive the morgan city levee supports deep enough (like the 17’ street canal in Nola) and they’ll all break at 15’.

Morgan City will disappear one day

Could the Atchafalaya basin handle the load if it were to become the new Mississippi?
The Mississippi river is 3-4 times larger than the Atchafalaya, roughly. If the whole flow of the larger river were allowed to go down the track of the Atchafalaya it would scour the landscape and completely remake the map. No town anywhere along the bank of the current Atchafalaya would survive. We are not talking flooding, we are talking scouring and moving earth and anything in the way of the river would be either silted over or eroded and carried out to sea. Pierre Part isa good distance away from the Atchafalaya channel, but its fate would depend on the meander that the new, larger river would take. If it meanders close to Pierre Part, it will be destroyed. At a minimum the event would certainly put it underwater either for the duration of the flood or possibly indefinitely depending on where the river settles. Every road from east to west would be ripped down by the river. Morgan City would not exist at all. The closest path to be able to get from West Louisiana to East Louisiana would be I-20 from Monroe to Jackson.

Thats Red River levee system?

Looking at the Atchafalaya River @ Morgan City, the record is only 10.5'. What are you talking about in your post? I am apparently looking at the wrong one.
Those are the projected issues if it gets to 12 or 20 feet.

quote:well...... Im not taking up for USACE but a lot went wrong with the failure of the protection system and would take too long to explain to you, what they think, really happened. So in the jest of it, i would not say it was poorly built. Under designed, maybe. Under maintained, absolutely. Poorly constructed.... I just dont see how this would be true as just like you and me, we want what we pay for. So they wouldnt have accepted a poorly constructed structure.

the levee supports? are you talking about the subgrade or are you talking about deep soil mixing?Posted on 5/23/19 at 5:01 pm to Duke

I'd bet it is more about storm surge protection than the river. Might not be on the gulf exactly, but isn't exactly high ground between them and the gulf and water pushing up the river wouldn't be ideal.
I'm pretty sure the FEMA flood design for Morgan City is overtopping of the Lake Palourde levees from storm surge, not the river.

They just spent a shite load of money on backwater flood protection around Morgan City since 2011. Morgan City is much better off than it was before. The levees and seawalls will protect MC up to something like 20’.
The problem is Lakeside and the Stevensville, Pierre Part, Bell River area due to the backwater flooding.
