Has anyone mentioned the positive effects of knocking down the berms the CoE have established along the mississippi river up to Baton Rouge? Thats the only way to save the marshes.

sand berms that can be torn down if need be?
You do not need to tear them down. One small storm will do that naturally. This is indeed a complicated subject that doesn't have an obvious answer. The easy stuff gets screwed up do to lack of knowledge by the public and the media as compared to those making the decisions. So tackling a complex subject like this is 1000 times tougher.

That is a whole different pet peeve of mine. Think about that issue like this.
You own some land along the lower Mississippi River. It has no levee. It needs the annual floods to keep it from subsiding beneath the water. The Corps of Idiots comes in and builds a levee and you land slowly starts washing away.
No the problem with the levees is discovered. So someone other than the corps has to come up with money out of their own pocket (you/or state funds/or restoration funds) to break the levee in a few place to slow down how fast you are losing your land... CAUSED by the COE.
Now that that is done to put the river slightly closer back to it original state the frick COE demands that you use restoration funds to dredge the river because it is silting up faster than it was when the levee was there.
HELLOOOO, frick you. You do not have the right to screw over me and demand that I pay to have my river back. YOU (COE) stole from me and you demand that I pay to have what is rightfully mine back!!!! bullshite.
Another analogy of sorts is when the government takes your land to build a hwy they have to pay you for it. Here the COE is destroying your land by interrupting natural processes and then demanding that if you want your own river back you have to pay them!!! arse backwards!

Omega, you appear to be putting much of the blame on wetland loss on the leveeing of the Miss River by COE. Its a dual threat from COE and Oil and Gas.
Most peer reviewed scientific journals place it 60-40 or even hire on oil companies.
GIS data says 11% of land loss alone is due to carving canals and channels alone. Leveeing the Mississippi River did not cause channels to be dug. Look at some aerial photographs of wetlands and see how many straight cut through expansive marshes there are.
Another big factor which contributes 25-36% of landloss rates is when they dug the channels they piled the sediment on the bank esssentially creating levees and blocking water flow. The land behind the spoil banks compacted naturally and sunk and forming shallow water areas. This practice has changed but it was done by oil companies (70's and 80's)none the less.
Another 2-5% can be accounted for that the land sits on pillows of oil. The rigs acts like a giant mosquito and sucks the oil out causing the land above to sink and fill the void. Much of Terrbonne basin landloss is due to this.
All these numbers can be supported by peer reviewed scientific papers.
Levees on the Mississippi is also a large factor too and no denying that. But many assume the oil industry has no impact and that is simply not true.
I believe the Gulf Coast Restoration Act will have monies from all oil companies and a small percentage tax from each barrel of oil. This should help with restoration efforts. However, the govt seems reluctant to spend money regarding restoration. If we had a shot to get money, we just lost it with dredging valuable habitats to build very short term berms.

I was just commenting on the question of the levees in response to the question.
I am well read on the subject of coast erosion. There are a number of factors, without a doubt.
