Blow the levees south of Belle Chase but levee the communities themselves ie Port Sulphur and Venice. Connect them with a causeway for transportation.
Then over the next 10yrs move the port of New Orleans along lake pontchartrain in New Orleans East. Moving the port actually makes more sense economically as its a more direct shot to the gulf from the Lake via Chef, Lake Borgne, and Miss. Sound.
That's all I got...

I like how you just assume they know what they are doing because they are dutch.

do you have numbers on that metric tonnage of silt today versus "back then"?
In 1850 there was 11 billionty shittons of silt; today there is less.

Im so confused by humans classifying scientific and geological events as "sad". Some volcano erupts, "how tragic, look at all the destruction." Louisiana erodes "how sad, what a loss." The surface of the Earth is everchanging. There is no boot shaped place where we call Louisiana. We drew lines and made it a boot. How tragic it must have been when Pangaea broke apart...

watch the build it bigger episode on the port of rotterdam and floating city, then do some research and get back to me

Forgive my ignorance but can you explain why blowing the levees will reverse the erosion. Is it bc of all the sediment that will flow into eroded areas and eventually build itself back up?
No one is seriously talking about just blowing up the levees, let's get that out there first and foremost.
The problem is that the Louisiana coast has been built mainly by sediment dumping from the Mississippi River as it flows out through the marshes. The levee system has corralled that recharge and sent it straight out to the Gulf so the coastline is not only not getting new sediment to expand with, it's not getting enough to replace what's already there when it erodes out.
On top of that, there's also the issue with salt-water intrusion from the Gulf that kills fresh water habitats. Without the levee systems in place, these marshes would have been recharged and the salt either pushed back out or buried, thus rejuvenating the fresh-water habitat once again. With the levee system in place the habitats have to depend on normal rainfall and human intervention, neither of which are nearly as effective.

Do you have to remove all the levees or could you just cut strategic holes and dig channels to areas that you want to rebuild?
I think what needs to happen is a drastic re-thinking of the levee system from Alexandria southward. Instead of walling up the river, the better option might be to wall up the towns and have more raised roadways. This would be very expensive, but not nearly as expensive as losing almost everything below I-10 over the course of the next 100 or so years.

Just pump the sediment that is currently dredged and dumped off the continental shelf in to the wetlands and watch them flourish. The grass will take over, it's grass in south LA for goodness sake it will grow.
They have to dredge the Mississippi river passes constantly to allow ships to pass and waste that sediment all day every day. Let's start here, it isn't rocket science.

and rebuild the barrier islands to slow down the errosion of current wetlands and help protect from hurricanes

But it isnt water.
good god. subsidence is an issue, but this is just bullshite.

doesnt work like that due to particle settling size in the physical environment.

People were making this argument back in the 80's fwiw.

f this was done in the NOLA area it would totally change the saltwater fishers in the area. Thus the push back from commercial and residential fishermen will be hugh.
It's unbelievable how much of this discussion is dominated by guys who don't want to spend an extra $20 on gas to find specks.

I love the responses these guys are giving..... It is "so simple". First this dredging of the mississippi, do you know how much money it takes to move this to other locations? I do and it is not pretty.
Second, where are you going to put it, and who decides where. What if the best place isnt owned by the state? Or you cant get the area permitted for this type of construction.

where did i say that? 2nd if you want it done soon they might be one of the only government entities that could push something of this scale through local, state, and federal government. This post was edited on 9/9/14 at 2:39 pm

a couple of years ago we bought into a hunting club on the unproctected side of the ms river and in one of the papers there is a clause that the COE can do whatever they want with that land as long as they compensate us, so I am sure it is that way up and down the river.
As far as the money goes the La costal masterplan in 2012 cost a billion dollars a year. Our fed govment flushes more than that down the toilet each year
