Unless rivers and bayous are allowed to overflow their banks annually to replenish silt deposits, the marsh will continue to biodegrade and subside like it has always done. Many do not understand that it is not a coastal erosion problem, it’s a problem of organic decay causing natural subsidence land loss, now with levees preventing flood silt replenishment.

Constantly that is true it is slow flowing river this makes it even more apparent. Those projects would need to be replaced every few decades.

Good short docu, but it raises one important question. The shrimpers and oystermen fear the saltwater species they harvest will be driven out by the reversal of coastline loss, which is necessary to keep their own homes from being destroyed ny hurricanes. But it's not like that's going to wipe out life in the area: OTHER species of seafood will move in. In fact, we've seen time and again that when we restore even a little bit of an ecosystem that existed for thousands of years before the last 100+ years of human alterations, biodiversity and fertility often goes up in unexpected ways, like the wolves of yellowstone cutting back the deer herds that overgrazed, leading to trees, leading to beaver dams, leading to a TON of new species of plants, fish, and animals returning to the park - it changed the rivers! So the oystermen need to ask the Native tribes still living in the area what seafood and hunting and other resources they LOST on when the Mississippi was diverted away and their freshwater wetlands went brackish. That had to be equally catastrophic, so there must be records or oral histories. Scientists csn probably dig up some of this history in the mud beds of the few bits of wetland that haven't been washed out to sea.

@barodrinksbeer7484

You coincidentally just explained why we should not support the reclamation of coastal land and the introduction of more freshwater species. We diverted the Mississippi river, it killed off a majority of the freshwater inhabitants of Louisiana in coastal adjacent areas. However, in no way did it divert the already existing encroachment of the coastal waterfront. Hurricanes would have brought invasive species to Louisiana and pulled non-invasive species out into the gulf stream (that's how biodiversity generally works in marine aquatic areas, especially for Halophilic life forms). Some aquariums have problems when they empty a tank from salt water to fresh (No matter what size tank), Halophilic bacteria generally tend to stick around and make it harder for more common bacteria to grow. Even with the reintroduction of freshwater, it will take years for fresh and brackish species to start inhabiting these waterways. By that time, the coastline will reincrouch upon these freshwater species, causing the same "problem" we had before. I like that you bring up Native tribes, because like native tribes we need to learn when to move inland when the weather is bad, then come back to fish during more favorable seasons. However, the reality is no one wants to do that.

The freshwater is actually good for the fishing industry. Shrimp and crabs actually move into brackish water to spawn. Freshwater also carries a lot of nutrients you can get in saltwater.

Can't have it both ways. Either get land there by the project or you don't. If you don't keep the ecosystem intact. It would be awesome to do both but unless you want to try to build an underwater facility to basically be a vacuum pump & have a hose to spread the sediment along the coast from further out in the gulf. Which would cost more, be more dangerous, cause more problems for the ecosystem, and probably not even remotely bring enough sediment to the coast as needed. I doubt you will find a better project.

This was great. Yeah, I remember when Katrina hit how they said that because of the lack of natural sediment, hurricanes are much more intense and a deeper coastal barrier would help slow the force of the storm. I haven't thought about it since and hope it works.

Malaria would be far more prevalent in the United States and shipping would be impossible in some areas

The Louisiana coastline has been sinking for decades as sediment from the mighty miss has deposited into the gulf hypoxia zone and depressed the sea floor. The same is going on along the western coast of Mississippi and that effect was exemplified during Katrina’s storm surge. The phrase “relative sea level rise” was born during hydrologic analysis of that hurricane’s tragic effects. Permanent evacuation of parts of the coastline is not popular but is a safe alternative when combined with ecosystem restoration and park development.

As to what happens- all those dying cypresses you see along I10 to BR are from salt water intrusion- long before the thirty plus foot levees were built, the Mississippi River Valley was covered with cypress trees- most of the older houses you do find in NO are built from that lumber. Randy, in so many ways man can never make that river basin or coastline what is once was. That was always a dynamic thing anyway- man threw in his changes and short circuited many long cycle natural ones. the decisions we need now are with an eye to what we will CREATE anew and what that would be, should be, what guide lines to use and what measures of success we might expect. but Randy- keep thinking, it never hurts and ma well help find the way to go. BTW, I've been that way down to the Inter Coastal Waterway- it was a great boat ride and a great time in my life. I've caught fresh salt water trout off Grand Isle beach and fileted them for breakfast. FR

We're doing similar here in the UK. We're breaking through our levies around the coastal farmland to create new wetland areas, which will help counteract both river and sea flooding!

Diverting water there would cause a lot of problems for communities upstream but it would be the fastest and most natural course of action for developing land vs keeping the Miss in its current state and dropping all the sediment into the massive oceanic valley right outside the current delta.

It starts with properly maintaining and dredging creeks, streams, basins and smaller rivers across the state. If they all were routinely dredged sediment could be strategically placed where it’s needed and minimize down river.

The sacrifices that this state made since the turn of the 20th century when the oil & gas industry began criss crossing the marsh with access canals for oil and gas operations has been a great sacrifice for so called progress. I worked in the oil & gas industry from 1971 to 2009. I worked right out of Venice and New Orleans and many different places all the way over to Corpus Christi. It was nothing for me to be in a helicopter or different sized boats every day. I have personally witnessed the changes that have occured in our wetlands here on a weekly basis and sometimes on a daily basis.

I was in New Orleans for the hurricane, and was in Grand Isle around 5 days later, the first day it was actually accessible by road. Never seen anything like it. The wind had blown over nearly every structure, and the water eroded the foundations out from underneath concrete pads. Power lines from distribution and transmission poles were strung along the ground.

So Kuwait is building these " one way" tide barriers that prevents water from rising past a certain point in their recent land development. It was done to help keep the water from becoming stagnate. So water can flow out but not flow in in certain areas to direct flow throughout the whole system.

No... Sea level rise has never been steady. During the little ice age in the 17th century the water level fell as glaciers grew. Current water level rise is much faster than in most historical periods because of the rapid warming over the last 50-100 years.

I'm 59 years old when I was a kid I used to ride horses on my aunt's property cross the street was a big plantation called The Fleming plantation and whole bunch of places down in Lafitte they are now under five feet of water the Mississippi used to flood and the receipt did it for thousands of years and it built the Delta the old companies in the engineers and whoever have dreads that River to where it doesn't do that anymore that's why we're losing land hurricane saltwater encroachment it's simple we can do something about it and I'm glad to see somebody's trying do something about it

Perhaps there is more than one way to accomplish what is needed. Off the coast of Normandy in France is a landmark island named Mont-Saint-Michel. Over time, sediment being washed in from the Atlantic and the English Channel was creating land that would eventually connect the island to the coast and ruin its charm. The local government addressed this by building a dam on the Couesnon River. This dam allows the tide water to flow in but only allows it to flow back out after the tide has receded for a while. This creates a fast outward flow that is steadily washing the sediment back to sea. Capturing sediment from the river in Louisiana is a very different challenge, but perhaps lessons from the success at Mont-Saint-Michel could lead to a design that harvests the needed sediment while allowing much of the fresh water to return to the river. A system like this might not impact the fishing waters as severely.

The first step should be a coastal barrier island system created by dredging. Dredge channels and stack the sediment, allow a berm to naturally form and let the sediment fill. Keep doing rows and rows inland then build a sediment diversion from the river system. Without flooding sediment diversion is useless, it will only take it to water level, a version of moving the submerged sediment above water level is going to be needed. Most of south Louisiana was built either when sea levels were much higher or by flooding caused by the end of the ice age. The brakes need to be applied to coastal erosion first and a barrier island system would also achieve this. It would also provide storm protection which is also greatly needed.

The lands changing everywhere rising and lowering; not just glazier melt is adding to changes in water levels everywhere. Its novel idea but getting on regrouping into mega structures with vegitation areas on roofs and such would be our best bet to grow with the changing position of the plates. The land could use a rest from us trampeling it.

Although apparently with the state experiencing fewer cold winter, the black mangrove has been expanding in the south part of the state. But the statement remains....just different vegetation that likes brackish water. When you channalize the river, less sediment and fresh water is added, and the flow reverses, the salinity raises, and kills a lot of the vegetation. Interestingly, as mangroves expand up the Florida coast with the increasingly warm climate, it pushes out oysters. They seem to not coexist.

What they need are a set of locks for ships to enter the river without letting water out, then just let the rest of the river overflow it's banks naturally and build the delta. This plan looks like only a partial fix as huge amounts of sediment will still go out the main channel.

Watching from Mamou, Louisiana.

Great work. Don’t get rid of your wetlands ever

So, determine the level of salt water you would need to pump in while you're pumping the freshwater and sediment. The water would remain brackish and would slowly build over time. Plant mangroves that thrive in those conditions and the land would be replenished. Right?

This not only impacts Barataria Bay it impacts the entire Mississippi Sound filling it with fresh water from the Mississippi River creating a huge dead zone in the summer from the coast of Louisiana across the Mississippi Gulf Coast to the Mobile Alabama Bay Area. Louisiana’s erosion problem will be come a Norther Gulf Coast problem from Barataria Bay Louisiana to Mobile Bay Alabama

So instead of fixing the issue at its source they choose to create a new issue. Thats government for ya. Removing the levees and returning the river to natural flow and flooding might just do a better job.

The only way to go or I-10 will eventually be a sea crossing. Not only does this land erode it settles and sinks.

The people that live off the land will still have to move and resettle most of them are older and cant just uproot. The land you want to create won't even be livable.

What about using some regenerative agriculture principles? Plant trees that drop leaves, that attract birds that poop. The bird poop fertilizes the trees & encourages more plant growth. The plants grow, drink the water, build the soil, drop their leaves, attract more wildlife, and so on, and so on, and so on. The Florida Keys did a sea grass restoration project, where they put perches over the water, where they wanted the sea grass to grow back. The birds landed on the perches, and hung out there, and pooped a lot. The bird poop fertilized the sea grass beds, and they came back. It was not very expensive.

They should be talking about building a lock system and moving all of the excess fresh water over to Texas, Oklahoma, and Kansas to deal with the drought problem. Take the dirt and fish out of the water first and reduce the amount of fresh water going into the coastal areas and everyone is happy.

I am rather surprised that SA had nothing to add about how much damage the "regulating" of the Mississippi's lower reaches has diverted all that silt to flow much farther out into the Gulf and not be swept westward by the inshore currents to be deposited as new land , just as it had for several hundred thousand years. Nor any comments on the damages brought from the many, many straight line canals dug by oil companies since the late '20s to make quicker transit to the oil zones from the coast. Several rivers that empty into the Gulf were also significantly straightened for the same reason, and that let's hurricane driven walls of seawater enter deep into those inland swamps and estuaries. Now, they would do the reverse- dump millions of gallons of freshwater into a body of brackish (or only somewhat salty water) which will have tremendous negative impact on fish and shrimp populations through the region. That Louisiana will pay for this with out demanding that the oil industry, that has so much blame due for it, will pay no premium to rebuild it. Somehow that seems just wrong, for the people of Louisiana, for the Gulf and for the US as a whole- once again an extractive resource industry gets a free ride at the consumers cost. FR

good ideas, sad situation. the river is almost dead at this point, and the sediments are contaminated with everything people did not want, clear up to montana. it remains to be seen if we are spreading the dead zone to other locations.
