combination of oil companies back in the day cutting up the marsh and then the adding of levees preventing the depositing of soil back in the marsh.



I really don't know much, at all, about this topic. Oil companies are responsible for Louisiana's eroding coastal lands?

Not the major contributor but the transition from land operations to offshore used what are called inland barge rigs. A great deal of canals were carved in the marshes to allow spotting those rigs on prospective sites. Some have been reclaimed by Mother Nature but the overwhelming majority helped contribute to coastal erosion. They also provided some damn good fishing spots so there's that.

ETA the intracoastal canal while great for most of the country also has contributed to LA coastal erosion.

The river doesnt carry enough sediment to counteract subsidence and it hasn't since the glaciers retreated from the continental US. south louisiana was always going to disappear we have just accelerated things a bit with groundwater extraction and digging channels. nothing really to be done.

erosion plays a v minor role in coastal land loss its all just literally sinking into the gulf.

True. They have functional government and a better education system than Louisiana.

Most of the sediment load at the south of the birdsfoot is going beyond the "shelf".

Want to fix it? Blow the dams upstream and let Old River go.

As long as they are there, you'll have a net negative of turbidity deposition to soil erosion.

Currently yes, but I had always read that the dams, weird, etc upstream trapped a lot of soil that previously had gone down stream.
