Swamp Thing: Lawsuit Blaming Oil Companies For Wetland Loss Might As Well Blame The Plaintiffs
The multibillion-dollar lawsuit that Louisiana plaintiff lawyers launched against the oil industry last week is based upon a compelling theory: In their century-long quest for oil and gas, drillers helped destroy the state's protective wetlands by digging a network of canals that introduced "corrosive salt water" into the delicate ecosystem.

I also think that half of the problem currently was the diversion of the bulk of sedimentation into the "Birdfoot delta" via the USA corps of engineers. The result is that a significant area of sedimentation now exists on the extreme E. part of the delta (good for prevention of direct hurricane surge flooding on the SE quadrant of new Orleans, but Very bad for the N. quadrant of the city where the surge gets funnelled into lake Pontchartrain.
The direct dredge channel maintained sedimentation in the birdfoot delta starves the rest of the delta of sediment and it continues to subside with time.
The best solution now is to avulse the delta into the old Atchafalaya channel W. of New Orleans,(which was about to avulse before the corps of engineers shored up the old logjam) and to maintain the "birdfoot delta" as a ship canal with an overspill for sedimentation & dredgers directly through the flood wards into Pontchartrain.
The result will be a new sediment pulse into the W. part of the delta (currently shallow sea & disappearing saltmarsh), with sediment supplied by longshore drift & storms onto saltmarsh fronts on the main delta. The old birdfoot delta will shrink and move becoming a new set of chandeleur type delta foreset dune islands with the ship canal behind them; (storm sediment movement will strictly limit ship canals through the sand dune front).
Have a nice day: Ag
