re: Salt water wedge in the Mississippi River threatens drinking water in Louisiana

This issue about the salt water intrusion and coastal erosion are effects from forcing the Mississippi River to continue to flow through New Orleans.

An old man explained it best. Imagine a fire hose laying on the ground and is turned on. The end of the hose flops side to side. The Mississippi River used to do that and kept the coastal areas with sediment from the river.

When man forced the river in one direction and did not let it move slowly over time like it had been, we are not stuck with these side effects of that.
