The Corps has a robust program to clear navigation channels to ease traffic, dredging 78 million cubic yards of sediment and other material annually and using about 38% of dredged sediment for the purpose of restoring wetlands. By pumping this sediment into wetlands, they have constructed approximately 68 square miles of land through this program to date.
Interesting article about the Mississippi River and coastal restoration in South Louisiana. I wish more of the sediment from the Mississippi River was being used to create land than the 38%. I know it's expensive but how about barging it to where it's needed? And I wonder how much of the 68 square miles of land that has been created is still there, compared to the amount that has washed away. Fresh water diversions would replenish the loss that is always happening. Sediment diversions from the Mississippi River are the answer, let's hope for more of them.
