Quoting News at IU: "Research from scientists at Indiana University and Louisiana State University reveals new information about the role humans have played in large-scale land loss in the Mississippi River Delta — crucial information in determining solutions to the crisis.
“What we found was really surprising,” said Doug Edmonds, the Malcolm and Sylvia Boyce Chair in the IU Bloomington College of Arts and Sciences’ Department of Earth and Atmospheric Sciences. “It is tempting to link the land loss crisis to dam building in the Mississippi River Basin — after all, dams have reduced the sediment in the Mississippi River substantially. But in the end, building levees and extracting subsurface resources have created more land loss and, according to our research, building dams has not had that big of an effect.”"
