Wind-driven expansion of marsh ponds on the Mississippi River Delta is a significant factor in the loss of crucial land in the Delta region. A new study found that 17 percent of land loss in the area resulted from pond expansion, much of it caused by waves that eroded away the edges of the pond. The findings add to scientists' understanding of the processes that shape the Delta and present new challenges for scientists and engineers seeking ways to protect sensitive coastlines.
