Many studies say capturing Mississippi River sand through diversions is key to rebuilding Louisiana's vanishing coast. But a new study of an old levee breach along Bayou Lafourche, La., indicates that mud, the most plentiful sediment type carried by the river, may be the most powerful tool in building land. The researchers found that mud can build enough land to keep up with sea level rise if the diversion flows into existing vegetated areas protected from marine forces.

Climate change-caused flooding threatens Texas


The East Texas coast could face chronic flooding by the end of the century, or even earlier, if worst-case carbon emission scenarios come to pass, according to a report by the Union of Concerned Scientists. The report concludes that even under optimistic estimates, nearly a third of the Bolivar Peninsula will face serious flooding about every other week by 2060, and more than half the peninsula will face chronic flooding by 2100.
