There’s widespread agreement that puncturing levees and diverting sediment-rich Mississippi River water into adjacent wetlands is key to saving the southeast Louisiana coast. […]
Understanding the overall demands on the river is critical to the master plan because the river must also serve other important needs. […]
The goal of the research, he said, was to see if the conventional scientific wisdom about how much sediment the river carries in its upstream reaches holds true on its last leg to the Gulf. […]
While the study of river hydrodynamics was first proposed in 2004, it wasn’t funded until 2011. So the scientists working on the 2012 edition of the master plan put together preliminary planning models that prepared the way for the more-detailed operating models to be developed when the latest data on the lower river became available. That work was cheered in peer reviews, even though it was based on river data that, in some cases, were decades old, researchers said. […]
Planned since 2004, the study lately has taken on new urgency, as a result of evolving insights into the river’s capacity. […]
If there’s one underlying assumption that’s been used to justify the $50 billion cost of Louisiana’s Coastal Master Plan, it’s this: We actually have a chance to prevent Southeast Louisiana from drowning in the Gulf because the Mississippi River carries the mud and sand necessary to keep pace with sea-level rise. […]
Stunning new data not yet publicly released shows Louisiana losing its battle with rising seas much more quickly than even the most pessimistic studies have predicted to date. […]
