National Geographic has published an article on the New Orleans levee system entitled "New Orleans Levees, Are They Safe?". The article indicates, as has been reported from other sources, that the levees are now back to where they were Pre-Katrina, but is that really good enough? A group funded by the NSF with members including UMR Professor J. David Rogers and Berkley professor Bob Bea has pointed out various shortcomings of the levee system. The Corps has responded with the view that the levee system is adequate, and that new flood gates will prevent a storm surge like Katrina’s from overtopping the existing levee system.
