Cr0w T. Trollbot asks: "It looks like New Orleans is going through something very close to the worst case scenario right now. This somewhat prescient study, written well before the hurricane, describes some of the challenges (engineering and otherwise) facing New Orleans. 'In this hypothetical storm scenario, it is estimated that it would take nine weeks to pump the water out of the city, and only then could assessments begin to determine what buildings were habitable or salvageable. Sewer, water, and the extensive forced drainage pumping systems would be damaged. National authorities would be scrambling to build tent cities to house the hundreds of thousands of refugees unable to return to their homes and without other relocation options.' The hypothetical is looking awful close to reality right now. What can be done about draining and rebuilding New Orleans in light of the massive flooding, and what can be done to prevent and/or lessen such disasters in the future?"
