Program Description

(This video is no longer available for streaming.) The city of New Orleans is cradled in swampland. To keep the water out, hundreds of miles of enormous levees and powerful pumps surround the city. But such a fortress is not invincible, and forecasters often have to make tough calls on pending storms. NOVA scienceNOW correspondent Peter Standring investigates what would happen if a hurricane hit New Orleans.
