Throughout the world, sea levels are rising, coastlines are crumbling, and the intensity of hurricanes is increasing. Is the situation in New Orleans a glimpse into the future of all cities that exist near major bodies of water? Filmed six months after Katrina, this program analyzes why New Orleans flooded so catastrophically and asks whether the city—constructed on a steadily subsiding floodplain and losing coastal barrier land at the highest rate in the U.S.—should be rebuilt at all. Louisiana State Climatologist Barry Keim; Harry Roberts, director of LSU’s Coastal Studies Institute; hurricane expert Ivor Van Heerden; Colonel Richard Wagenaar, of the Army Corps of Engineers; and Hassan Mashriqui, who is developing coastal hydrologic/hydraulic modeling capabilities for the LSU Hurricane Center, are among the experts featured.
