The View Today

Hurricane Katrina exploited and forever altered the landscape of Louisiana. As reconstruction gets underway in New Orleans, scientists are looking at the underlying foundation of the levees and the surrounding wetlands for answers to what went wrong, and ways to guard against future storms.

A Checkered Past

For decades, New Orleanians placed their trust in a storm defense system that, 40 years since its construction, was still not completed when Hurricane Katrina swept in. A look at the history of the levees reveals misplaced priorities and outdated science that left the city's back door vulnerable to massive flooding.

Future Outlook

To guard against future hurricanes, engineers will have to rethink New Orleans' flawed protection system. Scientists are looking not just at man-made defenses, but also, to restoring Louisiana's wetlands as natural storm barriers.

Rebuilding Levees, Rebuilding Neighborhoods

It's been a year since Hurricane Katrina drowned New Orleans. Now returning residents wonder if the levees that failed in that storm will protect them. Living on Earth reports on the levee repairs.
