Few seem to doubt that this vital heart of U.S. commerce and culture will be restored, but exactly how to rebuild the
7、 city and its defenses to avoid a repeat catastrophe is an open question. Plans for improving its levees and restoring the barrier of wetlands around New Orleans have been on the table since 1998, but federal dollars needed to implement them never arrived. After the tragedy, thats bound to change, s
8、ays John Day, an ecologist at Louisiana State University (LSU) in Baton Rouge. And if there is an upside to the disaster, he says, its that now weve got a clean slate to start from.Many are looking for guidance to the Netherlands, a country that, just like bowl-shaped New Orleans, sits mostly below

Others, pointing to Venices long-standing adaptations, say its best to let water flow through the city, depositing sediment to offset geologic subsidencea model that would require a radical rethinking of archite

One is precisely how the current defenses failed. To answer that, LSU coastal scientists Paul Kemp and Hassan Mashriqui a
11、re picking their way through the destroyed city and surrounding region, reconstructing the size of water surges by measuring telltale marks left on the sides of buildings and highway structures. They are feeding these data into a simulation of the wind and water around New Orleans during its ordeal.
12、We cant say for sure until this job is done, says Day, but the emerging picture is exactly what weve predicted for years. Namely, several canalsincluding the MRGO, which was built to speed shipping in the 1960shave the combined effect of funneling surges from the Gulf of Mexico right to the citys ea

One of the first things well see done is the complete backfilling of the MRGO canal, predicts Day, which could take a couple of years.The levees, which have been provisionally repaired, will be shored up furth
14、er in the months to come, although their long-term fate is unclear. Better levees would probably have prevented most of the flooding in the city center. To provide further protection, a mobile dam system, much like a storm surge barrier in the Netherlands, could be used to close off the mouth of Lak
15、e Pontchartrain. But most experts agree that these are short-term fixes.The basic problem for New Orleans and the Louisiana coastline is that the entire Mississippi River delta is subsiding and eroding, plunging the city deeper below sea level and removing a thick cushion of wetlands that once buffe
16、red the coastline from wind and waves. Part of the subsidence is geologic and unavoidable, but the rest stems from the levees that have hemmed in the Mississippi all the way to its mouth for nearly a century to prevent floods and facilitate shipping. As a result, river sediment is no longer spread across the delta but dumped into the Gulf of Mexico. Without a constant stream of fresh sediment, the barrier islands and marshes are disappearing ra
