There are concerns on how the new levees and flood gates
built after Hurricane Katrina in New Orleans may hold up in just five years according
to the U.S. Army Corps of Engineers.
The mammoth project to build levees, flood walls, gates and
pumps to protects New Orleans from another hurricane, finally finished up last
year at a cost of $14 billion USD.
While the threat of flooding is still very much a concern,
the Corps are conducting a study to determine if the system would even be worth
Within five years, all the new safeguards in place could
fail is a storm, similar to Katrina were to hit New Orleans.
Climate change is one of the driving factors that will cause
the system to fail.
In 2005, storm surge from Hurricane Katrina caused
catastrophic failure of the federally designed and built levees, flooding 80%
of the city. A report by the American Society of Civil Engineers says that
"had the levees and floodwalls not failed and had the pump stations
operated, nearly two-thirds of the deaths would not have occurred".
