Answer:

The US Army Corps of Engineers has begun rebuilding and improving the levee system that surrounds and protects New Orleans. A few changes include a new 26-foot-high wall that stretches for two miles near Lake Borgne, a place where flood water poured into the city. In the Ninth Ward, the corps has built another huge floodwall that is designed to protect against a storm of equal intensity to Katrina.  

These new floodwalls are taller and sturdier than in the past. For instance, the original floodwalls were I-walls, but the new floodwalls are T-walls, which are shaped as upside-down Ts to prevent the levees from sinking or failing. In addition, new floodgates have been built in a location where the Coast Guard had been forced to drop sandbags for days to try to stop the flooding from Katrina. Nevertheless, some people worry that the new system isn’t strong or comprehensive enough to prevent flooding after a Katrina-like storm. The new system is rated to last 100 years, but some people think a 500-year system is needed to fully protect New Orleans.

Explanation:

Hurricane Katrina is the name given to a very powerful storm in August 2005 that struck New Orleans by the World Meteorological Organization. This hurricane claimed the lives of many.

improvements in the levee system include:

  • additional construction rings that could reduce the impact of stormwater surges.
  • expansion of drainage systems, such as the construction of more floodgates, and increasing the number of pumping stations to about 24.

Although there are no guarantees this would provide complete protection from future storms, however, they are steps in the right direction.
