Hurricane Katrina made landfall near New Orleans, Louisiana,
as a Category 4 hurricane on August 29, 2005. Despite being
only the third most powerful storm of the 2005 hurricane season,
Katrina was among the worst natural disasters in U.S. history.

In the wake of the storm, there were over 50 failures of the levees
and flood walls around New Orleans and its suburbs. The levee
and flood wall failures caused widespread flooding.
