Sitting between Lake Pontchartrain and the Mississippi River near the Gulf Mexico, New Orleans was once a thriving U.S. city, famous for its Mardi Grascelebrations and talented jazz artists. Before Hurricane Katrina flooded the city in2005, almost half a million people had enjoyed the city’s relaxing culture.     New Orleans rests in a bowl about two meters below sea level, and it isprotected from the water around it by a system of levees, which dates back to the1960s. These levees, or water barriers, circle the entire city and prevent the watersof Lake Pontchartrain and the Mississippi River from rushing into the city. Somelevees are made of concrete, but many are made of earth, reaching 210 kilometersaround the city. Within these levees are pumping stations and canals to keep the landdry, even after heavy rainfall.      In 2005, Hurricane Katrina hit New Orleans at full force. Katrina’s highwinds and storm surge destroyed some levees. As a result , more than 80 percent ofthe city was left completely underwater, killing more than 1500 people and leavinghundreds of thousands of people homeless and thousands without food, fresh water orelectricity. To make things worse, the major roads going in and out of the city wereeither destroyed or under water, making it very difficult for survivors to leave the cityor for aid workers to enter the city     To help these people and their city, the federal and local government have spenthundred billion dollars cleaning up the mess, building better levees and rebuildingdamaged homes and businesses. The extent of the damage, however, was so severethat some experts estimated that it would take more than ten years for the city torecover and for all its former population to return.
