What are levees? Do they protect the city?

Levees are artificial embankments or walls designed to prevent a river or other body of water from flooding adjacent land. They are built parallel to the waterway and can be made of earth, concrete, or other materials.

Levees are designed to protect the city from flooding by containing the water within the river or lake. However, they are not always effective, especially during severe storms or hurricanes. If the water level rises too high, the levees can be overtopped or breached, leading to catastrophic flooding.
