Final answer:
The Hurricane Protection System (HPS) of New Orleans includes levees, floodwalls, and pumping systems. These structures are designed to protect the city from flooding caused by hurricanes and storm surges. The correct option is d.
Step-by-step explanation:
The Hurricane Protection System (HPS) of New Orleans includes levees, floodwalls, and pumping systems. These structures are designed to protect the city from flooding caused by hurricanes and storm surges. The levees act as barriers to prevent water from flowing into the city, while floodwalls provide additional protection in areas where the levees may not be sufficient. Pumping systems are used to remove excess water from the city during and after a hurricane.
For example, the city's levee system was designed to protect New Orleans from a Category 3 hurricane, but Hurricane Katrina was a Category 5 storm. The storm surge overwhelmed the levees, causing them to fail and leading to widespread flooding.
Hence, Option d is correct.
