Extracted text: 1. The New York City water supply system is one of the most extensive municipal water systems in the world. This complex system relies on a combination of tunnels, aqueducts and reservoirs to meet the daily needs of millions of residents of the city. The watersheds that feed into NYC reservoirs have a total surface area of 1,969 mi², and receive an average annual rainfall of 47 inches per year. a. If all of the rain falling on the watersheds is collected in reservoirs, how much water will be collected in the reservoirs? 4.4 billion gallons per day b. Would you expect all of the rain falling on the watersheds to reach the reservoirs? Briefly explain. Yes because all of the water at some point will end up running off into the reservoir whether its from the ground or run off from a hill or incline, c. If 35% of the rain falling on the watersheds is collected in reservoirs (i.e., the surface runoff coefficient = 0.35), how much water will be collected in the reservoirs? 1.54 billion gallons per day d. If we experienced a prolonged period of drought with an annual rainfall of 22 inches per year, (For this part, again consider that 35% of the rain falling on the watersheds is collected in reservoirs.) billion gallons per day Check e. Would there be enough water falling on the watershed to meet the current water demand of NYC of 1.1 billion gallons per day under our average rainfall (part c) and under a prolonged drought (part d)? Briefly explain.
