I’m working on a environmental science question and need an explanation and answer to help me learn.500,000 people live in a specific geographic region, which generates an estimated 41.4 ft^3 of runoff per second.1) If the population uses 180 gallons of water per day, how much runoff supplies the annual domestic demands of the population?2) How much water is locally available per capita in this region? (m^3, person^-1, year^-1)?3) According to the Falkenmark index, does this region experience water stress?
