Problem 1. A water supply reservoir has an annual capacity of 40 × 10^3 acre-ft. It is serving a city with a present population of 85,000, which is expected to increase to 150,000 in 25 years. How many years from now will the city's needs exceed the reservoir's capacity? Assume arithmetic growth of the population and an average daily draft from the reservoir of 175 gallons per person. Disregard the losses.

) Gaziantep City has P2000=1,500,000, P2010=1,750,000 and (P.F.)day=1.6. The available maximum rate of water for GaziantepCity is 420,000 m3/day. Using the Turkish Bank of Provincy extrapolation:a) Find the year until when the available water would be sufficient to meet the demands of Gaziantep City during themaximum demand day.b) Find the capacity of the distribution reservoir in m3if it is designed for the sum of 45% of the average daily demand and afire discharge of 160 lt/s lasting 12 hours.
An 800-square-kilometer basin recorded 50 cm of rainfall in a year. During that year, ET was 5 meters, and recharge by ponds to the groundwater was 2.5e^7 cubic meters. Domestic pumping was 35 cubic meters/day and underflow from the basin was a loss of 25 cm. What is the total change in storage in this basin (give the answer in cubic meters per year)?

Q-5 Water is supplied to a city having a population of 1 lakh at a constant rate of 150 litres per capita per day. A graph is plotted between the cumulative flow versus time. From the curve it was found that the surplus is maximum at 7 hours when cumulative demand is 2.95 Million liters and demand is maximum at 20 hours when the cumulative demand is 13.65 Million liters. The maximum capacity of reservoir using mass curve method is ML.
