1. There are numerous methods for determining reservoir evaporation using various measurements. TIns problem assumes the water surface of the reservoir has an area of 10 6 m 2 (1 knl) with a steady flow rate of water into the reservoir of 0.2 m 3 S"I. (a) The steady flow rate leaving the reservoir is 0.15 m 3 S"I .
