1 The average annual discharge at the outlet of a catchment with an area of 600 km² equals 11.42 m³/s. The average precipitation is 90 cm/year. a Compute the average evapotranspiration from the catchment in cm/year. b At the outlet of the catchment a dam is constructed. The area of the reservoir behind the dam is 100 km². The average open water evaporation is 70 cm/year. Compute the average annual discharge at the outlet after the construction of the reservoir.
