In a given year, a catchment with an area of 2500 km2 received 130 cm of precipitation. The average rate of flow measured in a gauge at the outlet of the watershed was 30 m3/sec. a.) How much runoff reached the river for the year (in m)? b.) Estimate the water losses due to the combined effects of evaporation, transpiration, and infiltration due to ground water (in m), assumed that no change in storage within a year c.) What is the runoff coefficient?
