Question

A 4000-square kilometer watershed receives 102 cm of precipitation annually. The average flow of the river draining the watershed is 32.4 m3/s. Infiltration is estimated to be 5.5 x 10-7 cm/s and evapotranspiration is estimated to be 40 cm/year. (a) Determine the annual change in storage in the watershed in m3. (b) Compute the runoff coefficient, C (runoff/precipitation) for the watershed.
