A ground-water basin has a surface area of 125 km2. The following long-term annual averages have been measured:
Precipitation 60.3 cm
Evapotranspiration 46.3 cm Overland flow 3.4 cm
Baseflow 10.6 cm
is no streamflow into the basin and no groundA?1water flow either into or out of the basin.
(A) Prepare an annual water budget for the basin as a whole, listing inputs in one column and outputs in another. Make sure that the two columns balance as these are long-term values and we assume no change in the volume of water stored in the basin.
(B) Prepare an annual water budget for the streams.
(C) Prepare an annual water budget for the groundA 1water basin.
(D) What is the annual runoff from the basin expressed in centimeters?
(E) What is the annual runoff from the basin expressed as an average rate in cubic meters per second?
