Question

Using the inflows and outflows quantified below, draw a schematic water cycle for the catchment (size =125 km^2) and then calculate the water budget. The following long-term averages have been measured for the catchment (or watershed): precipitation : 60.6 cm, Overland flow: 3.4 cm, Evapotranspiration: 46.3 cm, and Baseflow: 10.6 cm. A. calculate annual water budget with inputs in 1 column and outputs in another. Columns should balance since you are using long-term averages. B. Prepare annual water budget for the streams. C. Prepare annual water budget for groundwater. D. what is the annual runoff (in cm) from the basin? E. what is the annual runoff from the basing expressed as an average rate in units of cubic meters per second?

Explanation / Answer

1) P=R+E+G

Water input water output

  60.6 60.3

2) stream flow

Evapotranspiration - precipitation =land flow + ground water flow

60.6- 46.3= 3.4+10.6

3. Ground water flow

60.6- 46.3-3.4

4) runoff= 3.4

5. 1.7 m3/s
