Q2
The average annual rainfall is 800 mm/yr in a catchment of 100 km2. In its original condition
the average annual total runoff is L.1 m/s. In an average year, 50% of the rainfall infiltrates
and 12.5% of the rainfall reaches groundwater. Tests have shown that the average annual
evapotranspiration from the unsaturated zone is 340 mm/yr. Assume water balance over long
time period, compute the following:
i. How much water (mm/yr) reaches the root zone through capillary rise?
i. How much water seeps out from the groundwater to the surface water in an average
year (mm/yr)?
L How much water evaporates directly from interception in mm/yr?
v. How much is the total evapotranspiration (mm/yr) in the catchment in an avera
year?
