Question

Situation 01. An evaporation pan was set-up adjacent to a reservoir. The depth of water in the pan at
the beginning of the observation was 200mm. In two weeks of observation, there was a total rainfall
of 55mm and 20mm of water was removed from the pan to keep the water level within the pan
capacity. If the depth of water in the pan after two week was 185mm, Compute the evaporation of
the reservoir (in/day) if the pan coefficient is 80%.
Situation 02. Using Green-Ampt Infiltration model, calculate the infiltration rate for a loam soil with
an effective saturation of 32.3%, and the intensity of rainfall is 0.004 mm/s. Assume ponded
conditions within 2 hours.

What do you understand by the term evaporation? If you’re a civil engineering technologist where do you apply this evaporation in your civil engineering related projects explain it? A class-A pan was setup adjacent to a lake. The depth of water in the pan at beginning was 77cm. in that week, a rainfall of 37mm came and 15 mm of water was removed from pan to keep the water level in the specified depth. If the depth of water at end of the week was 186.89 mm, calculate pan evaporation. Using suitable pan coefficient, estimate lake evaporation in that week.
