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.
