Q2: A) At the beginning of a given day a reservoir has a surface area 30 Km². The inflow to the reservoir during the day was measured to be 80m/s and the reservoir outflow was measured as 15m/s. In addition, the day was dry and the seepage is 10% of the inflow. Assume the area of the reservoir does not change significantly by the end of the day. Determine the reservoir evaporation in mm/day where the reservoirs level is decreased 2 cm?
