A lake with a drainage area AD has a surface area of AL and an average depth of zL. The long-term rates of precipitation and evapotranspiration for the portion of the drainage basin are PD and eD, respectively. For the lake itself the average rate of precipitation and evaporation are PL and eL, respectively. Average rate of stream outflow is Q. There is no groundwater inflow or outflow to the basin. a. Identify the units (Length[L], Time [T], Mass [M],...

During the month of March, the average river inflow to a reservoir is 3 m’/s while the dam bottom outlet releases 10 m²/s. Total rainfall for the month is measured as 20 mm uniformly distributed. The average seepage from the reservoir is estimated 0.5 m3/s. The surface areas of the lake are measured from aerial photos as 11.7 and 10.3 km2 and also the staff gauge readings of water surface are recorded as 107.2 m and 105.2 m in the...
