A confined aquifer is shown in the figure. The aquifer has a hydraulic conductivity of 23 m/day and a void ratio of 0.78. The piezometric heads in the two observation wells L = 2140 m apart are 65 m and 60 m from a common datum. The aquifer has an average depth ot t = 36 m and average width of w = 4.72 km. Recharge 65 EV 60 Aquifer t L 1. Determine the rate of flow of water through the aquifer, in m³/day. (IN 2 DECIMAL PLACES) 2. Determine the seepage velocity in cm/s. (IN EXPONENTIAL FORM AND IN 2 DECIMAL PLACES) 3. Determine the time of travel in days from the head of the aquifer to a point 3 km downstream. (IN 2 DECIMAL PLACES)
