A confined aquifer has a source of recharge as shown in the figure. The hydraulic conductivity of the aquifer is 35 m/day with porosity of 25%. The piezometric head surface in the two observation wells 1000 m apart are at elevation 75 m and 65 m, respectively from the common datum. The aquifer has an average thickness of 4 m and an average width of 4 km. a. Calculate the rate of flow of water through the aquifer in cubic meters per day. b. Calculate the seepage velocity in meters per day. c. Calculate the time of travel from the head of aquifer to a point 4 km downstream in days.
