A confined aquifer has a source of recharge as shown in the figure. The hydraulic conductivity of the aquifer is 40m per day and its porosity is 0.25. The piezo metric head in the two wells with 13.25 m apart are 65m and 60m respectively from a common data. The average thickness of the aquifer is 25m and the average width is 4km. a. Compute the rate of flow through the aquifer in cu.m per day. b. Compute the seepage velocity c. Compute the time of travel from the head of the aquifer to a point 4 km downstream in days.
