IL An unconfined aquifer flows horizontally 2000 R in a soil with a K = 10 ft/day, followed hy 3000 ft in a soil with a K of 9 fi/day.

The water level at the beginning of this reach is50 fl and at the end of this reach (5000 ft away) is 45 ft, measured above the bottom of the confining layer. The flow is horizontal and one-dimensional. What is the flow rate per unit width? (12 pt)
