Ground Water Flow through Layered Soils

Water level measurements have been taken from two observation wells located approximately 100 meters apart. The depth of water in Well 1 is 59.6 meters and the depth at Well 2 is 39.6 meters. The water levels in both wells have been nearly the same over a period of one month. Three soil layers are sandwiched between two imperious layers above and below. Layer 1 has a thickness of 20 meters and a coefficient of permeability of k1=10^-7 meters/s. Layer 2 has a thickness of 10 meters and k2=10^-6 m/s. Layer 3 is 5 meters thick with a k3=10^-5 m/s. The estimated width of this section of layered soils is 30 meters. What is the daily flow in cubic meters/day through this section of layered soils?
