Two piezometers are located 1000 ft apart with the bottom located at depths of 50 ft and 350 ft, respectively, in a 400-ft-thick unconfined aquifer. The depth to the water table is 50 ft in the deeper piezometer and 40 ft in the shallow one. Assume that hydraulic conductivity is 0.0002 ft/s.
Use the Dupit equation to calculate the height of the water table midway between the piezometers.
Find the flow rate per unit thickness for a section midway between the wells.
