Two piezometers are located 1000 ft apart with the bottom located at depaths 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 piezometr and 40 ft in the shallow one. Assume the hydraulic conductivity is 0.0002 ft/s.
a) Use the Dupuit equation to calculate the height of the water table midway between the piezometers.
b) Find the flow rate per unit thickness for a section miedway between the wells.
