An electrical device for computing theoretical draw-downs of ground-water levels

January 1, 1955

The construction, calibration and use of an electrical "slide rule" for computing theoretical drawdowns of ground-water levels are described. The instrument facilitates the computation of drawdowns under given conditions of discharge or recharge by means of the Theis nonequilibrium equation. It is simple to construct and use and can be a valuable aid in ground-water studies.
