Analysis of data from pumping wells near a river

Methods are outlined for determining the hydrologic characteristics of an aquifer draining or drained by a stream; specifically, for determining the transmissibility and storage coefficient of the acquifer and also the effective distance from a pumped well to a line in the stream bed where the water is entering or leaving the aquifer. The procedure is based on the theory of nonsteady flow toward a well steadily discharging from an infinite acquifer hydraulically connected to a fairly straight and long stretch of a stream bed. Application of these methods is illustrated by treating data from the Ingalls area in Kansas.
