对于通过自然流从均匀含水层流入和/或流出的流动井，发现了电势分布，其中存在与水位下降成比例的泄漏。渗漏含水层具有均匀压缩性和均匀传导性。考虑三种情况：(1) 井对无限渗漏含水层进行排水的情况； (2) 位于圆形含水层中心、外边界水位为零的井； (3) 位于闭合圆形含水层中心的井（即穿过外边界的流量为零）。在这三种情况下制定了放电随时间的变化。获得了相应的非渗漏含水层系统的水位下降分布和流量变化。它显示了地层常数（传输系数、储存系数和泄漏系数）是如何从恒定水位下降下的井流量变化中获得的。
Potential distribution is found for a flowing well discharging by natural flow from a uniform aquifer into, and/or out of, which there is leakage in proportion to the drawdown. The leaky aquifer is of uniform compressibility and of uniform transmissibility. Three cases are considered: (1) that of a well draining an infinite leaky aquifer; (2) that of a well at the center of a circular aquifer with zero drawdown on its outer boundary; (3) that of a well situated at the center of a closed circular aquifer (that is, the flow across the outer boundary is zero). The variation of the discharge with time is formulated in the three cases. The draw-down distribution and the discharge variation for the corresponding systems of nonleaky aquifers are obtained. It is shown how the formation constants (the coefficient of transmissibility, the coefficient of storage, and the coefficient of leakage) are obtained from variations in the rate of discharge of wells flowing at constant drawdown.
