承压含水层中流体的非稳态流动可以通过线性、抛物线、偏微分方程来近似。编写了一个数字计算机程序来基于隐式有限差分技术求解这些方程。计算值与简单几何形状的均质、各向同性含水层的解析解相比毫不逊色。使用这种技术对新斯科舍省穆斯科多博伊特港的含水层进行了分析。修改数字模型中的含水层参数，直到计算结果符合泵测试数据。结果表明，该含水层将在大约 100 天内达到平衡，并且很容易为 Musquodoboit 港村提供充足的水源。作为对该问题的数字模型的检查，还构建了该含水层的电模拟；得到的两种解决方案相比起来毫不逊色。
The unsteady-state flow of a fluid in a confined aquifer can be approximated by linear, parabolic, partial-differential equations. A digital-computer program was written to solve these equations based upon an implicit finite-difference technique. Calculated values compared favorably with analytical solutions for homogeneous, isotropic aquifers of simple geometry. An analysis of an aquifer at Musquodoboit Harbour, Nova Scotia, was made using this technique. Aquifer parameters in the digital model were modified until the results computed fitted the pump-test data. The results indicate that this aquifer would come to equilibrium in about 100 days and would easily provide an adequate supply of water for the village of Musquodoboit Harbour. As a check of the digital model for this problem an electric analog of this aquifer was also constructed; the two solutions obtained compared favorably.
