实践中的水文地质学家很清楚含水层的非均质性如何影响我们做出准确预测的能力。许多所谓的“异常”传输观测可以用(但不是明确地归因于！)含水层材料的非均质性-从快速、连接良好的流动路径导致早期到达，到导致反扩散和长尾矿的低渗透透镜体。同样，许多水文地质学家可能熟悉从不同含水层测试中获得截然不同的参数估计的问题，这也常常可归因于非均质性和特定测试所感知的含水层体积，即尺度效应。
The practicing hydrogeologist is well aware of how aquifer heterogeneities influence our ability to make accurate predictions. Many so-called “anomalous” transport observations can be explained by (but not definitively attributed to!) heterogeneity in aquifer materials—from fast, well-connected flow paths causing early arrival to low-permeability lenses that contribute to back-diffusion and long tailing. Similarly, many hydrogeologists are likely familiar with the problem of obtaining markedly different parameter estimates from different aquifer tests, which again can often be attributed to heterogeneities and the aquifer volume sensed by a given test, that is, the scale effect.
