在过去几年中，与水坝和其他工程的设计和建造有关的深入的地质调查已经确定了深基岩溶液的普遍存在，这种溶液发生在地下水位以下。虽然这种深层水流及其解法完全符合水力学原理，但地下水流最佳深度及其解法的一个重要方面是地下环流的调整问题。随着这种调整的完善，深层流动和溶解逐渐减少，饱和带上部的流动和溶解相应增加。在循环的后期阶段，洞穴形成可能发生在较高的水平，通过高水平的主管道的侧流的浓度。在早期阶段，水流并不集中，而是分布在整个垂直剖面上，沿沿着弧形路径定向，在向上弯曲到排放点之前，这些路径深深下降。
The intensive geologic investigations during the past few years in connection with the design and construction of dams and other engineering works have established the common existence of deep bedrock solution, which has occurred well below the water table. Although this deep flow and solution are entirely harmonious with hydraulic principles, an important aspect of the problem of the optimum depth of ground-water flow and solution is the matter of adjustment of the subsurface circulation. As this adjustment becomes more perfect, deep flow and solution progressively diminish and flow and solution in the upper levels of the zone of saturation increase correspondingly. In the latter stages of the cycle, cave formation probably occurs at higher levels by the concentration of lateral flow through high-level master-conduits. In the earlier stages, flow is not concentrated but is distributed throughout the entire vertical section, oriented along arcuate paths which descend deeply before recurving upward to the point of discharge.
