Clinch River Nuclear Site Early Site Permit Application Part 2, Site Safety Analysis Report Epigenic and hypogenic karst in the context of basinal groundwater flow. The figure shows mainly gravity-driven flow in an idealized homogenous basin. In reality, most sedimentary sequences are highly heterogeneous, and gravity-driven flow interacts with other flow mechanisms. From Reference 2.5.1-289.

Clinch River Nuclear Site Early Site Permit Application Part 2, Site Safety Analysis Report Schematic illustration of isolated phreatic maze cave development within a mixing zone localized near to a fault. Rising water along the fault intersects the shallow karst aquifer, and creates cavernous porosity in the mixing zone. If rising fluids were initially hydrothermal, alteration of the bedrock along fractures may result in slightly more resistance to weathering, and result in a cave located within a hill on the land surface. From Reference 2.5.1-296.
