Geospatial Applications Of Cave Resource Data To Better Understand Epikarst And Unsaturated Zone Groundwater Flow Path Development, Sierra M. Heimel, Benjamin W. Tobin

Faculty, Staff, and Affiliated Publications--KGS

The unsaturated zone is a critical component of karstic groundwater systems and is shown to provide substantial storage capacities. Understanding the spatial patterns and controls on flow path activation is often a challenge. Previous research focused on remotely sensed data or inferential analyses to quantify these patterns. Here, we use two cave systems—one in Arizona, USA and a second in Kentucky, USA—to show the value of the cave survey and inventory data in the direct observation of speleogenesis and unsaturated zone processes. Using geospatial statistical analyses, we show that passage size varies with distance from some faults, indicating that these …
