The use of electrical resistivity surveys to locate karst conduits has shown mixed success. However, time‐lapse electrical resistivity imaging combined with salt injection improves conduit detection and can yield valuable insight into solute transport behaviour. We present a proof of concept above a known karst conduit in the Kentucky Horse Park (Lexington, Kentucky). A salt tracer solution was injected...
The US Geological Survey’s (USGS) National Hydrography Dataset (NHD) is a comprehensive set of digital spatial data representing the surface water of the United States for use with geographic information systems (GIS). The NHD digital product was designed to also allow incorporation of various groundwater data. The Kentucky Geological Survey (KGS) and Kentucky Division of Water (KDOW) have compiled...
