Norris, Laura A., Cassie E. Simpson, and Trent Garrison. "Discovering Relationships Between Surface And Groundwater Velocities Through Dye Tracing In Fayette Co, Ky." 2016. doi:10.1130/abs/2016se-272937.
In mature karst regions, water may flow through large subsurface conduits, expediting flow to surficial karst springs. In the fall of 2015, a dye trace was performed in the Middle Ordovician karst of Lexington, Fayette County, Kentucky in order to measure ground water velocities. Other aspects of the study include (1) comparing these velocities to surface water velocities at discharge points (springs) and (2) comparing karst conduit velocities to granular velocities from previous studies in the region. The locations selected for study include (1) the “Campbell House Sinkhole," (2) McConnell Springs, and (3) Preston’s Cave Spring.
