Applied Methods of Karst Hydrology

Karst landscape/aquifer systems are estimated to constitute about 15% of the earth's ice-free land surface and supply water resources to up to 25% of the world's population. But karst hydrogeology is extremely challenging and complex, and karst landscape/aquifer systems have difficult water supply problems both with access, as surface water can be lacking, and quality, as available groundwater may be susceptible to contamination.

Part 1 of this webinar series discusses the principles of karst hydrogeology and important methods for studying karst groundwater in epikarst, underground rivers and at springs. Specialized methods, different from those used in porous media or other "traditional" groundwater environments, are required to understand and monitor karst groundwater. These methods include identification of subsurface flow paths through direct exploration and mapping, dye tracing, potentiometric surface mapping and geophysics (geophysical and dye tracing methods are detailed in other webinars). Interpreting the background geochemical environment within karst flow systems can be useful for understanding aquifer evolution, microbial ecology and the fate and transport of contaminants. We will discuss high resolution methods for characterizing these environments.

This webinar is the first of a two-part series on Karst Hydrogeology. Although both webinars are designed to complement each other they can also be viewed independently.

Part 1 Highlights include:
  • Introduction to karst aquifer/landscape systems
  • Water-related environmental problems in karst systems
  • Methods to understand geometry and behavior of karst flows
  • Methods to monitor karst groundwater

Instructors Bio

Dr. Chris Groves

Dr. Chris Groves is the director of the Crawford Hydrology Laboratory and Hoffman Environmental Research Institute and is a Distinguished University Professor of Geography at Western Kentucky University. Since receiving a PhD In Environmental Sciences at the University of Virginia in 1993, Dr. Groves has developed an active international research program in basic and applied hydrogeology, geochemistry, and water resources. He currently serves as a co-leader of the United Nations Scientific Program "Environmental Change and Sustainability in Karst Systems," and as a member of the Governing Board of the International Research Center on Karst under the auspices of UNESCO. In 2013 he was nominated by China's Ministry of Land and Resources for the China Friendship Award, that nation's highest award for foreign experts. With more than 30 years of international experience in karst hydrogeology, Dr. Groves provides experienced oversight of karst groundwater flow investigations for Crawford Hydrology Laboratory.

Ms. Lee Anne Bledsoe

Mrs. Bledsoe is the manager for the Crawford Hydrology Laboratory at Western Kentucky University. She supervises all daily workings of the lab, including laboratory analysis, QA/QC, and field work, and communicates with clients. She has worked on dye traces for groundwater basin mapping, effluent and sewer pipe break investigations, determining groundwater flow routes from factories and quarries, and determining spring recharge areas.

Mrs. Bledsoe also coordinates and assists in training and outreach events for the Hoffman Environmental Research Institute at Western Kentucky University. Before joining the Hoffman team, she worked for private research institutes and the National Park Service on water quality, hydrology, ecosystem restoration, and public health research projects. She is a Registered Sanitarian with the Department of Public Health for the State of Kentucky and is a certified onsite wastewater disposal inspector. Ms. Bledsoe is currently pursuing a Master of Science degree in Geoscience at Western Kentucky University.
