Karst Hydrogeologic Investigation Research Procedures

The following proposed research procedures are based upon methods originally developed by Dr. Nicholas C. Crawford to investigate the flow of groundwater in karst aquifers. These time-proven procedures have been used by Dr. Crawford, as well as Crawford Hydrology Laboratory, formerly Crawford and Associates, on over 900 dye traces since 1970. The text presented on this Web Site is abridged from the materials presented in "Karst Groundwater Investigation Research Procedures", copyrighted 1994-1998, Crawford Hydrology Lab.
