That breakthrough curve is 1. a plot of relative concentration versus time, where relative concentration is defined as c/co with c as the concentration at a point in the ground-water flow domain, and co as the source concentration [22]. 2. a plot of tracer concentration, c, versus time, t, for a ground-water tracing study in karst conduit for the purpose of quantitatively determining how much tracer mass was recovered, mean time of travel, mean tracer flow velocity, and related hydraulic flow and geometric parameters. synonyms: recovery curve; tracerbreakthrough curve; tracer-recovery curve.?

Release of the first edition of this lexicon was well received and resulted in two printings. The first edition is again in short supply, but rather than going through a third printing, an updated edition was deemed appropriate. Since the release of the first edition, additional definitions related to biospeleology, courtesy of Dr. William R. Elliott of the Natural History Division of the Missouri Department of Conservation, have been added. Additional definitions obtained from the Australian Speleological Federation also have been added.


The National Center for Environmental Assessment-Washington Office (NCEA-W) has prepared this document for the benefit of the regional offices and public in general due to the need to understand the terminology common to the field of karst. It is a glossary of most terms that have some relationship to the field of environmental karst as well as specific karst terms. It includes many foreign terms because much of the karst research is conducted in foreign countries and published using local terminology. In many instances, common environmental terms are defined in such a way as to specifically reference karstic phenomena.




Several attempts to classify karst terminology in an organized manner have been attempted in the past. The last few glossaries of karst terminology were organized in the late 1960s and published in the early 1970s. Since that time, many new terms related to karst in general have come into use throughout the world while other older karst terms are seldom used nowadays. In the mid 1990s the British Cave Research Association (BCRA) published and updated a dictionary that covers the general area of karst and caves, but did not focus on environmental issues.

As a final note, it should be pointed out that a list of references for the definitions are included at the back of this glossary and citations are provided when appropriate. In many instances, duplication of definitions from previous glossaries were employed to avoid changing the original definitions. However, efforts were not always attempted to cite the exact source for each definition as this would have greatly lengthened this already excessively long manuscript; secondary citations have been provided. Exact citations would also have resulted in confusion where several definitions were utilized in the writing of a single clear definition for any particular term. In no instance was it intended that the work of others be appropriated, only that this glossary be as comprehensive and clear as possible while avoiding excessive clutter. Also, where definitions were deemed to be incorrect or poorly worded, alternatives have been written.
