Analysis and Interpretation of Data from Tracer Tests in Karst Areas
William K. Jones


Qualitative tracer tests are used to determine flow connections between accessible input and output points and to delineate karst drainage basins for reconnaissance studies. Quantitative tests, which measure the amount of tracer recovered over time and the flow (discharge) of the input and output sources, provide additional insight into the flow processes and mechanisms within the aquifer. The processes acting on a conservative tracer determine the shape or pattern of the dye recovery curve. The dye recovery patterns is determined by 1) the conduit network pattern, 2) the flow characteristics of the aquifer, and 3) the adsorption and dispersion characteristics of the tracer.
