摘要

Information on fluorescent dyes used for water tracing and the results of six studies are reported. Optical brightener, direct yellow, fluorescein, rhodamine (WT), and other dyes are described and the procedures employed in their use in the field and in equilibration experiments are described. Three of the six studies consisted of investigations of the equilibration with passive detectors of three of the dyes. The absorption of optical brightener on fabric detectors was apparently linear with concentration and with immersion time, while detectors became rapidly saturated with direct yellow. A fifth study was based on a series of dye traces into Royal Spring and Russell Cave Spring in the Inner Bluegrass Karst Region. The most interesting results was the very small value for depth of flow. Fracture traces were identified on topographic maps and aerial photographs in the Inner Bluegrass Karst Region.
