Dye tracing
Dye Tracing
Dye tracing is a method used in hydrology and environmental science to track and trace the flow of water in underground streams and caves.
Pronunciation
Dye tracing: /daɪ ˈtreɪsɪŋ/
Etymology
The term "dye tracing" is derived from the English words "dye", which refers to a substance used to add color to materials, and "tracing", which means to find or discover something by investigation.
Method
Dye tracing involves the injection of a fluorescent dye into a water system. The dye, which is often bright green or red, is then detected downstream using a fluorometer, which measures the intensity of the dye's fluorescence. This allows scientists to determine the direction and speed of the water flow, as well as the presence of any conduits or sinkholes in the system.
