More about IAHS International Commission on Tracers
The International Commission on Tracers (ICT) is a scientific commission of IAHS that promotes the use of tracer approaches to investigate the hydrological cycle and material dynamics across hydrological sciences. Tracers are naturally occurring or anthropogenic substances that provide information across spatial scales from points to large basins and temporal scales from days or weeks to millions of years. The Commission focuses on using tracers to evaluate water sources, pathways, residence times, transport processes, and solute dynamics, including processes across watershed, topographic, geological, and climatic boundaries. ICT is one of the Commissions of the International Association of Hydrological Sciences (IAHS) and promotes application of tracer techniques in all branches of hydrology.
Tracers are substances occurring in the environment naturally or introduced by men whose spatial and temporal differentiation is used to infer information on the pathways and dynamics of water and solutes movement in surface and ground water.
