摘要：Tracers of groundwater flow are especially importantfor understanding hydrological systems, rangingfrom small local catchment areas to large regionalbasins. Isotope tracers are valuable tools which can providekey information on groundwater dynamics, as well as directrecharge rate estimates for groundwater renewal.The Water Resources Programme held the first ResearchCoordination Meeting (RCM) on ‘Tritium-3He Dating andNoble Gas Techniques in Water Resources Management:Recharge, Infiltration Conditions and GroundwaterBalance’ on 8–12 Nov. 2010 to focus on this area underCoordinated Research Project (CRP) 1786.
