The distribution of 3H and its decay product 3He in aquifers can be utilized to calibrate groundwater flow and transport models, either by using the two isotopes as separate tracers, or by using the 3H/3He age. A variety of modelling approaches has been applied to 3H/3He data sets in hydrogeological settings ranging from simple homogeneous sands to fractured bedrock systems. These studies indicate that tritium concentrations alone, as well as 3H/3He data provide powerful calibration targets for groundwater flow and transport models. 3H/3He data are also sensitive to longitudinal and transversal dispersion and to large-scale mixing and can be used to quantify these processes.
