Abstract

Environmental tracer data can be used to determine pathways and timescales of environmental processes such as groundwater recharge rates and fluxes. This can be achieved by using such data as direct constraints for the development of numerical groundwater models. This research explores the use of flow and solute transport models to derive a more rigorous interpretation of environmental tracer data in complex aquifer systems. The joint simulation of multiple environmental tracers including tritium, chlorofluorocarbons and carbon-14 was illustrated in this thesis to better explain the observed simultaneous occurrence of young and old groundwaters in aquifers in Western Australia's Pilbara region.
