Effect of faults and barriers on groundwater flow and solute transport. This project will address the role of faults and dykes on groundwater flow and solute transport. Faults and dykes can act as barriers to groundwater flow, yet faults can also be conduits for flow through otherwise impermeable layers. Understanding their role is critical to assessing the impacts of mining, unconventional gas and water resource developments. This project expects to develop new methods to quantify groundwater f ....Effect of faults and barriers on groundwater flow and solute transport. This project will address the role of faults and dykes on groundwater flow and solute transport. Faults and dykes can act as barriers to groundwater flow, yet faults can also be conduits for flow through otherwise impermeable layers. Understanding their role is critical to assessing the impacts of mining, unconventional gas and water resource developments. This project expects to develop new methods to quantify groundwater flow through and along faults and dykes by combining geological, hydraulic and geochemical approaches with detailed 3D numerical models. The expected outcome will be an improved understanding of the role of faults and barriers in subsurface hydrology, and an improved ability to model complex groundwater systems.Read moreRead less

Summary
Australian National Facility for Noble-Gas Radio-Isotope Measurements. Australian national facility for noble-gas radio-isotope measurements:
This facility is designed to provide researchers with the ability to accurately date water and ice cores using the natural radio-isotopes in the sample. Radiocarbon dating has been a revolutionary tool in providing answers to a range of questions in anthropology, archaeology and the earth sciences. However, radiocarbon dating has a strong limitation in th ....Australian National Facility for Noble-Gas Radio-Isotope Measurements. Australian national facility for noble-gas radio-isotope measurements:
This facility is designed to provide researchers with the ability to accurately date water and ice cores using the natural radio-isotopes in the sample. Radiocarbon dating has been a revolutionary tool in providing answers to a range of questions in anthropology, archaeology and the earth sciences. However, radiocarbon dating has a strong limitation in that it can only date periods from 1000–50 000 years: the use of radioactive noble-gas isotopes can extend this range out to 1 year to 1 million years. This capability in the new facility is expected to support new understanding of processes in artesian reservoirs, ocean currents and geology that may affect questions of water availability, climate and environmental change.Read moreRead less
Groundwater flow age distributions: Understanding open pit mine hydrology. This project aims to improve the estimation of the age of groundwater. Understanding groundwater age is critical for sustainable management and environmental tracers are increasingly used for this purpose.

This project aims to improve the estimation of the age of groundwater. Understanding groundwater age is critical for sustainable management and environmental tracers are increasingly used for this purpose. However, groundwater samples are inevitably mixtures of water of different ages. Since for most tracers the relationship between tracer concentration and age is not linear, different tracers can produce different mean ages for the sample. This project aims to determine whether it is possible to determine moments of the groundwater age distributions from measurements made with different environmental tracers. The project also aims to examine whether the degree of heterogeneity within the aquifer can be determined from the disparity between ages obtained with different tracers. This project aims to tackle the largest problem with using groundwater chemistry to estimate water age – that mixing processes in the subsurface are never known. Solving this problem will allow much more accurate estimates of groundwater velocity and aquifer recharge rates. The groundwater industry contributes an estimated $6.8 billion per annum to the Australian economy, and this project will contribute to the sustainable management of the groundwater resource.Read moreRead less
