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. However, groundwater samples are inevitably mixtures of water of different ages.

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

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

This project aims to deliver an accurate and reliable seasonal streamflow forecasting system for Australian water users by developing a flexible rainfall-runoff modelling approach integrated into a Bayesian inference and prediction framework. These scientific developments aim to significantly advance the operational capabilities of the Australian Bureau of Meteorology to deliver robust streamflow forecasts to water agencies such as South East Queensland Water and others across Australia. Accurate predictions of future water flows are of tremendous value to urban and rural Australian communities whose economic prosperity, water security and social well-being depend on reliable estimates of water availability.Read moreRead less
Fish Jenga: metapopulation management for coastal river fish. This project aims to address the escalating threats to coastal freshwater fish from drought, fire, and other disturbances. The project expects to generate new knowledge on contemporary distributions of NSW coastal freshwater fishes, and will develop models of population dynamics to explore the consequences of alternative water management and disturbance scenarios.

This project aims to address the escalating threats to coastal freshwater fish from drought, fire, and other disturbances. The project expects to generate new knowledge on contemporary distributions of NSW coastal freshwater fishes, and will develop models of population dynamics to explore the consequences of alternative water management and disturbance scenarios. The expected outcome of the project is to revolutionise management by replacing the current practice of managing river basins separately, with a framework that accounts for among-basin linkages that are essential for the long-term persistence of fish populations. Significant benefits include more efficient use of water resources and improved conservation outcomes for native fish.Read moreRead less
Understanding, measuring and managing the benefits of urban waterways. This project aims to improve understanding of the contribution of urban waterways to enhanced liveability in cities.

This project aims to improve understanding of the contribution of urban waterways to enhanced liveability in cities. Australia needs better water resource management and the rapid growth of Australia’s cities places increased importance on managing natural assets in metropolitan areas. The project focuses on clarifying the link between the benefits of waterways and the measurement techniques used by economists, which in turn inform management choices. The project aims to fill an important gap between the psychology and economics disciplines and outputs should significantly improve the way waterways are valued and managed. This is intended to offer benefits for urban residents and to improve the methodologies used for environmental valuation.Read moreRead less
