Observed streamflow generation changes: better understanding and modelling. This Project aims to investigate drivers and triggers of variable streamflow response during and after drought and develop modelling strategies and model structures more robust to changing streamflow response. In many catchments during the Millennium Drought, streamflow generation was less than expected and hydrologic models performed poorly. After the drought, streamflow generation is yet to recover in some catchments. ....Observed streamflow generation changes: better understanding and modelling. This Project aims to investigate drivers and triggers of variable streamflow response during and after drought and develop modelling strategies and model structures more robust to changing streamflow response. In many catchments during the Millennium Drought, streamflow generation was less than expected and hydrologic models performed poorly. After the drought, streamflow generation is yet to recover in some catchments. This Project expects to generate new knowledge about variable streamflow response to drought and develop strategies and models to robustly simulate runoff during and after changed conditions, which should provide significant benefit via better understanding and modelling of streamflow response under changing conditions.Read moreRead less

This project aims to assess the risk of low rates of mixing in sub-tropical drinking water supply reservoirs, using environmental monitoring and numerical modelling. Emerging evidence suggests sub-tropical drinking water supply reservoirs could transition to low mixing states with increasing age and projected changes in global climate. While this risk is poorly understood, it could significantly affect the long-term reliability of water supply and potable water treatment costs. Addressing this knowledge gap is expected to develop effective management responses to ensure the long term sustainable use of these water resources.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.

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
Vulnerabilities for environmental water outcomes in a changing climate. This project aims to assess the vulnerability of freshwater ecosystems to extended droughts in a variable and changing climate.

This project aims to assess the vulnerability of freshwater ecosystems to extended droughts in a variable and changing climate. Governments around the world are investing in the restoration of regulated river systems with environmental water. However, the risks of climate change for environmental water management are seldom considered. This project will model the change in environmental and consumptive water use during extended dry periods, and couple this to models of ecological dynamics and failure thresholds. This will improve the success of Australia’s major environmental water programs in sustaining benefits through future multi-year droughts.Read moreRead less

The project aims to increase the yield of molecular negative ion sources by improving our understanding of the formation of ion beams from plasma sources and expand our knowledge of molecular negative ion generation in plasma environments leading to brighter ion beams. For example, understanding cancer requires cellular level tools to map how cells are changing. These maps are made using ion beams which are scanned across cells to remove material that is analysed at the atomic and molecular level. Ion beams are produced from plasma sources, but much of their operation is not understood. Such improved ion beams are expected to enable inexpensive and fast cellular level pathology at even small hospitals to tackle cancer for society’s benefit.Read moreRead less
