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 offer new knowledge about why commuter cycling has failed to increase at a time when leisure cycling grows exponentially. The project seeks to provide evidence about what cycling enables people to achieve through analysis of a database of media discourses, policies and most importantly the experiences of cyclists. Expected outcomes include an enhanced understanding of cycling as response to congestion and improved policy strategies for increasing purposeful cycling in cities including moving the focus from cycling participation rates to cultures of cycling. Australia will benefit from cycling growing as a mode of transport to attenuate traffic congestion in metropolitan centres.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 revise understandings of First Nations economic circumstances by investigating disparities between First Nations and non-Indigenous financial wealth. It expects to generate knowledge of the size of the ‘wealth gap’ and identify the structures that cause its contemporary reproduction and analyse policy options to address these disparities. Expected outcomes of the project include new knowledge about the Indigenous-settler wealth gap and the development of a research literature on approaches to addressing the wealth gap in Australia. This should provide significant benefits including a clearer understanding of the nature and causes of economic disparities between First Nations and non-Indigenous people in Australia.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. 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 exten ....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. 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 will derive air-sea carbon dioxide (CO2) exchange signals, which permit straightforward evaluation of the deep Atlantic’s role in millennial atmospheric CO2 changes under various climate conditions. The intended outcome of this project is to substantially improve our understanding of the mechanisms that govern the global carbon cycle. This should provide significant benefits including the assessment of models used to predict future global warming due to anthropogenic CO2.Read moreRead less
Understanding total long-term sea-level consequences. This project addresses the urgency in long-term infrastructure planning to understand the long-term "equilibrium" sea-level-change consequences from today’s exceptionally rapid climate change. Understanding this requires detailed sea-level reconstructions back to warm periods with similar CO2 levels to today (~3.5 million years ago), but these remain insufficiently defined. To advance, the project will deliver a next-generation, multi-million ....Understanding total long-term sea-level consequences. This project addresses the urgency in long-term infrastructure planning to understand the long-term "equilibrium" sea-level-change consequences from today’s exceptionally rapid climate change. Understanding this requires detailed sea-level reconstructions back to warm periods with similar CO2 levels to today (~3.5 million years ago), but these remain insufficiently defined. To advance, the project will deliver a next-generation, multi-million-year sea-level reconstruction that includes dynamically evolving (time-dependent) interactions between critical climate factors. This will then be applied with other palaeoclimate data to reconstruct equilibrium relationships between sea level, temperature, and CO2 at currently unattainable precision. Read moreRead less
