The Gascoyne Region of Western Australia is an emerging Neodymium-rich rare earth district in its early stages of development. The mineral occurrences of the region are complex and their geological distribution and source(s) remain unclear. With the support of all the active explorers in the region, a better understanding of the entire mineral system is sought to maximise exploration efficiency. This project aims to undertake a full assessment of the minerals, their processing and the environmental impact of production to determine the potential of the region. The expected outcome of the project is to develop a world-class rare earth mineral district in Australia, to ensure future supplies of these strategically important metals. Read moreRead less
Improving water market outcomes through a better understanding of market behaviour. The issue of water resources and their sustainable use is probably the most important issue facing the rural sector. The water reform process and its aim to secure water for the environment will cause economic and social pain and result in structural change within the irrigation sector.

The issue of water resources and their sustainable use is probably the most important issue facing the rural sector. The water reform process and its aim to secure water for the environment will cause economic and social pain and result in structural change within the irrigation sector. Properly functioning water markets will play an instrumental role in facilitating this process by providing water for the environment and allowing water to move between competing resources. This study will enable policy makers and water managers to optimise the positive outcome of water markets and increase the likely success of programs to purchase environmental water.Read moreRead less
Climate variability, water allocation and land use change impacts on surface-groundwater interactions and salinity discharge. This project contributes to the national research priority of an Environmentally Sustainable Australia and its three sub-priorities: Water-a critical resource; Overcoming salinity and acidity; and Responding to climate change and variability as well as to the National Water Initiative goal: connected surface and groundwater resources managed as a single resource. These em ....Climate variability, water allocation and land use change impacts on surface-groundwater interactions and salinity discharge. This project contributes to the national research priority of an Environmentally Sustainable Australia and its three sub-priorities: Water-a critical resource; Overcoming salinity and acidity; and Responding to climate change and variability as well as to the National Water Initiative goal: connected surface and groundwater resources managed as a single resource. These embody the clear imperative in Australia to improve the management and use of our stream and groundwater systems in the face of long-term climate variability and changing water use. Knowledge gained from this study of coupled surface-groundwater systems in nationally important catchments will be used to improve water allocation and use strategies and salinity mitigation.

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. Since for most tracers the relationship between tracer concentration and age is not linear, different tracers can produce different mean a ....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. 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

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
Surface-ground water interactions and increasing salinity in the upper Hunter River. Australia's first salinity trading scheme, to limit impacts of industrial saline wastewater discharges, operates in the Hunter Region, NSW. Despite it, a recent audit suggests stream salinity levels will continue to rise over the next century. No assessment tools are available to identify causes of salinity increases in sub-catchments of the Hunter.

Australia's first salinity trading scheme, to limit impacts of industrial saline wastewater discharges, operates in the Hunter Region, NSW. Despite it, a recent audit suggests stream salinity levels will continue to rise over the next century. No assessment tools are available to identify causes of salinity increases in sub-catchments of the Hunter. This severely limits rehabilitation strategies aimed at addressing river salinity. Current rehabilitation focuses on revegetation of recharge and discharge areas, with limited understanding of the primary local drivers for salinity, and without assessment of whether rehabilitation is addressing or exacerbating problems. This project aims to supply that understanding.Read moreRead less
Analysis of Possible Rules for Interstate Water Trading by the Australian Capital Territory. Rules will be studied and modelled for allowing ACT water trading with other states, within an agreed abstraction cap. The aim is to find administrative, constraining and price-setting rules that maximise the economic gain of trading to Australia, bearing in mind environmental constraints, infrastructure costs, transaction costs, and equity.

Rules will be studied and modelled for allowing ACT water trading with other states, within an agreed abstraction cap. The aim is to find administrative, constraining and price-setting rules that maximise the economic gain of trading to Australia, bearing in mind environmental constraints, infrastructure costs, transaction costs, and equity. Innovative challenges for the rules will be allowing ACT to sell water now but buy it back later, thus providing for long term population growth; and handling the differences between ACT's spare storage capacity and urban uses, and the downstream irrigation uses with which trade is most likely.Read moreRead less
Developing a decision support system for the management of road runoff for water quality protection. Multiple stakeholders share a vested and often significant financial commitment to ensure water quality standards.

Multiple stakeholders share a vested and often significant financial commitment to ensure water quality standards. These industries, in turn, are vital to the social and economic sustainability of many rural communities in Australia. Recent climatic trends of increasing drought episodes and related natural disasters such as bushfires are expected to increase the delivery of sediments and associated pollutants to streams. The proposed DSS will allow testing of various management scenarios with respect to road position and layout, thereby providing a planning and management tool, and a method to educate the practitioners involved in environmental management in Australia.
