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

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. This severely limits rehabilitation strategies aimed at address ....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. 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
Gambling-related harm in Northern Australia: A Geographic Information Systems (GIS)-based spatiotemporal analysis of venue catchments. There is growing national concern about the impact of electronic gaming (poker) machines yet little is known about the effects of this gambling in rural and remote areas of Australia. We will develop a database to define the geographic distribution of gambling impacts, the nature of high-risk venues, and the characteristics, both spatial and social, of vulnerable ....Gambling-related harm in Northern Australia: A Geographic Information Systems (GIS)-based spatiotemporal analysis of venue catchments. There is growing national concern about the impact of electronic gaming (poker) machines yet little is known about the effects of this gambling in rural and remote areas of Australia. We will develop a database to define the geographic distribution of gambling impacts, the nature of high-risk venues, and the characteristics, both spatial and social, of vulnerable communities. This will enable the design of much needed harm minimisation strategies and will provide regulatory bodies with insights into the capacity of local communities to absorb the impact of electronic gaming machine venues.Read moreRead less

In the context of recent decentralization of government functions in Indonesia and the Philippines this action research project will test an innovative model of partnership between four communities and local government units aimed at generating new pathways for regional development. Community-based researchers and local government workers will map the social and economic transactions and assets of each local region as a step towards mobilizing these people-centred resources in alternative livelihood projects. Innovative strategies that build upon indigenous and local capacities for sustainable development of a diverse community economy will be explored and implemented.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. 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 associat ....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. 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.

Optimisation of catchment management: stable isotope studies of water storage and yield. Focusing on the Cotter catchment, this project will establish how the water content of soils and tree stems regulates the amount of water used by trees in sub-catchments, and thus how much reaches streams and dams. Small areas supply most of the water yield and this project will help identify where managers should focus efforts to increase yield.
A decadal to inter-decadal streamflow prediction system. This project will develop the first ever decadal streamflow prediction system for Australia, leading to predictions of streamflow for the next 10 years and beyond that take into account both natural climatic variability (driven by factors such as the El Nino Southern Oscillation) and changing greenhouse gas concentrations due to a warming planet.
