Regulatory design for water quality management in urban catchments. This project aims, through empirical research (i) to evaluate the effectiveness of current regulatory, quasi-regulatory and other policy strategies for water quality management in urban catchments (including total/integrated catchment management); (ii) to provide practical policy prescriptions concerning how through judicious regulatory and institutional design, those problems may be best addressed for the future; and (iii) adva ....Regulatory design for water quality management in urban catchments. This project aims, through empirical research (i) to evaluate the effectiveness of current regulatory, quasi-regulatory and other policy strategies for water quality management in urban catchments (including total/integrated catchment management); (ii) to provide practical policy prescriptions concerning how through judicious regulatory and institutional design, those problems may be best addressed for the future; and (iii) advance regulatory theory by developing a framework for understanding the relative effectiveness of different regulatory regimes in the context of urban catchment management. Its empirical focus is on the Swan-Canning river in Western Australia.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. Innovative challenges for the rules will be allowing ACT to se ....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. 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
Enhancing nutrient retention in soils through management of microbial biomass. Soil microbial-processes are generally studied in relation to mineralisation of nutrients but rarely for their potential to retain nutrients and reduce nutrient leaching. We hypothesise that management of microbial immobilisation will enhance nutrient retention in nutrient enriched soils during seasonal rains. This hypothesis will be tested under strongly seasonal environments of southwest Australia where nutrient lea ....Enhancing nutrient retention in soils through management of microbial biomass. Soil microbial-processes are generally studied in relation to mineralisation of nutrients but rarely for their potential to retain nutrients and reduce nutrient leaching. We hypothesise that management of microbial immobilisation will enhance nutrient retention in nutrient enriched soils during seasonal rains. This hypothesis will be tested under strongly seasonal environments of southwest Australia where nutrient leaching from soils degrades quality of surface and groundwater. We will first investigate pathways and conditions leading to microbial immobilisation. We will then explore the regulation of substrate and nutrient conditions to promote such retention, and subsequently develop management interventions based on microbially-mediated nutrient retention.Read moreRead less
Multi-Objective Optimal Operation of Urban Water Supply Systems. In recent past, there has been a significant shift away from development of new water resources to optimal operation of existing reservoir systems. This project aims to develop a decision support framework to determine optimum operating rules of existing reservoir systems that consider a range of economic, environmental and social criteria, with a strong focus on decision analysis of alternative operating rules. The results of the ....Multi-Objective Optimal Operation of Urban Water Supply Systems. In recent past, there has been a significant shift away from development of new water resources to optimal operation of existing reservoir systems. This project aims to develop a decision support framework to determine optimum operating rules of existing reservoir systems that consider a range of economic, environmental and social criteria, with a strong focus on decision analysis of alternative operating rules. The results of the project will enable water planners to manage their urban water systems efficiently and effectively under a range of long term and short term planning conditions including droughts, while reducing associated environmental impacts.Read moreRead less
Water for Australia's future - reducing fears and increasing acceptance of alternative water sources through public information. Australia is in the midst of a water crisis. Available water sources are dwindling. Alternative water sources are key to Australia's sustainable water future.

Australia is in the midst of a water crisis. Available water sources are dwindling. Alternative water sources are key to Australia's sustainable water future. National and international experiences show that while alternative water treatment technologies are available, public acceptance is the most important factor to determining the successful implementation of alternative water schemes. This project will study public acceptance of a range of alternative water schemes in Australia. It will identify barriers to adoption of these alternatives and highlight preferred options by the community. The information needs of Australians will be identified and optimal communication strategies developed.Read moreRead less
Diffusion and transport of saltwater in coastal aquifers. Saltwater intrusion is a severe environmental problem in coastal regions of Australia, resulting in loss of agricultural land at an alarming rate. This project aims to develop a three-dimensional mathematical model for the simulation and prediction of saltwater intrusion into complex coastal aquifers based on recent advances in the theory of anomalous diffusion, stochastic modelling and numerical methods.

Saltwater intrusion is a severe environmental problem in coastal regions of Australia, resulting in loss of agricultural land at an alarming rate. This project aims to develop a three-dimensional mathematical model for the simulation and prediction of saltwater intrusion into complex coastal aquifers based on recent advances in the theory of anomalous diffusion, stochastic modelling and numerical methods. The parameters of the model such as hydraulic conductivity and porosity will be estimated using multifractal techniques based on field data at the microscale. Once validated from measurements, the model will be used directly for resource management and planning.Read moreRead less

Clean potable water is one of the most important resources for human health and a successful economy. Increasingly, subterranean aquifers are used for storage and recovery of water. These aquifers contain dynamic ecosystems, but little is known about species composition or about the importance of the presence of various species for water quality. We will use the latest laboratory techniques and DNA identification methods to provide a template for determining ground water diversity and food web dynamics throughout Australia. This project will lead to a better understanding of how to manage ground water in a sustainable manner.Read moreRead less

The project will aim to collate data and map base-level distribution patterns of molecular and microbial markers of human sewage and natural/agricultural contamination with reference to diurnal and seasonal fluctuations. These data will then be used to develop decision support systems that predict contaminant dispersion and identify high-risk contamination sources. The diurnal collection of data is expected to show significant variations in the measured parameters associated with time of day, light intensity and temperature. Mapping of the sewage and nutrient loads throughout the year will provide base line data for identifying potential hotspots for targeting system upgrades or improved management programs.Read moreRead less
The Integration of Built and Natural Environmental Datasets in National Spatial Data Infrastructure Initiatives. Delivering sustainable development nationally assumes knowledge about the natural and built environment.

Delivering sustainable development nationally assumes knowledge about the natural and built environment. This requires access to data about these two environments which is facilitated by establishing a National Spatial Data Infrastructure (NSDI). The problem in Australia is that the states are the custodians of large to medium built and natural datasets while the Federal Government is the custodian of small scale natural datasets. While Australia has seen some success, the integration of these datasets is hampered by jurisdictional, institutional, administrative and legal issues. This research will investigate the differences in these forms of data and the justification and policy framework to integrate them in a NSDI.Read moreRead less
