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
SCANEM : A Scanning and Inspection Method for Urban Pipeline Systems. Water and sewage utilities are crucial factors limiting economic growth and urban amenity. However many of these facilities are subject to corrosion, fracture and collapse and new strategies are now required to provide a sound basis for systematic remediation and replacement.

However many of these facilities are subject to corrosion, fracture and collapse and new strategies are now required to provide a sound basis for systematic remediation and replacement. Suitable strategies involving a structural audit and statistical analysis have been proposed by CSIRO and Tyco Water. However new geophysical inspection methods are now required to provide the key physical parameters relating to pipeline condition. Hopefully the EM inspection tool resulting from this project will provide the industrial partners with a unique capacity to satisfy a major global market.Read moreRead less

Data-driven water quality treatment management decision support system. This project aims to develop a robust decision support system to predict manganese and the character and concentration of dissolved organic matter in drinking water reservoirs, using intelligent algorithms and data collected through remote autonomous instrumentation. These predicted water quality parameters could be used as model input variables to provide real-time decisions for plant operators on the required treatment regime for incoming raw water, and advise them on the optimal reservoir offtake depth. This will potentially minimise treatment costs and health risks for consumers. The ultimate goal is to significantly enhance current water supply management practices.Read moreRead less
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.

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

Smart management of disinfectant in chloraminated water-supply systems. This project aims to develop an adaptive, real-time control system for managing disinfectant residuals in chloraminated water supply systems. While chloramine delivers microbiologically safe drinking water in warmer climates and in long distribution systems, it is largely unpredictable, costs water utilities millions of dollars annually, and has uncertain benefits. This project’s control system will be guided by quantitative models formulated from multi-pronged, fundamental experiments. The project will quantify microbial chloramine decay and determine mechanisms to increase predictability. The project will develop and demonstrate a real-time control technology which delivered microbiologically safe, cost-efficient drinking water to people in warmer climates, despite warming climate and increasing population.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.

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
Improving water quality modelling by better understanding solute transport. Poor stream water quality is a critical problem in Australia and globally. Stream water quality depends directly on pathways and time taken for water to transport pollutants through catchments.

Poor stream water quality is a critical problem in Australia and globally. Stream water quality depends directly on pathways and time taken for water to transport pollutants through catchments. Predicting these pathways is highly challenging and currently requires specialised data. This project aims to better model the movement of water from rainfall to streams, enable greatly improved use of water quality data routinely collected in Australia's catchments and thereby better predict water quality behaviour. Proposed field studies aim to support this development. The outcomes sought are improved planning and management of water quality in our rivers, lakes and estuaries, improved health of these water bodies and improved water supplies.Read moreRead less
Erosion of embankment dams and dam spillways. In excess of $250M is spent annually to maintain, upgrade, improve safety and monitor performance of Australian dams. Improved methods for assessing both spillway and internal erosion, the cause of 50 per cent of embankment dam failures and incidents requiring repairs, will be developed, maximising dam safety and minimising maintenance expenditure.
Synthesis of Activated Carbon Supported Zero Valent Iron Nanoparticles and Application to Contaminant Degradation in Benthic Sediments. Sediment contamination is a major problem in harbours and estuaries around Australia. For example, in Sydney Harbour, a total fishing ban has been implemented as a result of excessive levels of dioxins and benzofurans in fish tissues. There is also concern at the possibility of large scale contamination of Botany Bay as a result of historic industrial activity a ....Synthesis of Activated Carbon Supported Zero Valent Iron Nanoparticles and Application to Contaminant Degradation in Benthic Sediments. Sediment contamination is a major problem in harbours and estuaries around Australia. For example, in Sydney Harbour, a total fishing ban has been implemented as a result of excessive levels of dioxins and benzofurans in fish tissues. There is also concern at the possibility of large scale contamination of Botany Bay as a result of historic industrial activity around the Bay. While dredging and on-land treatment of sediments is being adopted at the most severely contaminated sites, the cost of this approach is exorbitant. For sites where removal of contaminated sediments cannot be justified, the approach proposed in this study of a technology that entraps contaminants and enhances their in situ biodegradation is potentially a way forward.Read moreRead less
