The Australian water industry faces the challenge of catering for the potable water demand of a rapidly expanding population with reduced reliability on supply imposed by an increasingly variable climate. Diversified water supply schemes (DWSS) incorporating decentralised systems or reuse sources are touted as a means to handle the inherent weaknesses of centralised urban water supply schemes by potentially drawing 30-50 per cent less demand on their reserves. This research study will provide evidence to support the implementation of best practice DWSS based on an evidence based holistic assessment of their performance considering potable water savings, capital and operation costs, energy demand, as well as environmental and community impacts.Read moreRead less
Resilience of lake ecosystems to water-level manipulation. Which lakes recover from fluctuations in water level and which do not? Manipulations of water levels in lakes will need to intensify as droughts become more frequent. This project will develop robust ways of forecasting how lakes will respond to changes in manipulations of water levels, to minimise extinctions and maintain aesthetics and water quality.
Resolving nitrogen and phosphorus transformations along subterranean estuary - sediment/water interface continuums in carbonate sands. Humans are modifying global nitrogen (N) and phosphorus (P) cycles at an alarming rate. The release of N and P into the environment drives eutrophication, one of the greatest threats to coastal ecosystems worldwide. Globally, there is little effort being made to control increasing N and P emissions. The transport of contaminated groundwater is a major source of N ....Resolving nitrogen and phosphorus transformations along subterranean estuary - sediment/water interface continuums in carbonate sands. Humans are modifying global nitrogen (N) and phosphorus (P) cycles at an alarming rate. The release of N and P into the environment drives eutrophication, one of the greatest threats to coastal ecosystems worldwide. Globally, there is little effort being made to control increasing N and P emissions. The transport of contaminated groundwater is a major source of N and P to the coastal zone and an overlooked driver of eutrophication. Yet, research into the processes that influence N and P transformation in groundwater are scarce, they neglect carbonate sand systems and have ignored the processes in key groundwater transition zones. This project will generate new knowledge that will help us understand the role that groundwater plays in coastal eutrophication.Read moreRead less
Dynamics and management of riverine freshwater lenses. Rivers are the main source of freshwater for many ecosystems in semi-arid zones. River water may seep into the floodplain aquifer, providing an accessible store of low-salinity water within freshwater lenses. The project aims to investigate lens dynamics using numerical groundwater models supported by extensive field data from the lower River Murray, where freshwater lenses are declining. The project aims to model lens extent, growth and dec ....Dynamics and management of riverine freshwater lenses. Rivers are the main source of freshwater for many ecosystems in semi-arid zones. River water may seep into the floodplain aquifer, providing an accessible store of low-salinity water within freshwater lenses. The project aims to investigate lens dynamics using numerical groundwater models supported by extensive field data from the lower River Murray, where freshwater lenses are declining. The project aims to model lens extent, growth and decline in response to natural variations in climate and to changes in land use, river regulation and groundwater pumping. Project results intend to evaluate management options to promote freshwater lenses, with the aim of improving river salinity and floodplain vegetation health.Read moreRead less
Innovative approaches to managing and understanding taste and odour in drinking water systems. Taste and odour (T/O) problems resulting from Cyanobacteria can change consumers' perception of product safety, resulting in many complaints, soaring management and treatment costs, and large financial losses, yet little is known about how they arise.
This project will provide the Australian Water Industry with cost-effective, sensitive, specific, rapid and practical tools for managing and understandi ....Innovative approaches to managing and understanding taste and odour in drinking water systems. Taste and odour (T/O) problems resulting from Cyanobacteria can change consumers' perception of product safety, resulting in many complaints, soaring management and treatment costs, and large financial losses, yet little is known about how they arise.
This project will provide the Australian Water Industry with cost-effective, sensitive, specific, rapid and practical tools for managing and understanding T/O episodes, and will also benefit the aquaculture and food sectors, and the research community. An improved ability to manage geosmin in drinking water, will also have positive repercussions on the Australian environment, by eliminating the need to use environmentally controversial control methods such as copper sulphate dosing.

Adapting for an uncertain future: farmer behaviour in water-stressed basins. Given the future risk of water scarcity, farmers will need to plan for greater farm-level adaptation. Drought and policy reform have inflicted significant economic, social and personal stress upon Murray-Darling Basin rural communities. This project aims to aid water managers and policy makers with a greater understanding of transformational farmer adaptation in order to plan for the economic, social and health impacts ....Adapting for an uncertain future: farmer behaviour in water-stressed basins. Given the future risk of water scarcity, farmers will need to plan for greater farm-level adaptation. Drought and policy reform have inflicted significant economic, social and personal stress upon Murray-Darling Basin rural communities. This project aims to aid water managers and policy makers with a greater understanding of transformational farmer adaptation in order to plan for the economic, social and health impacts of future water scarcity from climate change and water reform-related policies. The focus will be on the Murray-Darling Basin, as well as undertaking a comparative analysis with water stressed basins in the United States.Read moreRead less
Upland swamps and chains-of-ponds as unique and rare Australian river types: understanding their function to improve conservation and rehabilitation. Upland swamps and chains-of-ponds are nationally listed endangered ecosystems. They regulate water supply and quality in catchments. This project will deliver science on the physical and ecological function of these systems so conservation and rehabilitation initiatives within catchment action plans are effectively designed and implemented.
The actor and institutional dynamics in emerging socio-technical transitions. The project addresses the translation of environmental resource policies to widespread practice in the face of institutional inertia. The outcome informs the design of policy mechanisms for enabling the emergence and mainstreaming of alternative resource technologies and consolidates Australia's leadership in urban water resource management.
Cross-cultural management of freshwater on resource-constrained islands. This project aims to develop a methodology for community-led adaptive water management on resource-constrained islands and will involve Indigenous communities in the development of predictive groundwater models. The project plans to apply three-dimensional participatory mapping, a stakeholder engagement process led and owned by the local communities, on Milingimbi Island in the Northern Territory.

This project aims to develop a methodology for community-led adaptive water management on resource-constrained islands and will involve Indigenous communities in the development of predictive groundwater models. The project plans to apply three-dimensional participatory mapping, a stakeholder engagement process led and owned by the local communities, on Milingimbi Island in the Northern Territory. The extension of the participatory mapping with a subsurface component will then support the conceptualisation and development of a numerical model of the island's groundwater system. The predictive model and community engagement processes are expected to provide a more robust methodology for evaluating future water management plans. The project outcomes will contribute to solving water supply problems in remote communities in Australia, and overseas.Read moreRead less
Designing effective fish-friendly waterway culverts: integration of hydrodynamics and swimming performance. Man-made in-stream structures (for example, dams and road crossings) have contributed to major declines in native fish numbers, with more than 6,000 barriers to fish migration occurring in New South Wales alone. Recognising this, Fisheries New South Wales led the development of national guidelines for the design and construction of fish friendly road crossings. Unfortunately, these guideli ....Designing effective fish-friendly waterway culverts: integration of hydrodynamics and swimming performance. Man-made in-stream structures (for example, dams and road crossings) have contributed to major declines in native fish numbers, with more than 6,000 barriers to fish migration occurring in New South Wales alone. Recognising this, Fisheries New South Wales led the development of national guidelines for the design and construction of fish friendly road crossings. Unfortunately, these guidelines have little empirical backing. This project will integrate data on the swimming ability of Australian fish species with culvert hydrodynamic modelling to better understand fish requirements in and around road crossings. These data will strengthen national design guidelines and provide the tools engineers and planners need to balance fish migration with effective water management.Read moreRead less
