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
Sustainability of aquifer storage and recovery: the effects of nutrient load and water quality on aquifer clogging. Aquifer storage and recovery, ASR, stores excess water or treated effluent for subsequent beneficial use. Microbial and geochemical reactions can through clogging reduce aquifer permeability, increase pumping cost and may threatened the sustainability of the system. The relationships between injectant composition and biological geochemical clogging are poorly understood. Expanding ....Sustainability of aquifer storage and recovery: the effects of nutrient load and water quality on aquifer clogging. Aquifer storage and recovery, ASR, stores excess water or treated effluent for subsequent beneficial use. Microbial and geochemical reactions can through clogging reduce aquifer permeability, increase pumping cost and may threatened the sustainability of the system. The relationships between injectant composition and biological geochemical clogging are poorly understood. Expanding on prior field and column studies and techniques this project will study geochemical and microbial processes at on well-instrumented ASR trial site in South Australia. The relationship between effluent composition and change in hydraulic conductivity will be quantified, with a view to developping generic, practical decision-support tools and improve predictive model.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. However, groundwater samples are inevitably mixtures of water of different ages.

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

Accelerating Consolidation and Closure of Mine Tailings Storage Facilities. All mining operations involve the production of waste. Many regard such waste (tailings) and their environmentally acceptable storage as constituting the largest waste problem on Earth because of the enormous damage and loss-of-life that have resulted from failures of tailings storage facilities.

All mining operations involve the production of waste. Many regard such waste (tailings) and their environmentally acceptable storage as constituting the largest waste problem on Earth because of the enormous damage and loss-of-life that have resulted from failures of tailings storage facilities. This project focuses on a dewatering technology, electro-osmosis (EO), which has yet to be fully operationalised, for improving the strength, stability and settlement characteristics of the tailings. Sophisticated testing will be undertaken at three scales (lab, meso and, most importantly, field), as well as the development of generic numerical models, to create practical guidelines to facilitate the implementation of EO in mines around the world.Read moreRead less
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

An integrated modelling approach for efficient management of irrigated landscapes. Northern Victoria's irrigators use a substantial portion of water from the Murray-Darling Basin, which is under mounting pressure to satisfy competing economic, social and environmental needs for water in the face of climate change. Up to 20 per cent of this water may be on-farm surface runoff and deep percolation, with poorly known spatial distributions. This project will provide reliable temporally and spatially ....An integrated modelling approach for efficient management of irrigated landscapes. Northern Victoria's irrigators use a substantial portion of water from the Murray-Darling Basin, which is under mounting pressure to satisfy competing economic, social and environmental needs for water in the face of climate change. Up to 20 per cent of this water may be on-farm surface runoff and deep percolation, with poorly known spatial distributions. This project will provide reliable temporally and spatially distributed information on surface runoff and deep percolation for Northern Victoria irrigation regions. This will inform decisions which improve water use efficiency, agricultural productivity and environmental values through optimisation of irrigation infrastructure and by better management of groundwater resources and salinity.Read moreRead less

Present review of water resources within catchments of the Murray-Darling Basin will result in reduced access to water for consumptive use with consequential significant socio-economic and community impacts. Water markets are seen as major instruments to assist farmers in managing this process and thereby minimize the impact within rural communities. However, research has identified several barriers to trade and several future research needs. This project addresses five of these issues by providing insight into three community barriers to trade as well as a framework for ongoing monitoring, analyses and reporting of market outcomes and impacts to assist adaptive policy development.Read moreRead less
