Chemical optimisation of geothermal heat extraction. Geothermal energy can contribute to our energy needs, but we must understand chemical interactions between geothermal fluids, the host aquifers and the engineered environment to use the energy safely and efficiently. This project will assess those interactions, provide guidelines for geothermal energy use and train future geothermal scientists.
Ecological regime shifts for re-engineering water pollution management. This project aims to validate a framework for the management of water pollution. As the world population increases, maintaining robust, cost-effective and environmentally safe water resources is important. This project will investigate environmental controls of toxin occurrence in urban and wastewater systems. The project is expected to mitigate deadly cyanotoxins, which threaten the safety of water resources, while a numeri ....Ecological regime shifts for re-engineering water pollution management.

The project is expected to mitigate deadly cyanotoxins, which threaten the safety of water resources, while a numerical ecological model will tackle water pollution issues in natural and engineered water systems.Read moreRead less
Catchment water balance and CO2 fluxes: a comparison between productive land uses. The aim of the project is to improve the understanding of different land use implications on water resource and land productivity. The project aims to use a paired-catchment study that compares the carbon and water balances in two catchments in the high rainfall zone in south western Victoria. One catchment is used prevalently for grazing, while the other is predominantly planted with blue gums. The main objective ....Catchment water balance and CO2 fluxes: a comparison between productive land uses. The aim of the project is to improve the understanding of different land use implications on water resource and land productivity. The project aims to use a paired-catchment study that compares the carbon and water balances in two catchments in the high rainfall zone in south western Victoria. One catchment is used prevalently for grazing, while the other is predominantly planted with blue gums. The main objectives of this project are: to quantify the effect of different agricultural land uses on the catchment water balance; to estimate the trade-off between carbon sequestration and water resources related to tree plantations and pastures; and to develop models at different spatial scales of catchment water balance for land-use management.Read moreRead less
A unified approach for estimating coastal flood risk. The project aims to develop a unified approach to quantifying flood risk. Because flooding is caused by multiple mechanisms such as extreme rainfall, storm surge and astronomical tide, accurately estimating flood levels in the Australian coastal zone is challenging. By quantifying flood risk in terms of these mechanisms, the project is expected to provide reliable flood risk estimates for both historical settings and future climate scenarios. ....A unified approach for estimating coastal flood risk.

By quantifying flood risk in terms of these mechanisms, the project is expected to provide reliable flood risk estimates for both historical settings and future climate scenarios. The improved estimation should enable Australian water agencies and policy-makers to effectively design defence infrastructure (e.g. drainage systems) and urban planning policies to adapt to future flood risk.Read moreRead less
Improving airborne electromagnetic surveying for minerals and groundwater. Groundwater is vital in many parts of Australia due to low surface water availability while much of Australia’s mineral wealth is obscured by conductive cover. Airborne surveys are key to mapping minerals and water over large areas.

Groundwater is vital in many parts of Australia due to low surface water availability while much of Australia’s mineral wealth is obscured by conductive cover. Airborne surveys are key to mapping minerals and water over large areas. This project aims to enhance the resolution of airborne electromagnetic surveying technology by developing advanced new aircraft transmitters and receivers. The project expects to enable complex groundwater structures to be mapped more accurately and increase the depth to which conductive ore bodies can be detected. Expected outcomes include the discovery of new economic mineral and water resources. This should provide significant benefits to the mining and agricultural industries.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. This project focuses on a dewatering technology, electro-osmosis (EO), which has yet to be fully operationalised, for improvin ....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. 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
Turbulent vertical mixing in stratified flows. The project will provide the first definitive data set to document, at the process level, the contribution of turbulance, to mixing in stratified flows and improve our understanding of how well current closure schemes mimic the buoyancy flux and the Reynolds stresses in a stratified shear flow.
Mobile foundations: shifting paradigms in deep sea engineering. The project will generate a paradigm shift in the approach to foundation design for deepwater hydrocarbon facilities through the innovation of mobile foundations – meaning foundations that are designed to move tolerably to accommodate displacements rather than remain stationary and resist loads. Experimental, numerical and theoretical modelling will create a new understanding of mobile foundation-seabed interaction unlocking solutio ....Mobile foundations: shifting paradigms in deep sea engineering. The project will generate a paradigm shift in the approach to foundation design for deepwater hydrocarbon facilities through the innovation of mobile foundations – meaning foundations that are designed to move tolerably to accommodate displacements rather than remain stationary and resist loads. Experimental, numerical and theoretical modelling will create a new understanding of mobile foundation-seabed interaction unlocking solutions to assess the tolerability of foundation mobility though a facility life cycle. Mobile foundations will offer a more economic and reliable basis to support subsea infrastructure, making safer and more viable the development of Australia’s deepwater reserves that are currently ‘stranded’.Read moreRead less

There is a degree of public anxiety on how unconventional gases is extracted. Horizontal drilling and hydraulic fracturing are two key enabling technologies to extract unconventional gases. But, the current study reveals well and field productivities exhibit steep declines. This implies that current practice may not be sustainable. The successful completion of this project will provide a scientific approach to look at the sustainability issue through testing a hypothesis that the properties of rock blocks between hydraulic fractures determine the sustainability of gas production instead of hydraulic fracturing.
