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. 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 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

Summary
Mobile weather radar system for advanced environmental monitoring and modelling. High spatial and temporal resolution weather radar data on wind and precipitation will translate to significant environmental model advances. Australian researchers will undertake model validation studies on precipitation, dust storm, and flood prediction under a wider range of environmental conditions and in greater detail than currently possible.
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
Mass flux pathways in stratified lakes. The aims of this project are to determine parametric descriptions of all transport and mixing mechanisms and their interactions in a stratified lake, validate these parameterisations through process fieldwork (Lake Argyle and Lake St Clair) and then use this understanding to validate and improve a new Lagrangian Dynamic Lake Multi-Basin Model. This project will endeavour to provide lake managers with a new, validated numerical model that will allow inter-s ....Mass flux pathways in stratified lakes. The aims of this project are to determine parametric descriptions of all transport and mixing mechanisms and their interactions in a stratified lake, validate these parameterisations through process fieldwork (Lake Argyle and Lake St Clair) and then use this understanding to validate and improve a new Lagrangian Dynamic Lake Multi-Basin Model. This project will endeavour to provide lake managers with a new, validated numerical model that will allow inter-seasonal simulations with the numerical error being less than the signal. This will be of great importance to ecology, as future advances in that area will largely depend upon a model with correct description of the mass flux paths in a stratified lake.Read moreRead less
Upscaling laws for hydraulic fracturing of tight formations using reproducible true tri-axial laboratory testing. Upscaling models for designing hydraulic fracture stimulation of gas reservoirs will be developed. Innovative laboratory methods of reproducing the field stress conditions and rock structure will be used. The results will advance the mechanics of hydraulic fracturing and increase efficiency of reservoir stimulation, especially in tight formations.
Fracture propagation through fragmented solids. This project investigates fracture propagation in heavily fractured (fragmented) solids such as rock masses, ice covers, fractured coatings, mortar-free structures. It introduces new ideas and methods and has potential to result in a breakthrough science to achieve better understanding of the fundamental processes of fracturing fragmented materials that will advance knowledge and develop technological innovations. A particular outcome of the projec ....Fracture propagation through fragmented solids. This project investigates fracture propagation in heavily fractured (fragmented) solids such as rock masses, ice covers, fractured coatings, mortar-free structures. It introduces new ideas and methods and has potential to result in a breakthrough science to achieve better understanding of the fundamental processes of fracturing fragmented materials that will advance knowledge and develop technological innovations. A particular outcome of the project will be in developing tools for designing new materials with enhanced failure resistance. Another application is in Resource Engineering and Earth and Planetary Science; the project will contribute to understanding of fracture propagation in the Earth's (and generally, planetary) crust.Read moreRead less
