Uncertainty quantification in terrestrial hydrologic systems. This project aims to develop a framework to simulate, quantify and analyse the uncertainty in streamflow and vegetation dynamics via approximate Bayesian computation. Water is a fundamental resource, and a difficulty in water resource management is to make predictions in a changing environment. Uncertainties in predictions of natural systems due to observational and model error make this more difficult. It is anticipated that the resu ....Uncertainty quantification in terrestrial hydrologic systems. This project aims to develop a framework to simulate, quantify and analyse the uncertainty in streamflow and vegetation dynamics via approximate Bayesian computation. Water is a fundamental resource, and a difficulty in water resource management is to make predictions in a changing environment. Uncertainties in predictions of natural systems due to observational and model error make this more difficult. It is anticipated that the results from this project will advance uncertainty analysis in hydrology and help understand how different types of data and information can inform model characterisation. This will be useful in providing vital information on the attributes and extent of uncertainty to inform water resources analysis, management and decision making.Read moreRead less
Rupture: nature-society transformations in mainland Southeast Asia. This project aims to understand the nexus between intense, cumulative processes of socio-ecological change and emerging forms of social agency. Three case studies of Cambodian and Vietnamese dams, and a review of Thai-Lao cases, will reveal local and civil society responses to nature-society rupture and how these responses affect the region, inform advances in environmental change management, and be relevant to Australia's secur ....Rupture: nature-society transformations in mainland Southeast Asia.

Project outcomes will provide significant benefits for Australian responses to declining social and environmental safeguards occurring in the region.Read moreRead less
Optimal trade-offs for managing environmental water in inland wetlands. This project aims to optimise long-term water trade-offs in inland wetlands on managed catchments, without compromising their environmental value. These managed wetlands compete for water allocations with irrigation and other uses. Realistic predictions of wetland status will be achieved through the development and integration of an ecohydrological model and a water management decisions model. Application of the tools will i ....Optimal trade-offs for managing environmental water in inland wetlands. This project aims to optimise long-term water trade-offs in inland wetlands on managed catchments, without compromising their environmental value. These managed wetlands compete for water allocations with irrigation and other uses. Realistic predictions of wetland status will be achieved through the development and integration of an ecohydrological model and a water management decisions model. Application of the tools will improve existing decision support models to help analyse the effects of individual local management decisions on the long-term evolution of the system and the effects of changes in operation policies and climate over the long term. The project will provide critical new information for the improved prediction of wetlands evolution and as a consequence better management.Read moreRead less
Robust streamflow predictions by improving the identification of hydrological model structure.

A Paradigm Shift in the Hydrodynamics of Ion Flotation. Ion flotation has delivered remarkable separations via high selectivity, recovery and concentration upgrade. Yet, the technology has not provided solutions that are economically viable. This new project, however, aims to deliver the paradigm shift required in the flotation hydrodynamics to finally permit ion flotation to be applied to a broad range of industrial problems. Specifically, the aim is to increase extraction rates by more than an ....A Paradigm Shift in the Hydrodynamics of Ion Flotation. Ion flotation has delivered remarkable separations via high selectivity, recovery and concentration upgrade. Yet, the technology has not provided solutions that are economically viable. This new project, however, aims to deliver the paradigm shift required in the flotation hydrodynamics to finally permit ion flotation to be applied to a broad range of industrial problems. Specifically, the aim is to increase extraction rates by more than an order of magnitude by dramatically increasing bubble-liquid segregation rates, and bubble-surface fluxes. In turn the project is expected to develop a new line of solutions to industrial problems in hydrometallurgy for recovering precious metals and for solving toxic environmental problems.Read moreRead less
Dynamics of Suppressed Mixing Regimes in Australian Rivers. This study aims to further the fundamental science of turbulent mixing in the context of flow in Australian rivers. The focus is on prolonged low flow conditions which when coupled with warm surface temperatures cause the water column to become thermally stratified which then suppresses turbulent mixing. The extreme scale of the river systems has made investigating the true dynamics of the strongly stratified mixing regimes particularly ....Dynamics of Suppressed Mixing Regimes in Australian Rivers. This study aims to further the fundamental science of turbulent mixing in the context of flow in Australian rivers. The focus is on prolonged low flow conditions which when coupled with warm surface temperatures cause the water column to become thermally stratified which then suppresses turbulent mixing. The extreme scale of the river systems has made investigating the true dynamics of the strongly stratified mixing regimes particularly challenging. By taking world first in-situ measurements of turbulent mixing and undertaking high resolution numerical simulations this study will provide definitive data which will allow correct characterization of the mixing regimes and how they are associated with river flow conditions.Read moreRead less
The Mineral factor: strategic minerals, imperial resources and global politics (1895-1995). With the emergence of Asia, the political control of 'rare earths' vital to high-tech industries has prompted international diplomatic and commercial concern. This project explores the history of 'strategic minerals' and assesses the role of minerals policy in achieving both 'mineral security' and environmental sustainability.
A Fourier approach to address low-frequency variability bias in hydrology. This project aims to develop a mathematical framework to better simulate the occurrence of sustained anomalies, such as droughts and long periods of flooding, into the future. These events increase water insecurity and result in loss of revenue, livelihoods and lives. Hydrological planning requires knowledge of how such sustained extremes will change in the future. Current alternatives for simulating such changes for futu ....A Fourier approach to address low-frequency variability bias in hydrology. This project aims to develop a mathematical framework to better simulate the occurrence of sustained anomalies, such as droughts and long periods of flooding, into the future. These events increase water insecurity and result in loss of revenue, livelihoods and lives. Hydrological planning requires knowledge of how such sustained extremes will change in the future. Current alternatives for simulating such changes for future climates are inadequate for catchment-scale planning to proceed. The project proposes a strategy for post-processing hydrological simulations of the future using an elegant frequency-domain approach. It expects to provide the tools needed to develop hydrologic infrastructure, such as water supply reservoirs, that secure our water resources for the generations to come.Read moreRead less
