A new paradigm for catchment management: detection, forecasting and management of water catchments with multiple steady states. Understanding the response and recovery of Australia's water catchments to climatic change and variability is become increasingly urgent. Our catchments are vulnerable because there is a fundamental gap in our understanding of how they recover from high or low rainfall periods. This project will: a) advance water management concepts; b) build tools to understand how and ....A new paradigm for catchment management: detection, forecasting and management of water catchments with multiple steady states. Understanding the response and recovery of Australia's water catchments to climatic change and variability is become increasingly urgent. Our catchments are vulnerable because there is a fundamental gap in our understanding of how they recover from high or low rainfall periods. This project will: a) advance water management concepts; b) build tools to understand how and when catchments might switch to new states when hit by a disturbance; and c) identify how best to build the buffering capacity to reduce the chance of a switch occurring. The project will make Australia's groundwater and streamflow resources more secure and make Australian researchers and water resource managers world leaders in the emerging science of catchment resilience.Read moreRead less
Improving understanding of climate change and its impacts in Australia through detection and attribution of climate change. This research will quantify the contribution to Australian regional climate change due to greenhouse gases, which will assist policymakers in reaching decisions about policies on emission reductions or adaptation to greenhouse climate change. Improved estimates of uncertainties in future regional climate changes due to increasing greenhouse gases will allow better quantifi ....Improving understanding of climate change and its impacts in Australia through detection and attribution of climate change. This research will quantify the contribution to Australian regional climate change due to greenhouse gases, which will assist policymakers in reaching decisions about policies on emission reductions or adaptation to greenhouse climate change. Improved estimates of uncertainties in future regional climate changes due to increasing greenhouse gases will allow better quantification of their likely impacts, estimation of the costs or maximising any benefits from regional climate changes. Through collaboration with the Bureau of Meteorology and CSIRO, this research enhances Australia's capabilities in diagnostic analysis of climate variability and change, and aids the development and evaluation of new Australian climate models.

Understanding and modelling of interannual hydroclimatic variability in the context of historic streamflow. Recent persistently dry conditions in Australia have triggered water restrictions in major cities and re-emphasised the importance of water to this country. This project represents an integrated package of research that will enhance our understanding of interannual hydroclimatic variability, and its implications for land and water resources systems. The methodologies and model developed he ....Understanding and modelling of interannual hydroclimatic variability in the context of historic streamflow. Recent persistently dry conditions in Australia have triggered water restrictions in major cities and re-emphasised the importance of water to this country. This project represents an integrated package of research that will enhance our understanding of interannual hydroclimatic variability, and its implications for land and water resources systems. The methodologies and model developed here will directly lead to more informed decision making for sustainable use and management of Australia's increasingly scarce natural resources to cope with changing climate over a range of time scales. This is particularly important for Australia because of its higher interannual hydroclimate variability compared to elsewhere in the world.Read moreRead less
Narrowing the scatter and assessing the uncertainty of climate change projections of Australian river flows. Recent prolonged dry conditions in south-eastern Australia have triggered water restrictions in major cities, zero irrigation allocations in the Murray-Darling region and highlighted the importance of water to this country. This project represents an integrated package of research that will enhance our understanding of the uncertainty of future annual river flows, leading to more informed ....Narrowing the scatter and assessing the uncertainty of climate change projections of Australian river flows. Recent prolonged dry conditions in south-eastern Australia have triggered water restrictions in major cities, zero irrigation allocations in the Murray-Darling region and highlighted the importance of water to this country. This project represents an integrated package of research that will enhance our understanding of the uncertainty of future annual river flows, leading to more informed decision making for the sustainable management of Australia’s increasingly scarce water resources. The outcomes from this project are highly relevant to the national research priority “An Environmentally Sustainable Australia”, particularly priority goals “Water - a critical resource” and “Responding to climate change and variability”.Read moreRead less
Understanding the effect of climate change on runoff variability and water resource systems performance. This project aims to assess the impacts of climate changes on annual runoff variability. Understanding variability of annual runoff is important in managing water resources, in catchment and stream management, and to researchers in hydrology, stream ecology and fluvial geomorphology. Expected outcomes from this research are an estimate of impact on the variability of annual runoff from futu ....Understanding the effect of climate change on runoff variability and water resource systems performance. This project aims to assess the impacts of climate changes on annual runoff variability. Understanding variability of annual runoff is important in managing water resources, in catchment and stream management, and to researchers in hydrology, stream ecology and fluvial geomorphology. Expected outcomes from this research are an estimate of impact on the variability of annual runoff from future climate change, improvement in understanding the processes that operate on the variability of annual runoff, and an assessment of the performance of water resource systems under a changing climate.Read moreRead less
