More bang for your carbon buck: carbon, biodiversity and water balance consequences of whole-catchment carbon farming. Farming carbon via tree plantings on pasture land is becoming increasingly common to address the effects of climate change. This activity is likely to produce dramatic changes in Australia's rural landscapes, but we have little knowledge of likely effects on crucial ecosystem services and attributes such as stream water yields and biodiversity. This project will investigate the ....More bang for your carbon buck: carbon, biodiversity and water balance consequences of whole-catchment carbon farming. Farming carbon via tree plantings on pasture land is becoming increasingly common to address the effects of climate change. This activity is likely to produce dramatic changes in Australia's rural landscapes, but we have little knowledge of likely effects on crucial ecosystem services and attributes such as stream water yields and biodiversity. This project will investigate the relationship between tree cover, carbon uptake, water yield and biodiversity. The outcomes will allow government agencies, landowners and carbon farming groups to better evaluate the effects of different landscape planning options and contribute to effective long-term planning for multiple goals.Read moreRead less
Observed streamflow generation changes: better understanding and modelling. This Project aims to investigate drivers and triggers of variable streamflow response during and after drought and develop modelling strategies and model structures more robust to changing streamflow response. In many catchments during the Millennium Drought, streamflow generation was less than expected and hydrologic models performed poorly. After the drought, streamflow generation is yet to recover in some catchments. ....Observed streamflow generation changes: better understanding and modelling. This Project aims to investigate drivers and triggers of variable streamflow response during and after drought and develop modelling strategies and model structures more robust to changing streamflow response. In many catchments during the Millennium Drought, streamflow generation was less than expected and hydrologic models performed poorly. After the drought, streamflow generation is yet to recover in some catchments. This Project expects to generate new knowledge about variable streamflow response to drought and develop strategies and models to robustly simulate runoff during and after changed conditions, which should provide significant benefit via better understanding and modelling of streamflow response under changing conditions.Read moreRead less
Vulnerabilities for environmental water outcomes in a changing climate. This project aims to assess the vulnerability of freshwater ecosystems to extended droughts in a variable and changing climate. Governments around the world are investing in the restoration of regulated river systems with environmental water. However, the risks of climate change for environmental water management are seldom considered. This project will model the change in environmental and consumptive water use during exten ....Vulnerabilities for environmental water outcomes in a changing climate. This project aims to assess the vulnerability of freshwater ecosystems to extended droughts in a variable and changing climate. Governments around the world are investing in the restoration of regulated river systems with environmental water. However, the risks of climate change for environmental water management are seldom considered. This project will model the change in environmental and consumptive water use during extended dry periods, and couple this to models of ecological dynamics and failure thresholds. This will improve the success of Australia’s major environmental water programs in sustaining benefits through future multi-year droughts.Read moreRead less
Optimisation of catchment management: stable isotope studies of water storage and yield. Focusing on the Cotter catchment, this project will establish how the water content of soils and tree stems regulates the amount of water used by trees in sub-catchments, and thus how much reaches streams and dams. Small areas supply most of the water yield and this project will help identify where managers should focus efforts to increase yield.
Paving the way to greener roads and healthier waterways. Waste tyre permeable pavement is emerging as an effective stormwater surge mitigation solution. Yet, its behaviour under traffic loads and varied environmental conditions are not fully understood which undermines industry confidence in this technology. This project aims to advance the engineering of waste tyre permeable pavements by creating new knowledge on their mechanical and hydrological performance. The project will develop design gui ....Paving the way to greener roads and healthier waterways. Waste tyre permeable pavement is emerging as an effective stormwater surge mitigation solution. Yet, its behaviour under traffic loads and varied environmental conditions are not fully understood which undermines industry confidence in this technology. This project aims to advance the engineering of waste tyre permeable pavements by creating new knowledge on their mechanical and hydrological performance. The project will develop design guidelines, identify the governing mechanisms and develop a performance prediction framework based on laboratory and field tests, and advanced numerical modelling. The mechanisms of performance from micro to macro level will be identified, generating knowledge for industry to support widespread uptake.Read moreRead less
Water availability and demand: better forecasts, better management. This project aims to improve Australia’s capability in the provision and use of water forecasts for managing water resources. The current water forecasts are not fully utilised by water agencies as they are not sufficiently comprehensive and advanced. This project expects to achieve a step change in the uptake and utility of hydro-climate forecasts through an extensive partnership of leading researchers and operational agencies ....Water availability and demand: better forecasts, better management. This project aims to improve Australia’s capability in the provision and use of water forecasts for managing water resources. The current water forecasts are not fully utilised by water agencies as they are not sufficiently comprehensive and advanced. This project expects to achieve a step change in the uptake and utility of hydro-climate forecasts through an extensive partnership of leading researchers and operational agencies of hydro-climate forecasting, with federal, state and regional water agencies.Read moreRead less
A decadal to inter-decadal streamflow prediction system. This project will develop the first ever decadal streamflow prediction system for Australia, leading to predictions of streamflow for the next 10 years and beyond that take into account both natural climatic variability (driven by factors such as the El Nino Southern Oscillation) and changing greenhouse gas concentrations due to a warming planet.
Megadrought likelihood and its water resource impacts in Australia. This interdisciplinary project plans to assemble a world-class team of hydrologists, climate scientists and water managers to investigate the history and future risk of decadal to multidecadal droughts (megadroughts). Despite Australia’s vulnerability to water scarcity, the likelihood of persistent megadroughts has not been assessed in Australia. This has resulted in inadequate capacity to prepare for and adapt to megadrought un ....Megadrought likelihood and its water resource impacts in Australia. This interdisciplinary project plans to assemble a world-class team of hydrologists, climate scientists and water managers to investigate the history and future risk of decadal to multidecadal droughts (megadroughts). Despite Australia’s vulnerability to water scarcity, the likelihood of persistent megadroughts has not been assessed in Australia. This has resulted in inadequate capacity to prepare for and adapt to megadrought under future climate change. For the first time, palaeoclimate reconstructions and climate change projections will be used to constrain future hydroclimatic variability, advancing the decision-making capacity of Australian water resource managers.Read moreRead less
A new-generation flood forecasting system using observations from space. Floods are dangerous and expensive, costing Australia more than any other cause of natural disaster. This project will use satellite measurements of soil moisture and rainfall along with computer models to improve the Bureau of Meteorology’s predictions of floods in rivers. Better flood forecasts will reduce costs and save lives.
