Urban subsurface flow pathways from stormwater infiltration. This project aims to understand how water (and associated pollutants) move through the urban landscape. Urban stormwater runoff degrades streams, causing erosion, pollution and loss of biodiversity. Stormwater infiltration can reduce runoff volumes and pollutant loads and could restore stream baseflows, lost through creation of impervious areas. In reality, however, the fate of infiltrated stormwater in the urban landscape is unknown. ....Urban subsurface flow pathways from stormwater infiltration. This project aims to understand how water (and associated pollutants) move through the urban landscape. Urban stormwater runoff degrades streams, causing erosion, pollution and loss of biodiversity. Stormwater infiltration can reduce runoff volumes and pollutant loads and could restore stream baseflows, lost through creation of impervious areas. In reality, however, the fate of infiltrated stormwater in the urban landscape is unknown. This project is expected to predict where infiltration may damage waterway health, saving money on repairs.Read moreRead less
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
A robust integrated streamflow forecasting framework for Australian water information and management agencies. This project aims to deliver an accurate and reliable seasonal streamflow forecasting system for Australian water users by developing a flexible rainfall-runoff modelling approach integrated into a Bayesian inference and prediction framework. These scientific developments aim to significantly advance the operational capabilities of the Australian Bureau of Meteorology to deliver robust ....A robust integrated streamflow forecasting framework for Australian water information and management agencies. This project aims to deliver an accurate and reliable seasonal streamflow forecasting system for Australian water users by developing a flexible rainfall-runoff modelling approach integrated into a Bayesian inference and prediction framework. These scientific developments aim to significantly advance the operational capabilities of the Australian Bureau of Meteorology to deliver robust streamflow forecasts to water agencies such as South East Queensland Water and others across Australia. Accurate predictions of future water flows are of tremendous value to urban and rural Australian communities whose economic prosperity, water security and social well-being depend on reliable estimates of water availability.Read moreRead less
Delivering robust hydrological predictions for Australia’s water challenges. This project aims to build a virtual hydrological laboratory to identify the best hydrological models that maximise predictive performance in a range of catchments, accounting for their dominant hydrological processes and data availability. New process-informed hydrological model structures will be developed using this virtual laboratory to embody our best understanding of hydrological processes and data from real catch ....Delivering robust hydrological predictions for Australia’s water challenges. This project aims to build a virtual hydrological laboratory to identify the best hydrological models that maximise predictive performance in a range of catchments, accounting for their dominant hydrological processes and data availability. New process-informed hydrological model structures will be developed using this virtual laboratory to embody our best understanding of hydrological processes and data from real catchments. The expected outcomes include major improvements in hydrological predictions for Australian catchments. This project will provide major benefits to irrigators, water authorities and engineers, who rely on hydrological predictions for sustainable water management in the highly-variable, semi-arid Australian climate.Read moreRead less
Catchment-scale and riparian zone stormwater retention: can it restore stream hydrology? This project will test whether or not stormwater retention systems dispersed throughout a catchment can restore pre-development streamflows in peri-urban streams. It will provide a new model for the design of stormwater drainage systems which both protect aquatic ecosystems and reduce the demand for imported water in cities.
Restoration trajectories of stream ecosystems degraded by urban stormwater runoff: a large-scale experiment in urban hydrology and stream ecology. This project aims to assess innovative dispersed stormwater retention systems in catchments for protection and restoration of urban streams. It will improve the ecological condition of several study streams and provide scientific support for new policies and practices for urban water management, with multiple environmental and community benefits.
Optimum design of hydraulic structures in rural and urban Australia: dealing with floods and droughts. Australia's long-term forecast suggests the occurrence of longer and more frequent droughts, and more intense flood events. The project will study the fundamental hydrodynamic processes in hydraulic structures and aims to develop new innovative designs derived from process based approach for optimum operation in rural and urban Australia.
