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.
Research and development of devices to improve the quality of stormwater by removal of gross pollutants such as soil, litter and sediment. Oil,litter and sediment are serious pollutants in stormwater which go hand in hand with human and industrial activity. An outcome of this research will be to develop a device capable of removing such gross pollutants from stormwater at higher efficiencies than that currently commercially available. Vital wetland resources such as Moreton Bay near Brisbane, a ....Research and development of devices to improve the quality of stormwater by removal of gross pollutants such as soil, litter and sediment. Oil,litter and sediment are serious pollutants in stormwater which go hand in hand with human and industrial activity. An outcome of this research will be to develop a device capable of removing such gross pollutants from stormwater at higher efficiencies than that currently commercially available. Vital wetland resources such as Moreton Bay near Brisbane, a wetland of international significance that contributes around $400 million to the local economy,are under threat from polluted stormwater. Similar problems are occuring right around the entire coast of Australia and also in some inland waterways.Read moreRead less

This project plans to improve the monitoring of our waterways by developing a novel moving drifter system that takes flow and water quality measurements along the pathlines of the drifters. One of the key challenges for Australian water management lies in monitoring and managing rivers and estuaries effectively over large geographical areas. Traditionally, instrumentation at stationary points has been used for such monitoring, under the simplifying assumption that a single point adequately represents a very large region of water. By contrast, the Real-Time Flow Logging of Water (RT-FLOW) system expects to provide information from large regions of our waterways, providing stakeholders with more information to enable them to better manage issues including storm surge and erosion. The project also aims to provide improved validation of hydrodynamic models.Read moreRead less
