The two techniques to be developed and tested here will allow the measurement of the 3D density and velocity fields in lakes and estuaries using only simple instruments and with minimum lake obstruction. Coupled with a Real Time Management System, these techniques can be used to validate numerical models and to simulate scenarios, such as future flood events, which have the potential for contamination of water quality. The output from these simulations is then used, again in real time, to evaluate the new Index of Sustainable Functionality of the water body. When augmented with the results from this research we would have a tool that would help manage lakes and reservoirs to optimize the water quality, while maintaining the supply.Read moreRead less

This project will research and develop a full-scale effluent reuse wetland to manage acid sulfate soils, regenerate wetlands and sequester atmospheric carbon. Many rural communities worldwide are affected by acid sulfate soils, unsustainable effluent disposal and wetland degradation, and the Greenhouse Effect threatens all coastal areas worldwide. This project is located at Byron Bay, a coastal and predominantly rural electorate in northern NSW that is strongly affected by this combination of environmental stresses, causing serious degradation of water quality culminating in regular fish kills. The technology developed from this project will be readily transferable to other rural coastal communities worldwide.Read moreRead less
Conducting coatings for control and eradication of unwanted marine biofilms. Biofilms grow on all surfaces and environments posing environmental threats and economic issues globally, costing billions each year to those attempting to eradicate them.

The project aims at (i) developing novel electrically conducting carbon based paints that are stable in marine ....Conducting coatings for control and eradication of unwanted marine biofilms. Biofilms grow on all surfaces and environments posing environmental threats and economic issues globally, costing billions each year to those attempting to eradicate them. To date, biofilm's detailed response to variations in electrochemically generated redox stress and shear is unknown in marine environments. The project aims at (i) developing novel electrically conducting carbon based paints that are stable in marine environments and (ii) investigating how marine biofilms respond to these coatings. The expected outcome of this project is the development of a green alternative antifouling technology that can be used on demand in marine applications. This provides a new solution for controlling the biofouling of surfaces immersed in oceans.Read moreRead less

Growing concerns about sustainability issues with fossil fuels have resulted in strong interest in wind power worldwide. Grid-connected inverters are an efficient way of utilising small wind turbines on domestic, farming or small commercial properties which have access to the power grid. Existing small-scale, grid-connected wind turbines are expensive and have a limited operating wind speed range. We are investigating new designs for low-cost wind turbine generators which can produce power over a wide range of wind speeds. The project should result in a greater application of small-scale wind generators in Australia and will lead to reductions in fossil fuel usage and greenhouse gas emissions.Read moreRead less
