To date, much of the process improvement for industrial application of membrane technology has revolved around polymer science based development of membrane materials and process and module changes resulting from the application of basic (often simplistic) engineering principles. While some future improvements may still come from these areas, the most dramatic advances are likely to be derived from the application of advanced engineering principles to this complex system. This project will integrate advanced CFD modelling and control principles for the design and operation of membrane systems in order to develop fundamental understanding that should lead to significant process improvements.Read moreRead less
Simulation Technology for Modelling Extreme Bushfire Behaviour. Extreme fires cause immeasurable damage to communities through destruction of homes and damage to infrastructure. Large, highly intense fires reduce biodiversity, take decades for recovery, increase greenhouse gas emissions and reduce carbon storage capacity. Climate change is likely to increase the frequency of extreme fire weather increasing the need for reliable fire spread prediction under extreme conditions and to reduce impa ....Simulation Technology for Modelling Extreme Bushfire Behaviour. Extreme fires cause immeasurable damage to communities through destruction of homes and damage to infrastructure. Large, highly intense fires reduce biodiversity, take decades for recovery, increase greenhouse gas emissions and reduce carbon storage capacity. Climate change is likely to increase the frequency of extreme fire weather increasing the need for reliable fire spread prediction under extreme conditions and to reduce impact by preparedness and suppression. Incorporating an evidence-based fire spread model into a fire location forecasting system will give fire agencies early warning of potentially disastrous fires, enable early response to prevent fires and mitigate the consequence to life, property and the environment.

Coupled Atmosphere-Bushfire Modelling with Application to Canberra 2003. Large bushfires are by far the largest contributor to property losses in Australia. Prescribed fire is an important land management tool for farmers, foresters and park managers among others. There is a need to develop practical and accurate tools for predicting the behaviour and spread of both prescribed and uncontrolled fires. Australian bushfire research and land management would benefit greatly from the application of m ....Coupled Atmosphere-Bushfire Modelling with Application to Canberra 2003. Large bushfires are by far the largest contributor to property losses in Australia. Prescribed fire is an important land management tool for farmers, foresters and park managers among others. There is a need to develop practical and accurate tools for predicting the behaviour and spread of both prescribed and uncontrolled fires. Australian bushfire research and land management would benefit greatly from the application of modern, advanced computational methods. The time is ripe for the huge advances in computer technology and numerical modelling to be applied directly to fire problems, benefiting public safety and the safety of fire-fighting volunteers.Read moreRead less
Integrated Water Management in the Lower Richmond Catchment. Water quality in Richmond River estuary, NSW, is of critical concern to fishing, aquaculture, tourism and recreation industries. Upland horticulture on the Alstonville Plateau and drained acid sulfate soils in lowland floodplains discharge nutrient-rich, acidic water to the estuary. Previous studies have treated floodplains, upland and estuary separately. This study will develop an integrated catchment approach to water management in t ....Integrated Water Management in the Lower Richmond Catchment. Water quality in Richmond River estuary, NSW, is of critical concern to fishing, aquaculture, tourism and recreation industries. Upland horticulture on the Alstonville Plateau and drained acid sulfate soils in lowland floodplains discharge nutrient-rich, acidic water to the estuary. Previous studies have treated floodplains, upland and estuary separately. This study will develop an integrated catchment approach to water management in the Lower Richmond by treating surface water and groundwater as a single resource. The whole-of-system approach will help mitigate socio-economic and environment impacts of nutrient-rich and acidic drainage waters. It will be transferable to other "hot spots" in Australia.Read moreRead less

Algorithms for change detection based on finite sample system identification theory. Detection of abrupt changes has many important applications. One particular application that will be investigated is leak detection in irrigation channels. As agriculture accounts for about 80% of Australia's water usage, the timely detection of leaks means that corrective actions can be taken early which will lead to large water savings and significant environmental benefits. The developed methods can be design ....Algorithms for change detection based on finite sample system identification theory. Detection of abrupt changes has many important applications. One particular application that will be investigated is leak detection in irrigation channels. As agriculture accounts for about 80% of Australia's water usage, the timely detection of leaks means that corrective actions can be taken early which will lead to large water savings and significant environmental benefits. The developed methods can be designed with any false alarm rate. This is important since frequent false alarms lead to wasted resources and operators will stop using the system. The technology once developed can be transferred to many other application areas such as urban water supplies, pipelines for oil and gas, and the process and manufacturing industries.Read moreRead less
