Spatial and temporal monitoring of soil erosion risk with satellite imagery. This project is directed towards Sustainable farm practices, one of the national priorities in the Caring for Our Country program. The satellite image-based monitoring system will provide new information about the changing distribution of erosion risk in seasonal cropping systems, and identify areas where agricultural practices significantly influence this risk.

This project is directed towards Sustainable farm practices, one of the national priorities in the Caring for Our Country program. The satellite image-based monitoring system will provide new information about the changing distribution of erosion risk in seasonal cropping systems, and identify areas where agricultural practices significantly influence this risk. The research will allow landholders, regional, state and national authorities to better target effort towards sustainable land management, and improve monitoring and reporting of land condition across broad agricultural regions. Dynamic monitoring of erosion risk will also track landscape conditions and farmer responses to changing climate.Read moreRead less
Impact of recycled and low quality process water on sustainable mineral processing practices. Water is in short supply and needs to be considered as a 'key reagent'. The quality of this reagent can vary widely. For a sustainable mineral processing practice, the use of recycled or low quality/saline process water will be essential for a plant to operate in the future. The major benefit is recognition that significant recycle of process water for flotation is achievable if simple water quality con ....Impact of recycled and low quality process water on sustainable mineral processing practices. Water is in short supply and needs to be considered as a 'key reagent'. The quality of this reagent can vary widely. For a sustainable mineral processing practice, the use of recycled or low quality/saline process water will be essential for a plant to operate in the future. The major benefit is recognition that significant recycle of process water for flotation is achievable if simple water quality control and management practices are implemented. In addition, a better understanding and control of water quality in recycled/saline process water may lead to improved flotation stability and performance, and reduced reagent consumption.Read moreRead less
Improving flow management for the control of blue-green algal blooms. Cyanobacterial (blue-green algal) blooms are a major water quality problem worldwide. They are toxic, produce odours and are estimated to cost around $200 million/year in Australia alone. Flow management is one of the most promising approaches for combating the cyanobacterial bloom problem in rivers. In this research, a new risk-based approach for quantifying the impact of flow management on cyanobacterial blooms is developed, ....Improving flow management for the control of blue-green algal blooms. Cyanobacterial (blue-green algal) blooms are a major water quality problem worldwide. They are toxic, produce odours and are estimated to cost around $200 million/year in Australia alone. Flow management is one of the most promising approaches for combating the cyanobacterial bloom problem in rivers. In this research, a new risk-based approach for quantifying the impact of flow management on cyanobacterial blooms is developed, which can be applied to rivers world wide. The utility of the approach is demonstrated for key sites in the Murray-Darling basin, providing a valuable decision support tool for river managers.Read moreRead less
Setting Geographic Priorities for Integrated Landscape Restoration in a Fragmented Agricultural Region. This research project aims to develop the theory and application of integrated landscape restoration in a fragmented agricultural region - the Mt. Lofty Ranges of South Australia. Spatially explicit priorities will be set for the type and location of habitat to be restored for the benefit of the natural biodiversity within a physical environmental, economic and social context. Heuristic and op ....Setting Geographic Priorities for Integrated Landscape Restoration in a Fragmented Agricultural Region. This research project aims to develop the theory and application of integrated landscape restoration in a fragmented agricultural region - the Mt. Lofty Ranges of South Australia. Spatially explicit priorities will be set for the type and location of habitat to be restored for the benefit of the natural biodiversity within a physical environmental, economic and social context. Heuristic and optimisation models will be created within a Geographic Information System (GIS) and assessed for their ability to set such priorities in integrated landscape restoration. The techniques will help sustain ecological, physical and human systems in many other over-cleared regions.Read moreRead less
The ARC Earth System Science Research Network. The ARC Earth System Science Network incorporates data collectors, modellers and impacts researchers to address the impacts of climate change and variability on Human, biological and physical systems. Our capacity to adapt to changes in water availability, agricultural productivity, the likelihood of species extinctions, and risks to human health will be enhanced through the Network's use of frontier technologies.

The ARC Earth System Science Network incorporates data collectors, modellers and impacts researchers to address the impacts of climate change and variability on Human, biological and physical systems. Our capacity to adapt to changes in water availability, agricultural productivity, the likelihood of species extinctions, and risks to human health will be enhanced through the Network's use of frontier technologies. The enhanced capacity to use data and model the Earth System will allow policymakers to make more informed decisions with regard to water, biodiversity, human health, industry and agriculture sustainability; thereby enhancing the national capacity to respond to climate change and variability and securing our common interest.Read moreRead less
Control Of Aggregate Structure, Settling And Dewatering In Mineral Tailings Processing. Modification of aggregate structures in mineral processing will lead to improved dewatering in tailings operations. In mine site rehabilitation and tailings utilisation, technology developed in this project may save not only millions of dollars in more efficient processing and tailing deposition but also help to better reuse our limited national water resources.
Adaptive Agents Simulation of Freshwater Ecosystems: Artificial Intelligence Framework to Discover and Forecast Emergent Ecosystem Structures and Behaviours in Response to Environmental Changes. The project aims at intelligent adaptive agent models for lakes and rivers in order to improve understanding and proactive management of these highly complex ecosystems.

The project aims at intelligent adaptive agent models for lakes and rivers in order to improve understanding and proactive management of these highly complex ecosystems. Little is known about species succession in freshwater ecosystems in response to local and global environmental changes. Evolutionary algorithms embodied in differential equations, neural networks and rules allow adaptive agents to simulate emergent structures and behaviours of algae and zooplankton communities interacting by competition and predation. The agents are trained and tested by ecological time-series of twelve lakes and rivers, and validated for the Mediterranean Myponga Reservoir, South Australia, and the temperate Burrinjuck Reservoir, NSW.Read moreRead less
New Techniques for Artificial Neural Network Modelling in Hydrology. In recent years, artificial neural networks (ANNs) have demonstrated the potential to provide improved predictions when compared with the more traditional hydrological modelling techniques in a number of areas. These include the prediction of rainfall, streamflow and water quality parameters. However, one of the major difficulties associated with the application of ANNs is the lack of an established methodology for their design ....New Techniques for Artificial Neural Network Modelling in Hydrology.

These include the prediction of rainfall, streamflow and water quality parameters. However, one of the major difficulties associated with the application of ANNs is the lack of an established methodology for their design and implementation. This research will develop new methods for constructing ANN models and test them on a number of case studies so that the full potential and genuine utility of ANNs for solving hydrological problems can be assessed.Read moreRead less
