This project aims to resolve the complex interactions affecting the long-term performance of geosynthetic liner systems under harsh environmental conditions for preventing groundwater contamination. Failures of waste containment lining systems result in millions of dollars remedial costs and high societal costs. The project expects to underpin the development of an experimentally-validated theory to predict the performance of geosynthetic liner systems at high temperatures. Expected outcomes of the project are the establishment of a new conceptual framework and providing new guidelines for the design of geosynthetic liner systems for environmental protection. These outcomes are expected to benefit the waste and mining industries by informing planning, decision makers, consultants and construction engineers with science-based information on new lining systems for landfills and mining and industry waste containment.Read moreRead less

This project aims to overcome the scientific and technological challenges preventing soil water and vegetation forecasting at useful land management scales (eg. 25 m). The significance is in enabling an unprecedented hyperresolution modelling capability for Australia through the integration of new ecohydrological theory with a range of satellite observations. Outcomes include more accurate, spatially-detailed information of current soil water amounts, and reliable forecasts of vegetation condition several months into the future. This will greatly enhance timely decision making and forward planning by farmers, fire agencies, and other land and water managers, with corresponding increases in productivity, sustainability and community safety.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.

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
Carbon conundrum: Functional characterisation of organic matter-clay mineral interactions in relation to carbon sequestration. Carbon sequestration in soil has been recognised as one of the possible measures through which greenhouse gas emissions can be mitigated. The major processes involved in carbon sequestration in soil include chemical immobilisation of carbon with soil particles and physical protection in the pores of soil microaggregates. These two processes are mediated through the funct ....Carbon conundrum: Functional characterisation of organic matter-clay mineral interactions in relation to carbon sequestration. Carbon sequestration in soil has been recognised as one of the possible measures through which greenhouse gas emissions can be mitigated. The major processes involved in carbon sequestration in soil include chemical immobilisation of carbon with soil particles and physical protection in the pores of soil microaggregates. These two processes are mediated through the functional relationships of soil organic matter and clay mineral interactions in soils. This project investigates nanoscale organomineral association underlying microaggregate formation and stability, as well as the distribution and microbial decomposition of carbon within microaggregates using a suite of advanced spectroscopic, molecular and isotopic techniques.Read moreRead less
Realistic assessment of biomarker transformation in the wastewater system. Wastewater-based epidemiology is an internationally recognised cost-effective tool to monitor population exposure to chemicals and infectious diseases including Covid-19. However, in-sewer degradation of critical biomarkers can limit their wastewater-based epidemiology suitability.

Wastewater-based epidemiology is an internationally recognised cost-effective tool to monitor population exposure to chemicals and infectious diseases including Covid-19. However, in-sewer degradation of critical biomarkers can limit their wastewater-based epidemiology suitability. This project aims to systematically evaluate the stability of a new suite of potential biomarkers and conduct the first Australia-wide assessment on the impact of biomarker stability on wastewater-based epidemiology estimates using wastewater samples from ~65% of the Australian population. The project expects to generate knowledge to expand the application of wastewater-based epidemiology to reliably quantify exposure and status of well-being even in remote areasRead moreRead less
The key strategies in firms' realisation of value from ICT: A transformational model of ICT value generation. Studies indicate that information and communication technologies (ICT) have contributed significantly to Australia's productivity gains over the last decade. It is not well understood, however, why some firms and some industries have been able to benefit significantly more from ICT use than others.

Studies indicate that information and communication technologies (ICT) have contributed significantly to Australia's productivity gains over the last decade. It is not well understood, however, why some firms and some industries have been able to benefit significantly more from ICT use than others. This study will show the strategies and practices that are used by the firms that gain maximum benefit from ICT - the 'ICT winners'. The lessons learned will allow other firms to gain further benefits from ICT, potentially leading overall to further economic gains by industries and the nation. Read moreRead less
Classifying the indirect costs of information systems and information technology in business. Many businesses are increasing their expenditure on IS/IT to obtain a strategic competitive advantage. Traditional approaches to IS/IT appraisal are unable to accommodate the costs associated with deploying 'organisational-wide' IS/IT solutions because of their qualitative characteristics. The inability of managers to determine the 'true' costs of IS/IT are attributable to a lack of knowledge and unders ....Classifying the indirect costs of information systems and information technology in business. Many businesses are increasing their expenditure on IS/IT to obtain a strategic competitive advantage. Traditional approaches to IS/IT appraisal are unable to accommodate the costs associated with deploying 'organisational-wide' IS/IT solutions because of their qualitative characteristics. The inability of managers to determine the 'true' costs of IS/IT are attributable to a lack of knowledge and understanding of IS/IT related costs. This research will extend the myopia of traditional 'direct' financial cost analysis by identifying 'indirect' cost factors. A model that integrates cost taxonomies and performance measures/metrics of IS/IT will be developed as a frame of reference for IS/IT decision-makers.Read moreRead less

This project aims to investigate how environmental change and human activities since industrialisation have impacted toxic metal transport and deposition on the south coast of Australia, Tasmania and Southern Ocean islands. This project expects to fill gaps in understanding of the global mercury cycle using a state-of-the-art multidisciplinary methodology including the role of sea salt aerosols and hemispheric-scale wind patterns . Anticipated outcomes involve a novel palaeo-atmospheric model that can be applied in other parts of the world. This should provide significant benefits, such as science-based evidence to ratify the Minamata Convention on Mercury and guide new regulations to reduce environmental/health risks from metal pollution.
