Could porous pavements be a part of the urban water solution? With water demand in Australia approaching, and sometimes exceeding, limits of sustainability, there is a pressing need to find alternative water sources. At the same time, urban stormwater pollution remains a major environmental threat. These problems are particularly difficult in urban areas, due to space constraints. This project will test and refine porous pavement technology, which could help solve the 'urban water problem'. R ....Could porous pavements be a part of the urban water solution? With water demand in Australia approaching, and sometimes exceeding, limits of sustainability, there is a pressing need to find alternative water sources. At the same time, urban stormwater pollution remains a major environmental threat. These problems are particularly difficult in urban areas, due to space constraints. This project will test and refine porous pavement technology, which could help solve the 'urban water problem'. Replacing impervious areas with porous pavements will allow urban stormwater to be treated and harvested for re-use. Waterways will be protected from pollution, and the vast quantity of urban stormwater generated (similar to the total reticulated water supplied in Australia) can be harvested to sustain cities.Read moreRead less

Summary
Advanced characterisation of organics and biopolymers in water and wastewater treatment. Although membrane technology is increasingly used for water production, wastewater treatment and reclamation, fouling by complex bio-organics is a major limitation. The liquid chromatography-organic carbon detection and the Flow FFF equipments give detailed analyses of the complex organics, thereby helping to understand the fouling and organic removal mechanisms allowing process optimisation. The availabilit ....Advanced characterisation of organics and biopolymers in water and wastewater treatment. Although membrane technology is increasingly used for water production, wastewater treatment and reclamation, fouling by complex bio-organics is a major limitation. The liquid chromatography-organic carbon detection and the Flow FFF equipments give detailed analyses of the complex organics, thereby helping to understand the fouling and organic removal mechanisms allowing process optimisation. The availability of these equipments will ramatically improve the quality of a number of research projects currently funded and being developed in Australia. This equipment would provide necessary infrastructure to keep Australian researchers world leaders in this research field (one of Australian top research priorities) and attract national and international collaborations.Read moreRead less

The Research Network for Engineering a Secure Australia (RNESA) is a multi-disciplinary collaboration established to strengthen Australia's science and technology capacity for protecting the Nation's critical infrastructure from natural or human-caused disasters. RNESA will facilitate a knowledge sharing network for government, universities and the private sector to produce innovative engineering solutions to the emerging security problems relating to the safety of critical infrastructure. This initiative will draw together researchers across disciplines to identify a roadmap for future R&D in this area. RNESA's final outcomes will lead to multi-hazard mitigation strategies and a real-time crisis support network to enable the nation to manage potential disasters.Read moreRead less
Evaluating the role of buffer strips in reducing soil erosion and sediment delivery to water bodies. The role of vegetative buffer strips in reducing soil erosion and sediment delivery to water bodies is well established, but the physical processes and their interactions involved are not well understood. These hydraulic, sediment/chemical transport processes will be modelled from physical principles, recognising that the multi-size characteristics of soil plays a vital role in buffer strip effec ....Evaluating the role of buffer strips in reducing soil erosion and sediment delivery to water bodies. The role of vegetative buffer strips in reducing soil erosion and sediment delivery to water bodies is well established, but the physical processes and their interactions involved are not well understood. These hydraulic, sediment/chemical transport processes will be modelled from physical principles, recognising that the multi-size characteristics of soil plays a vital role in buffer strip effectiveness. This model will be validated using new and existing data sources, including both controlled experiments and field data obtained in Australia and overseas. A user friendly version of the model will be developed for farm managers and advisory services as a design tool.Read moreRead less
Exposure dating with manganese-53, neon-21 and beryllium-10: a new toolkit for studying long-term landscape evolution. Australia today is the driest inhabited continent but this was not always the case. Tens of millions of years ago the climate of Australia was considerably wetter. Then, several million years ago, aridity in Australia developed producing most of the desert features of the red Centre that we see today. The age of our deserts and other arid features are not, however, well known.

Australia today is the driest inhabited continent but this was not always the case. Tens of millions of years ago the climate of Australia was considerably wetter. Then, several million years ago, aridity in Australia developed producing most of the desert features of the red Centre that we see today. The age of our deserts and other arid features are not, however, well known. This project will determine the age of desertification in Australia, thereby enhancing our understanding of such processes and the response of our landscape to changing climate.

Sediment stock-piling and the fate of Australian floodplains. Historic landuse practices have profoundly altered Australia's river systems in less than 200 years. Up to 80% of the sediment and associated pollutants eroded from Australia's catchments are stored in floodplains. The assumption that floodplains can continue to absorb the impacts of upland erosion and land degradation is extremely risky, yet it underpins current catchment management policies in Australia. This project delivers essent ....Sediment stock-piling and the fate of Australian floodplains. Historic landuse practices have profoundly altered Australia's river systems in less than 200 years. Up to 80% of the sediment and associated pollutants eroded from Australia's catchments are stored in floodplains. The assumption that floodplains can continue to absorb the impacts of upland erosion and land degradation is extremely risky, yet it underpins current catchment management policies in Australia. This project delivers essential data on floodplain storage and remobilisation rates using innovative sediment dating and tracing technologies. The significance of this research lies in its immediate relevance to rural industries and the management of Australian riverine and offshore ecosystems.

Continuum Damage Mechanics in Geotechnical Engineering. Mining and oil exploration are amongst the major industries in Australia and must address geotechnical problems in which growth in damage plays a central role. For example, failure of an offshore platform can occur under cyclic environmental loading, due to accumulated damage to the seabed soils. Design tools are therefore needed that incorporate continuum damage mechanics in modelling the response of geomaterials.

Mining and oil exploration are amongst the major industries in Australia and must address geotechnical problems in which growth in damage plays a central role. For example, failure of an offshore platform can occur under cyclic environmental loading, due to accumulated damage to the seabed soils. Design tools are therefore needed that incorporate continuum damage mechanics in modelling the response of geomaterials. The project will place Australia at the forefront in this field through the development of rigorous yet simple numerical models that achieve this, and thus underpin safe but economic geotechnical engineering solutions in the mineral resource industries.Read moreRead less

Oil and gas exploration is a major industry in Australia. Collapse problems in the soil to which structures such as oil rigs are anchored are a major challenge, involving issues of safety, longevity and maintenance. Research on this topic has been devoted to non-crushable sands, but Australia's offshore seabed is rich in breakable calcareous sediments. We will create a novel theory and visualisation techniques that will allow us to gain a deep understanding of sand crushing and will be a major step towards minimising the occurrence of catastrophic failures in the offshore oil and gas industry.
