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
Understanding the role of vegetation in nitrogen removal by biofiltration. Many of Australia's bays and waterways are threatened by eutrophication due to excess nitrogen loads, particularly from urban stormwater. Biofiltration systems are a widely used (Melbourne Water alone has a programme of constructing 10000 systems in partnership with municipalities over the next 5 years) and potentially effective treatment, but their nitrogen removal is highly dependent on the type of vegetation used. Th ....Understanding the role of vegetation in nitrogen removal by biofiltration.

Biofiltration systems are a widely used (Melbourne Water alone has a programme of constructing 10000 systems in partnership with municipalities over the next 5 years) and potentially effective treatment, but their nitrogen removal is highly dependent on the type of vegetation used. This project will improve the understanding of the role of vegetation in nitrogen retention by stormwater biofilters, and will thus provide important guidance on plant selection and design for biofiltration.Read moreRead less

Thin-walled Structures Subjected to Impact and Blast Loading. Terrorist attacks have cost Australians much human grief and billions of dollars. Containing the consequences of a blast or impact is crucial to survival and restricting damage to critical civilian/defence infrastructure. Thin-walled structures are used extensively in such infrastructure. There is a lack of knowledge about their behaviour when subjected to impulse and blast loads.

Terrorist attacks have cost Australians much human grief and billions of dollars. Containing the consequences of a blast or impact is crucial to survival and restricting damage to critical civilian/defence infrastructure. Thin-walled structures are used extensively in such infrastructure. There is a lack of knowledge about their behaviour when subjected to impulse and blast loads. The investigators will establish the most economical means of designing passive blast protection into thin-walled structures and hence, Australia's critical infrastructure. This knowledge will be transferred into design standards and Australia's limited defence resources.Read moreRead less
Thermo-hydro-mechanics of geosynthetic liners: from processes to prediction. 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.

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

Investigation of Geopolymer based Concretes for the Construction of High Fire Risk Infrastructures. Geopolymer concretes are emerging new materials promising superior fire resistance and durability and potentially cheaper than the widely used high strength concretes, which also consume high levels of Portland cements. Production of 1 ton of Portland cement releases 1 ton of green house gases. Further, the 6.5 million tons/year of cement currently produced in Australia is insufficient to meet the ....Investigation of Geopolymer based Concretes for the Construction of High Fire Risk Infrastructures. Geopolymer concretes are emerging new materials promising superior fire resistance and durability and potentially cheaper than the widely used high strength concretes, which also consume high levels of Portland cements. Production of 1 ton of Portland cement releases 1 ton of green house gases. Further, the 6.5 million tons/year of cement currently produced in Australia is insufficient to meet the industry demand. This project investigates the use of fly ash to make geopolymer concrete, without using any Portland cement, to find usage for part of the 11 million tons/year of fly ash produced as a waste from coal power stations in Australia.Read moreRead less
Development of an Alkali Activated Slag based Construction Material for High Fire Risk Infrastructures. This project will develop an alkali-activated slag (AAS) based construction material for tunnel construction. In tunnels, conventional concretes are likely to 'spall' in a hydrocarbon fire accident, possibly resulting in a tunnel collapse. The project is set to develop a spalling-resistant AAS as an alternative to conventional Portland cement, which is responsible for 6.5 million tons of gre ....Development of an Alkali Activated Slag based Construction Material for High Fire Risk Infrastructures. This project will develop an alkali-activated slag (AAS) based construction material for tunnel construction. In tunnels, conventional concretes are likely to 'spall' in a hydrocarbon fire accident, possibly resulting in a tunnel collapse. The project is set to develop a spalling-resistant AAS as an alternative to conventional Portland cement, which is responsible for 6.5 million tons of greenhouse gas emissions in Australia per year, whereas AAS is based on slag, an industrial waste product. The project also seeks to provide better understanding of the spalling phenomenon so that the engineers can design fireproofing for conventional concrete tunnels with confidence.Read moreRead less

This project aims to explore health risks from water- and sediment-borne bacteria to recreational users of urban rivers, using a suite of novel molecular microbiological and in-vitro assays and microbial risk assessment modelling. This project also aims to develop source tracking methods to mitigate and manage these risks. The number of bacterial-related water-borne outbreaks associated with recreational activities is rising, but waterway managers are under pressure to re-open these rivers for recreation. The project is expected to benefit urban communities by ensuring waterway managers make informed decisions about river recreation.Read moreRead less
