Sustainable usage of dredged clay materials as land reclamation fills. Millions of cubic metres of dredged materials are removed from river and sea beds every year in dredging projects. It is common to dump a significant portion of the dredged spoils into the sea which can result in serious environmental problems such as deterioration of water quality, damage to aquatic habitats, disruption of ecosystems and dispersion of fine clay particles in seawater. The proposed use of dredged clays as land ....Sustainable usage of dredged clay materials as land reclamation fills. Millions of cubic metres of dredged materials are removed from river and sea beds every year in dredging projects. It is common to dump a significant portion of the dredged spoils into the sea which can result in serious environmental problems such as deterioration of water quality, damage to aquatic habitats, disruption of ecosystems and dispersion of fine clay particles in seawater. The proposed use of dredged clays as land reclamation fill will lead to a substantial reduction in or even eliminate the need for dumping dredged clays into offshore dumping locations. The stabilized dredged clays have great potential if their geotechnical characteristics are adequately understood.Read moreRead less
Dynamic Gas Permeability Investigations of Highly Stressed Coals. Coal Bed Methane (CBM) is an emerging energy resource in Australia, which has multi-billion dollar CBM reserves. Gas is clean burning, produces little greenhouse gas and almost no disruption to surface activities (like farming) during extraction. These environmental benefits, with low cost, make gas the fuel of choice for power and heat worldwide. This project seeks to assist development of CBM engineering from deep coal seams.

Gas is clean burning, produces little greenhouse gas and almost no disruption to surface activities (like farming) during extraction. These environmental benefits, with low cost, make gas the fuel of choice for power and heat worldwide. This project seeks to assist development of CBM engineering from deep coal seams. These contain the most gas, but are technically more difficult to develop than shallower reservoirs. In particular, it examines how natural and induced stress fields can be used to improve productivity, by understanding the relationships between different coal types, their environment and gas production rate.Read moreRead less
The Influence of particle shape fragmentation and compaction on 3D hopper flow. According to world-leading material scientist Patrick Richard, "Granular materials are ubiquitous in nature and are the second-most manipulated material in industry (the first one is water)". Our research will produce massive three dimensional computer simulations predicting and analysing the influence of particle size and shape on the morphology of industrial and natural granular flows. The results will have directl ....The Influence of particle shape fragmentation and compaction on 3D hopper flow. According to world-leading material scientist Patrick Richard, "Granular materials are ubiquitous in nature and are the second-most manipulated material in industry (the first one is water)". Our research will produce massive three dimensional computer simulations predicting and analysing the influence of particle size and shape on the morphology of industrial and natural granular flows. The results will have directly and immediately relevant applications in a range of Australian industries, including mass mining and minerals processing and will further make a major contribution to understanding and modelling a variety of geo-hazards.
