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
Fundamental theoretical investigation of the chemomechanical properties of clays. Australia faces significant environmental challenges, one of the most important being soil degradation. The aim of this project is to develop new and state-of-the art mathematical models describing the behaviour of clays in soils. This proposal addresses five fundamental problems in clay soil behaviour that have so far remained unanswered. The primary outcomes of this project will be new theoretical insights into t ....Fundamental theoretical investigation of the chemomechanical properties of clays. Australia faces significant environmental challenges, one of the most important being soil degradation. The aim of this project is to develop new and state-of-the art mathematical models describing the behaviour of clays in soils. This proposal addresses five fundamental problems in clay soil behaviour that have so far remained unanswered. The primary outcomes of this project will be new theoretical insights into the chemomechanical properties of clay soils, so providing the understanding required to intelligently engineer and manage our natural and built environments.Read moreRead less
Study of Coupled Water-Gas-Sediment (three-phase) Flows through Jointed and Stratified Rock. Coupled Water-Gas-Sediment Flows through Rock Joints project outcomes are expected to surpass the current knowledge on ground/slope stability and water inundation, enhance engineering solutions of the associated problems and provide vital improvements to public safety. The research team will publish the research outcomes through peer-reviewed journals and conferences, nationally and internationally, rais ....Study of Coupled Water-Gas-Sediment (three-phase) Flows through Jointed and Stratified Rock. Coupled Water-Gas-Sediment Flows through Rock Joints project outcomes are expected to surpass the current knowledge on ground/slope stability and water inundation, enhance engineering solutions of the associated problems and provide vital improvements to public safety. The research team will publish the research outcomes through peer-reviewed journals and conferences, nationally and internationally, raising Australia’s scientific profile within the civil engineering and mining community. The Australasian Institute of Mining and Metallurgy and Institution of Engineers seminars will be organised to promote discussion with the practitioners while the Australian geotechnical community will gain expertise through the PhD program.

Theoretically derived calibration of the neutron moisture meter. The moisture content of soils is of key importance in a wide range of situations including agriculture, engineering and land and water management. The measurement of soil moisture contents in the field is problematic, and even commonly used methods like the neutron probe give results of limited accuracy. This research will enable calibration curves for the neutron probe to be determined theoretically, thereby improving the accuracy ....Theoretically derived calibration of the neutron moisture meter.

The measurement of soil moisture contents in the field is problematic, and even commonly used methods like the neutron probe give results of limited accuracy. This research will enable calibration curves for the neutron probe to be determined theoretically, thereby improving the accuracy of moisture content measurements and enhancing its usefulness to industry and research.Read moreRead less
