Enhanced Prediction of Landfill Gas Emissions Through Geosynthetic Systems. Landfill gas represents an opportunity for electricity generation and carbon abatement: it need not be managed solely for environmental, health or safety risk reasons. However, our ability to predict gas collection and fugitive emissions from landfills capped with geosynthetics liners, in consideration of the myriad of factors that control these processes, is imperfect. Building on recent advances in unsaturated soil mec ....Enhanced Prediction of Landfill Gas Emissions Through Geosynthetic Systems. Landfill gas represents an opportunity for electricity generation and carbon abatement: it need not be managed solely for environmental, health or safety risk reasons. However, our ability to predict gas collection and fugitive emissions from landfills capped with geosynthetics liners, in consideration of the myriad of factors that control these processes, is imperfect. Building on recent advances in unsaturated soil mechanics, this project aims to conduct cutting-edge experimental and theoretical research to develop an experimentally-validated theory of gas migration through geosynthetics systems that is expected to lead to major improvement in performance and provide integrated design tools which are much needed but not currently availableRead moreRead less
Improved predictions of greenhouse gas transfers in landfill composite liner covers containing geomembrane defects. The Australian Greenhouse Office indicated that methane accounted for 85 per cent of the waste sector's annual greenhouse emissions in 2008, and stressed the need to undertake a range of activities to reduce these emissions. Models and theories derived from this project will address specifically the above issue leading to enhanced economic benefits.

Linking microstructural evolutions across the scales of granular failure. This project expects to transform the understanding of granular materials and their behaviour by establishing explicit links between the macroscopic responses of the materials and their evolving microstructural properties. This should lead to revolutionary constitutive models for granular materials that possess true mechanisms of evolving grain-scale structures. The proliferation of these new models should allow developmen ....Linking microstructural evolutions across the scales of granular failure. This project expects to transform the understanding of granular materials and their behaviour by establishing explicit links between the macroscopic responses of the materials and their evolving microstructural properties. This should lead to revolutionary constitutive models for granular materials that possess true mechanisms of evolving grain-scale structures. The proliferation of these new models should allow development of reliable predictive computational tools for the modelling and assessment of field-scale failure involving granular materials, enhancing the capability to assess the integrity and stability of earth structures, and benefitting the Australian economy, environment and public safety.Read moreRead less
Internal soil erosion: from grain-scale insights to large-scale predictions. This project aims to further the understanding of internal soil erosion across different spatial and temporal scales. Internal soil erosion is the most frequent cause of failures of water retaining structures.

Experimental and theoretical analysis of gas leakage rate through composite landfill covers due to geomembrane defects. The Australian Greenhouse Office indicated that waste emissions contributed 3.1% of net national emissions in 2001 with methane emissions from landfills accounting for 92% of total methane emissions from the waste sector, despite an increase in methane recovered from solid waste.

The Australian Greenhouse Office indicated that waste emissions contributed 3.1% of net national emissions in 2001 with methane emissions from landfills accounting for 92% of total methane emissions from the waste sector, despite an increase in methane recovered from solid waste. It pointed out that the recent changes in waste management practices did not have an impact on reported methane emission levels and there is need to undertake a range of activities to reduce emissions from waste management activities. This project will address specifically the above issue by providing a new method of analysis to predict gas leakage rate and allow engineers to propose solutions to mitigate gas escapes.
