A new strategy for design flood estimation in a nonstationary climate. Evidence suggests that global warming will result in an increase in the frequency and/or magnitude of heavy rainfall, leading to flooding with potentially devastating consequences. This study provides a renewed focus on design flood estimation that takes into account a changing climate where assumptions of stationarity are no longer tenable.
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. An approach combining advanced X-ray techniques with particle based methods will be developed to observe, analyse and link different material properties and external conditions governing the erosion process. This ....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. An approach combining advanced X-ray techniques with particle based methods will be developed to observe, analyse and link different material properties and external conditions governing the erosion process. This will lead to better criteria for soil erosion and numerical tools for field scale failure analysis and risk assessments. The expected outcomes of this project include enhanced capability to assess the integrity and stability of earth structures and better design criteria against erosion.Read moreRead less
A kinematically and micromechanically enriched constitutive modelling framework for failure of geomaterials. Failure at large scale such as slopes, embankments, and underground mining is fatal in terms of human lives and property loss. This project aims to develop a new methodology to connect micro-mechanisms that trigger and govern failure with the behaviour at much larger scales. In particular it will allow building constitutive models directly from micro-scale mechanisms, while possessing the ....A kinematically and micromechanically enriched constitutive modelling framework for failure of geomaterials. Failure at large scale such as slopes, embankments, and underground mining is fatal in terms of human lives and property loss. This project aims to develop a new methodology to connect micro-mechanisms that trigger and govern failure with the behaviour at much larger scales. In particular it will allow building constitutive models directly from micro-scale mechanisms, while possessing the capability to span the spatial scales. It will also transform the understanding of material property scaling into a predictive tool for engineering analysis, helping to obtain more cost effective designs with greater confidence in safety.Read moreRead less

Summary
Numerical modeling of hydraulic fracturing for unconventional gas recovery. The project seeks to improve our understanding of the mechanics and physics of hydraulic fracturing in unconventional shale/tight gas reservoirs. By determining key aspects of the mechanics and physics of hydraulic fractures in naturally fractured unconventional reservoirs the project aims to build an accurate continuum hydro-mechanical model for hydraulic fracturing stimulation. The new computational approach and softwa ....Numerical modeling of hydraulic fracturing for unconventional gas recovery. The project seeks to improve our understanding of the mechanics and physics of hydraulic fracturing in unconventional shale/tight gas reservoirs. By determining key aspects of the mechanics and physics of hydraulic fractures in naturally fractured unconventional reservoirs the project aims to build an accurate continuum hydro-mechanical model for hydraulic fracturing stimulation. The new computational approach and software is expected to improve our fundamental understanding of the underlying physics of initiation and propagation of hydraulic fractures and their interactions with pre-existing natural faults. This has the potential to benefit the natural gas industry by providing information for better hydraulic fracture treatments and mitigation of the inherent risks of hydraulic fracturing and other processes.Read moreRead less
Liquefaction of silty soils: Micromechanics, modelling and prediction. The project aims to develop a numerical approach to understand liquefaction in silty soils. Liquefaction of silty soils in submarine landslides, mine tailings dam failures and cargo liquefaction in vessels carrying iron/nickel ores can cause property loss and be fatal. This project will bridge the behaviours across the scales and deliver constitutive models that possess grain scale mechanisms for better prediction of liquefac ....Liquefaction of silty soils: Micromechanics, modelling and prediction. The project aims to develop a numerical approach to understand liquefaction in silty soils. Liquefaction of silty soils in submarine landslides, mine tailings dam failures and cargo liquefaction in vessels carrying iron/nickel ores can cause property loss and be fatal. This project will bridge the behaviours across the scales and deliver constitutive models that possess grain scale mechanisms for better prediction of liquefaction induced failure at the large scales. The expected outcomes are liquefaction criteria for silty soils with different silt contents and numerical tools to predict the onset of liquefaction and flow of liquefied soils.Read moreRead less
