Summary
Safe distractions? Taking the danger out of competing activities. Distracted driving is an increasing safety concern in Australia and worldwide. Smartphones play key roles in today’s professional and social contexts and current road safety policies based on stopping their use while driving have shown little success. Distraction is predicted to be an even greater issue in new semi-automated vehicles. This project proposes an innovative approach that will enable safe engagement in competing tasks ....Safe distractions? Taking the danger out of competing activities. Distracted driving is an increasing safety concern in Australia and worldwide. Smartphones play key roles in today’s professional and social contexts and current road safety policies based on stopping their use while driving have shown little success. Distraction is predicted to be an even greater issue in new semi-automated vehicles. This project proposes an innovative approach that will enable safe engagement in competing tasks while driving non-automated and semi-automated vehicles. The outcomes will underpin the development of new technologies to reduce the potential adverse effects of these distractions and thus reduce deaths and serious injuries, representing significant cost savings to the health system and the community.Read moreRead less

Summary
Multiscale modelling of fluid–particle transport in porous media. The aim is to use a multiscale approach to rigorously model fluid–particle transport in porous media – a fundamental process in many engineering problems. With advanced parallel-computing tools, a microscale model is developed to incorporate interacting grains, water, and particles.

The aim is to use a multiscale approach to rigorously model fluid–particle transport in porous media – a fundamental process in many engineering problems. With advanced parallel-computing tools, a microscale model is developed to incorporate interacting grains, water, and particles. The model and innovative upscaling methods will transform our understanding of mechanisms, and allow development of predictive models for particle transport in both steady and unsteady porous flows. The fundamental knowledge and new-generation numerical models will support technological advances to directly benefit rail and road construction and their maintenance, fuel and renewable-energy extraction, coastal soil and water protection, and bushfire control.Read moreRead less

This project is aimed at advancing theoretical, computational and experimental bases for the fracturing of geomaterials, and providing scientists and engineers with much needed predictive tools for quantitative assessment of the responses. By incorporating previously neglected aspects such as energy minimisation, advanced constitutive modelling, and non-planar interacting fracture growth, confidence in the design and planning of engineering processes in fractured porous media will be increased to the point that costly over/under designs are avoided. Through the use of the tools developed, it will be possible to detect weaknesses in the design, assess the impact and implement effective measures to improve performance.Read moreRead less
Experimental investigation and constitutive modelling of reactive soils. This project aims to develop the fundamental knowledge, a mechanical framework and practical engineering design tools needed to minimise the effects of reactive soils on infrastructure. Reactive soils undergo significant swelling and weakening upon wetting or intrusion by salt-rich groundwater and shrinkage upon drying. This can result in damage to buildings and infrastructure beyond a state of repair. This project will dev ....Experimental investigation and constitutive modelling of reactive soils. This project aims to develop the fundamental knowledge, a mechanical framework and practical engineering design tools needed to minimise the effects of reactive soils on infrastructure. Reactive soils undergo significant swelling and weakening upon wetting or intrusion by salt-rich groundwater and shrinkage upon drying. This can result in damage to buildings and infrastructure beyond a state of repair. This project will develop tools, models and theories to detect weaknesses in the design of infrastructure and its foundations built on problematic reactive soils, assess the impact and implement effective remedial measures to improve performance. The project is expected to increase efficiency through improved design and reduced damage, and save infrastructure owners, government and private, tens of millions of dollars each year.Read moreRead less

New techniques will be developed for reliable and timely detection using the existing sensor network in the Adelaide CBD. Specialised monitoring stations will be developed with adaptive noise-cancellation algorithms to detect small leak signals in noisy city environments. Expected outcomes include an effective pipe burst early warning system and the implementation of an active burst prevention and targeted pipe replacement strategy. This should significantly reduce the burst rates and associated interruptions in Adelaide and save millions of dollars every year in pipe relay programs.Read moreRead less

The project will address previously neglected aspects of soil behaviour, such as gradual changes in physical properties with time and strain-rate dependency. The project is expected to enable better predictions of infrastructure performance, improve confidence in design, and avoid unwarranted over-design and the considerable cost this imposes. The project will provide a fully validated predictive computational modelling tool for quantitative assessment of long-term performance and stability of infrastructure such as dams, embankments, tunnels, slopes, buildings and foundations.Read moreRead less

Summary
Resilient design flood estimation for Australia. The total costs of natural disasters in Australia are forecast to more than double in the next 20 years - with floods one of the costliest natural disasters faced. The damage and cost of floods can be managed, but rapid developments in the understanding of rainfall and flood projections has resulted in national flood guidelines that are not consistent with current science. This project proposes a novel but practical technique for design flood esti ....Resilient design flood estimation for Australia. The total costs of natural disasters in Australia are forecast to more than double in the next 20 years - with floods one of the costliest natural disasters faced. The damage and cost of floods can be managed, but rapid developments in the understanding of rainfall and flood projections has resulted in national flood guidelines that are not consistent with current science. This project proposes a novel but practical technique for design flood estimation that will accommodate the key changes to flood behaviour that are expected in the future. This will include consideration of changes in extreme rainfall intensities, catchment wetness, and patterns of storm behaviour.Read moreRead less
Erosion processes in soils across scales. This project aims to develop a monitoring tool for predicting the evolution of internal erosion in dams based on innovative electromagnetic observation methods. Internal erosion is an insidious process occurring in the obscurity of the soil’s pore system until its consequences become visible and threaten the stability of the dams. These water retaining structures are vital for the future water and energy supply for our society and their failure can be ca ....Erosion processes in soils across scales. This project aims to develop a monitoring tool for predicting the evolution of internal erosion in dams based on innovative electromagnetic observation methods. Internal erosion is an insidious process occurring in the obscurity of the soil’s pore system until its consequences become visible and threaten the stability of the dams. These water retaining structures are vital for the future water and energy supply for our society and their failure can be catastrophic. By establishing an improved understanding of internal erosion as a sequence of processes on various scales, from the onset of erosion until the failure of the structure, this project will place Australia at the forefront of dam safety assessment.Read moreRead less

Water assets are critical infrastructure, and they consist of a network of buried pipes that are old and deteriorating, with an annual maintenance overhead exceeding $1billion per year in Australia. This project is expected to deliver next-generation smart water technology that enables continuous assessment of the actual performance of water pipe networks, guide “just in time” pipe replacement and optimise operations. This technology will assist asset managers to make informed decisions, strategically prioritise investment and extend asset life.Read moreRead less
