Summary
Imaging, analysing and forecasting Australian hazards with satellites. This project aims to improve Australia’s ability to anticipate geophysical hazards. It will generate a new national capability in the use of satellite radar imagery to monitor and manage geohazards, benefiting all communities. By producing high-resolution maps of ground displacements, the project will assess the controls upon where and why these events occur, and whether they exhibit precursory behaviour.

It will generate a new national capability in the use of satellite radar imagery to monitor and manage geohazards, benefiting all communities. By producing high-resolution maps of ground displacements, the project will assess the controls upon where and why these events occur, and whether they exhibit precursory behaviour. This is the first step towards accurate hazard forecasting and in building Australia's capability for near-real-time geophysical hazard monitoring on a national scale. The outputs will impact upon future recommendations for national earthquake and landslide monitoring and deliver new tools to underpin regulation of resource extraction and inform construction codes.Read moreRead less

The Australian tectonic stress state: Far-field forces and local impacts. This project aims to investigate the present-day tectonic stress field of Australia using detailed analysis of stress magnitude data and state-of-the-art 3D geomechanical-numerical modelling across spatial scales.

This project aims to investigate the present-day tectonic stress field of Australia using detailed analysis of stress magnitude data and state-of-the-art 3D geomechanical-numerical modelling across spatial scales. Tectonic stresses control the Earth’s deformation and are a primary cause of collapse of subsurface structures. This project expects to improve our knowledge of the causes of the tectonic stress field of Australia and its consequences for earthquake risk assessment, safe and sustainable usage of underground environments for groundwater exploration and production, CO2 sequestration, waste disposal, mine stability, exploration and production of hydrocarbon and geothermal resources.Read moreRead less
A unified approach for estimating coastal flood risk. The project aims to develop a unified approach to quantifying flood risk. Because flooding is caused by multiple mechanisms such as extreme rainfall, storm surge and astronomical tide, accurately estimating flood levels in the Australian coastal zone is challenging. By quantifying flood risk in terms of these mechanisms, the project is expected to provide reliable flood risk estimates for both historical settings and future climate scenarios. ....A unified approach for estimating coastal flood risk.

By quantifying flood risk in terms of these mechanisms, the project is expected to provide reliable flood risk estimates for both historical settings and future climate scenarios. The improved estimation should enable Australian water agencies and policy-makers to effectively design defence infrastructure (e.g. drainage systems) and urban planning policies to adapt to future flood risk.Read moreRead less

Dynamic Fracturing and Energy Release Mechanisms in Heterogeneous Materials. The prediction of fracturing behaviour in geomaterials (i.e. rock, soil and concrete) under dynamic/impact loads is essential in dealing with a wide range of engineering problems including excavation and mining, blasting and fragmentation, earthquake engineering, impact cratering, and protective structure design However, current knowledge and modelling capabilities of these applications remains empirically based.

This project aims to investigate fundamental issues governing the dynamic fracturing of geomaterials and apply this knowledge to advance the understanding and modelling capacity of dynamic fractures in geomaterials.Read moreRead less

The project aims to use the microwave link data between mobile phone towers to complement the sparse rain gauge network in urban areas, to allow more accurate near-real-time monitoring of rainfall. Accurate near-real-time precipitation data at high resolution are critical to flash flood forecasting in and around Australia's capital cities. Current estimates suffer from the limited availability of rain gauge data in urban areas. However, mobile phone towers abound and the microwave links between them can provide information on rainfall intensity, meaning that these data could be used to supplement the rain gauge data. This project plans to develop the technology to generate precipitation maps using mobile phone network link, rain gauge and weather radar data.Read moreRead less

Summary
Coupled thermo-hydro-mechanical behaviour of unsaturated soils and its modelling. This project will study the fundamental behaviour of natural soils under varying environmental conditions such as suction, moisture, temperature and loading conditions. The outcomes of the work will improve infrastructure design methods and reduce damage costs associated with natural soils.
Contemporary stress and tectonics of Australia. This project will conduct a detailed examination of the state and controls on present-day tectonic stress in Australia. Tectonic stresses are a primary control on deformation in the Earth and this project has direct applications for earthquake hazard assessment, mine stability, production of petroleum and geothermal energy, and carbon dioxide sequestration.
