Fragmentation of rocks upon impact. The project aims to create a new understanding of how rocks fragment upon impact to allow more realistic predictions of rockfall hazards. Rockfall results in loss of human life, damage to infrastructure and economic loss; each year in Australia, millions of dollars are spent on rockfall protection. To mitigate rockfall risk, it is important to understand and predict how blocks break as they fall down a slope. Unfortunately, there is limited data and knowledge ....Fragmentation of rocks upon impact. The project aims to create a new understanding of how rocks fragment upon impact to allow more realistic predictions of rockfall hazards. Rockfall results in loss of human life, damage to infrastructure and economic loss; each year in Australia, millions of dollars are spent on rockfall protection. To mitigate rockfall risk, it is important to understand and predict how blocks break as they fall down a slope. Unfortunately, there is limited data and knowledge on this phenomenon. This project aims to produce a comprehensive, high-quality database of fragmentation events and develop an innovative fragmentation model that can be included in existing rockfall codes. This project is expected to lead to optimised and cost-effective rockfall barrier protection measures.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
Forecasting drought impacts months ahead using satellite data. Skillful seasonal water and crop forecasts could do much to help cope with drought and water-related food crises. Recent advances in hydrological modelling and satellite remote sensing of surface soil moisture, landscape water storage and vegetation biomass have created a great opportunity to produce such forecasts over large areas.

Skillful seasonal water and crop forecasts could do much to help cope with drought and water-related food crises. Recent advances in hydrological modelling and satellite remote sensing of surface soil moisture, landscape water storage and vegetation biomass have created a great opportunity to produce such forecasts over large areas. This project will exploit that opportunity by assimilating the satellite observations into a global water and vegetation forecasting model. The resulting improvement in seasonal forecasts of stream flow, soil moisture and crop production will be quantified and compared to the limited forecasts that are currently available.Read moreRead less

Extreme events will significantly impact the severity of Australian rock cliff hazards in the coming years affecting infrastructure and public safety along major corridors and popular paths. Accurate prediction of their effect is crucial to analyse the associated rockfall risks and design mitigation measures. The project aims to provide a novel approach for the quantification of the rockfall risk by combining proximity remote sensing solutions, probabilistic models and quantitative risk analysis. The primary benefits lie in the ability to optimize protection reliability and costs and to deliver a rigorous method to support practitioners, government and emergency agencies to manage the risk, improve safety and properly allocate resources.Read moreRead less

This project aims to tackle the scientific challenges of using screw piles as foundations for deep water offshore wind turbines. Current foundations for offshore infrastructure developments have reached their limits, and conventional screw piles are designed for land use. This project will use innovative geotechnical methods to develop verified designs, guidelines and numerical tools for predicting the forces required to install screw piles into the seabed and their capacity to resist extreme wind and wave forces relevant to these structures. As foundations cost up to 35% of construction, screw piles will provide significant economic and environmental benefits in reducing costs and unlocking substantial renewable energy from our oceans.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
