The project will aim to collate data and map base-level distribution patterns of molecular and microbial markers of human sewage and natural/agricultural contamination with reference to diurnal and seasonal fluctuations. These data will then be used to develop decision support systems that predict contaminant dispersion and identify high-risk contamination sources. The diurnal collection of data is expected to show significant variations in the measured parameters associated with time of day, light intensity and temperature. Mapping of the sewage and nutrient loads throughout the year will provide base line data for identifying potential hotspots for targeting system upgrades or improved management programs.Read moreRead less
Accelerating Consolidation and Closure of Mine Tailings Storage Facilities. All mining operations involve the production of waste. Many regard such waste (tailings) and their environmentally acceptable storage as constituting the largest waste problem on Earth because of the enormous damage and loss-of-life that have resulted from failures of tailings storage facilities. This project focuses on a dewatering technology, electro-osmosis (EO), which has yet to be fully operationalised, for improvin ....Accelerating Consolidation and Closure of Mine Tailings Storage Facilities. All mining operations involve the production of waste. Many regard such waste (tailings) and their environmentally acceptable storage as constituting the largest waste problem on Earth because of the enormous damage and loss-of-life that have resulted from failures of tailings storage facilities. This project focuses on a dewatering technology, electro-osmosis (EO), which has yet to be fully operationalised, for improving the strength, stability and settlement characteristics of the tailings. Sophisticated testing will be undertaken at three scales (lab, meso and, most importantly, field), as well as the development of generic numerical models, to create practical guidelines to facilitate the implementation of EO in mines around the world.Read moreRead less

Preventing mining disasters: reducing the risk of tailings dam failure. This project aims to improve safety of tailings storage facilities (TSFs). Mineral processing produces waste called tailings, being mixtures of water and soil-sized particles. Tailings are stored on sites contained by embankments made from soil or a coarse component of tailings. Sections of the TSFs are partially saturated, have high concentrations of fine particles and physically change with age. Their resistance to earthqu ....Preventing mining disasters: reducing the risk of tailings dam failure. This project aims to improve safety of tailings storage facilities (TSFs). Mineral processing produces waste called tailings, being mixtures of water and soil-sized particles. Tailings are stored on sites contained by embankments made from soil or a coarse component of tailings. Sections of the TSFs are partially saturated, have high concentrations of fine particles and physically change with age. Their resistance to earthquake loading and liquefaction, and strength post-earthquake, arising from these properties are poorly understood and can not be quantified reliably so will be addressed here. Anticipated outcomes will be updated industry guidelines for the design and management of TSFs. Mines will benefit and failures will be prevented.Read moreRead less

Transport infrastructure is one of the seven types of nationally significant critical infrastructure identified federally to ensure the continuity of essential services in the face of extreme events including terrorist attacks and natural disasters. This project aims to provide tools for determining the most cost efficient schedule of preventative strengthening works for road networks for reducing the disruption and recovery costs after extreme events. The project aims to develop a novel platform for increasing the resilience of road networks by blending transport resilience modelling and structural health vulnerability analysis of road infrastructure into one integrated spatially enabled road transport planning system.Read moreRead less

Project aims to further develop an engineering model for cost-effective innovative flood safety design/review for private dams in Southeastern Australia and integrate this with community impact assessment. Together, this is a "community partnerships" solution to a significant water policy vacuum on private dam safety and flood policy. Expected outcomes: improved risk transparency for dam owners and State Government, minimising costs of failures, ie. loss of life, damage to public and private infrastructure and environment; giving owners an affordable and effective design/review procedure to better manage their dams, providing data on community responses and water law reform proposals consonant with international best-practice.Read moreRead less
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

This project should provide significant benefits by improving soil management for mining remediation, increasing carbon dioxide storage efficiency, and preventing the deterioration of tailings dams.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
