On-line monitoring of cyanobacteria to predict coagulant doses and powdered activated carbon application in water treatment. Cyanobacteria, more commonly known as blue-green algae, can impact water quality by releasing toxins that can be harmful to human health and imparting unpleasant taste and odours to the water. This project will support the water industry in managing these risks by providing a rapid, on-line tool to assist in their removal during water treatment.
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
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

Modelling rolling dynamic compaction. This project aims to measure the influence and efficacy of rolling dynamic compaction (RDC)—a new ground improvement technology used worldwide—in soil types using RDC modules of different shapes and weights in an experimental testing facility. It will examine authentic 1:13 scale RDC models using sophisticated testing and instrumentation embedded in the soil, and use this data to develop a model based on artificial intelligence techniques that reliably predicts ground improvement using RDC in different ground conditions. This research is expected to transform the Australian and global ground improvement sector, and save hundreds of millions of dollars in land development costs and infrastructure.Read moreRead less

The project aims to improve the effectiveness of geosynthetic liner systems to contain emerging contaminants such as per-and poly-fluoroalkyl substances (PFASs) for better protection of Australian groundwater resources. The project expects to experimentally validate theory to improve predictive models for performance of geosynthetic liner systems. Expected outcomes include new and updated design guidelines for effective environmental protection against PFASs and establishment of new approaches for predicting functional containment lifetimes of liner systems. These outcomes are expected to benefit the waste and remediation industries by influencing next-generation design regulations to ensure long-term environmental protection from PFAS.Read moreRead less
Combining transient micro-reflections and multi-sensor arrays for condition assessment of buried pipes. This project will develop an accurate and reliable approach for assessing the condition of pipelines. This new approach will reduce costs and save considerable amounts of water each year, as it will assist utilities in preventing major failures such as pipe bursts, and performing strategically targeted maintenance, replacement and rehabilitation.
Optimization of internal pressure for designing industrial buildings. The project seeks to understand the internal pressure in a building during windstorms, to improve safety and performance. The internal pressure in a building is dependent on its volume and flexibility and the sizes of openings in the building envelope, and is a critical loading parameter in building design. Windstorm damage investigations have shown that incorrect internal pressures are frequently used in building design, lead ....Optimization of internal pressure for designing industrial buildings. The project seeks to understand the internal pressure in a building during windstorms, to improve safety and performance. The internal pressure in a building is dependent on its volume and flexibility and the sizes of openings in the building envelope, and is a critical loading parameter in building design. Windstorm damage investigations have shown that incorrect internal pressures are frequently used in building design, leading to damage. This project aims to study the internal pressures generated in buildings with a range of volumes and openings in the envelope. A combination of model-scale and full-scale tests and theoretical analysis are planned to determine critical parameters for highly turbulent air-flow though openings. Results will inform the revision of design data in codes and of guidelines for consistent, optimal design of buildings.Read moreRead less
