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.
Development and Modellling of Advanced Coagulation and Oxidation Processes. The success of this program will help place Australia at the forefront of water quality control and management research. It will address concerns with managing and treating waters of changing characteristics due to climate change. In addition to the socio benefits, project success will also impart economic benefits to the nation through (i) fabricating new hybrid coagulants, that are versatile with enhanced performance ....Development and Modellling of Advanced Coagulation and Oxidation Processes. The success of this program will help place Australia at the forefront of water quality control and management research. It will address concerns with managing and treating waters of changing characteristics due to climate change. In addition to the socio benefits, project success will also impart economic benefits to the nation through (i) fabricating new hybrid coagulants, that are versatile with enhanced performance for removing NOM, and possess antimicrobial properties (ii) developing a new energy efficient photocatalysis technology.The proposed research will expand the knowledge base in this area and increase Australia’s international profile as a global leader in developing cutting-edge cost effective water resource technologies.Read moreRead less
Optimising permeable pavements with underlying reservoirs to enhance urban tree performance. This project will determine the optimal configuration of permeable pavements with underlying storage reservoirs and water delivery system to resolve the water security challenges that trees face in urban environments. This project will promote the healthy growth of urban trees and will lead to more liveable and healthier cities.
Bad tastes, odours and toxins in our drinking water reservoirs: are benthic cyanobacteria the culprits? Cyanobacteria (blue-green algae) produce toxins and bad tastes that contaminate drinking water sources, cause public concern about water quality. This project will address a critical knowledge gap by investigating species that grow on the sediments of reservoirs, thus providing more comprehensive management solutions to the water industry.
Phytocapping for sustainable waste containment systems and reduction of greenhouse gas emissions and odour from waste disposal sites. Landfills remain the main method of waste disposal in Australia and are a major source of groundwater contamination and greenhouse and odour emissions. This national research program will establish, under a wide range of Australian conditions, whether landfill phytocaps can meet regulatory performance criteria for water infiltration into and gas emissions from clo ....Phytocapping for sustainable waste containment systems and reduction of greenhouse gas emissions and odour from waste disposal sites. Landfills remain the main method of waste disposal in Australia and are a major source of groundwater contamination and greenhouse and odour emissions. This national research program will establish, under a wide range of Australian conditions, whether landfill phytocaps can meet regulatory performance criteria for water infiltration into and gas emissions from closed landfills more effectively, efficiently and sustainably than conventional capping systems. The project will produce (a) a scientific basis for site owners and regulators to agree on the performance and cost of conventional and phyto cover technologies, (b) a manual for the design and permitting of alternative covers and (c)improved scientific prediction of cover performance.Read moreRead less
Understanding the fluid mechanics of unsteady friction. Unsteady fluids flows are common in the fields of technology, engineering and physiology. This project brings together a multi-disciplinary team to consider the issue of unsteady friction. The research will focus on understanding the behaviour of water in pipes when subject to very fast transient events (such as those which cause the common problem of water hammer in the home). The project will produce new results that will be used by water ....Understanding the fluid mechanics of unsteady friction. Unsteady fluids flows are common in the fields of technology, engineering and physiology. This project brings together a multi-disciplinary team to consider the issue of unsteady friction. The research will focus on understanding the behaviour of water in pipes when subject to very fast transient events (such as those which cause the common problem of water hammer in the home). The project will produce new results that will be used by water engineers to design improved techniques for the rapid non-invasive identification of leaks in underground pipelines. As such our research has the potential to contribute huge savings to Australia's increasingly valuable water resources. Read moreRead less
Dynamic Release Mechanisms for Phosphorus in Shallow Ponds and Lakes. Phosphorus release from submerged sediments is controlled by the physical and chemical environment. The mechanisms are well understood where thermal stratification is persistent but the behaviour during transient episodes has not been properly addressed. The aim is to study a dynamic chemical and hydraulic environment and develop a model of phosphorus release under these conditions. Algal blooms, which rely on high nutrient co ....Dynamic Release Mechanisms for Phosphorus in Shallow Ponds and Lakes. Phosphorus release from submerged sediments is controlled by the physical and chemical environment. The mechanisms are well understood where thermal stratification is persistent but the behaviour during transient episodes has not been properly addressed. The aim is to study a dynamic chemical and hydraulic environment and develop a model of phosphorus release under these conditions. Algal blooms, which rely on high nutrient concentrations, pose a significant threat to waterways yet a process-based description of phosphorus release is not yet possible. The outcome will be a verified model of phosphorus release mechanisms suitable for a range of water bodies.Read moreRead less
A new strategy for design flood estimation in a nonstationary climate. Evidence suggests that global warming will result in an increase in the frequency and/or magnitude of heavy rainfall, leading to flooding with potentially devastating consequences. This study provides a renewed focus on design flood estimation that takes into account a changing climate where assumptions of stationarity are no longer tenable.
Continuous non-invasive assessment of the physical condition of water distribution systems. Water distribution systems represent the single most important part of a society's infrastructure yet there are no comprehensive methods for detecting or assessing their physical condition. A suite of techniques (including those adapted from radar and sonar) for pro-active condition assessment will be developed in this research. The objective is to add significant intelligent and sophisticated numerical m ....Continuous non-invasive assessment of the physical condition of water distribution systems. Water distribution systems represent the single most important part of a society's infrastructure yet there are no comprehensive methods for detecting or assessing their physical condition. A suite of techniques (including those adapted from radar and sonar) for pro-active condition assessment will be developed in this research. The objective is to add significant intelligent and sophisticated numerical modelling capability to enable the non-invasive analysis of the transient pressure data, and to enable real-world application. This research will enable the continuous assessment of the physical condition of the entire water distribution system from an operations room resulting in significant savings.Read moreRead less

The project outcomes will have significant implications for government water policies and private and public sector water-infrastructure investment. It will be the first detailed study of large-scale municipal desalting costs under Australian conditions.Read moreRead less
