Mega spatial-scale, multi time-scale, ensemble assessment of climate change driven coastal change in South Eastern Australia. Climate change driven variations in mean sea level, storm surges, and waves will change the world's coastline. This project will, for the first time, develop innovative modelling methods to quantify the integrated impact of these climate drivers on coastal erosion along Australia's most developed and populated coastline: Sydney to Brisbane.

Hydrologic effects of human and climatic stresses in water-limited areas: role of coevolving runoff, vegetation and landforms for adaptive management. Semiarid rangelands cover over 70 per cent of the Australian continent. These areas already face serious degradation problems. Observed trends in rainfall variability indicate that high rainfall pulses and dry periods will intensify, with serious implications for hydrology and erosion. The impact of these trends in addition to increasing human pre ....Hydrologic effects of human and climatic stresses in water-limited areas: role of coevolving runoff, vegetation and landforms for adaptive management. Semiarid rangelands cover over 70 per cent of the Australian continent. These areas already face serious degradation problems. Observed trends in rainfall variability indicate that high rainfall pulses and dry periods will intensify, with serious implications for hydrology and erosion. The impact of these trends in addition to increasing human pressures could have devastating socioeconomic consequences for these areas. This project, by examining in detail the hydrologic and soil transport processes in semiarid rangelands, will lead to: better understanding of the dryland response to anthropogenic and climatic stresses; and, improvement of strategies and methods for the management and restoration of these areas.Read moreRead less
Nitrogen Removal in Wastewater Treatment Using the Nitrite Pathway. Nitrogen removal from our wastewater is becoming very important in most parts of Australia to protect our unique aquatic environment. This removal is achieved biologically through two steps: Nitrification converts ammonium via nitrite to nitrate; and denitrification converts nitrate via nitrite again to harmless nitrogen gas. This project aims to develop a method that allows this process to go just via nitrite, instead of nitrat ....Nitrogen Removal in Wastewater Treatment Using the Nitrite Pathway. Nitrogen removal from our wastewater is becoming very important in most parts of Australia to protect our unique aquatic environment. This removal is achieved biologically through two steps: Nitrification converts ammonium via nitrite to nitrate; and denitrification converts nitrate via nitrite again to harmless nitrogen gas. This project aims to develop a method that allows this process to go just via nitrite, instead of nitrate, to nitrogen gas. This would significantly reduce oxygen and/or carbon requirement in nitrogen removal. If successful, the new operating method will allow modern wastewater treatment plants to achieve a better effluent quality at lower costs.Read moreRead less
Production, Fate and Transport of Cyanobacterial Toxins in Waterways. Australian waterways are under severe pressure from both large variation in precipitation patterns and various sources of contamination. In particular, the management of algal blooms costs Australians hundreds of millions of dollars a year. Through the use of a unique approach this project will provide the necessary information for a science based decision making strategies to eradicate, as much as possible, algal blooms and ....Production, Fate and Transport of Cyanobacterial Toxins in Waterways. Australian waterways are under severe pressure from both large variation in precipitation patterns and various sources of contamination. In particular, the management of algal blooms costs Australians hundreds of millions of dollars a year. Through the use of a unique approach this project will provide the necessary information for a science based decision making strategies to eradicate, as much as possible, algal blooms and to reduce the risk of severe injuries to the public, livestock and the environment, resulting from contamination waterways by algal toxins.

Understanding Fugitive Greenhouse Gas Emissions from Wastewater Systems for Reliable Accounting and Effective Mitigation. Climate change caused by greenhouse gas (GHG) emissions is one of the most serious challenges facing mankind. Substantial reductions in emissions must be achieved, with responsibility shared by all industrial sectors. Wastewater systems contribute to GHG emission through not only energy consumption but also direct emissions of fugitive GHG such as methane and nitrous oxide.

Climate change caused by greenhouse gas (GHG) emissions is one of the most serious challenges facing mankind. Substantial reductions in emissions must be achieved, with responsibility shared by all industrial sectors. Wastewater systems contribute to GHG emission through not only energy consumption but also direct emissions of fugitive GHG such as methane and nitrous oxide. This project aims to deliver the urgently needed knowledge and technology support to the Australian wastewater industry to achieve reductions in fugitive emissions. The research will also provide support to the greenhouse office via more reliable estimation of such emissions.Read moreRead less
Optimal management of corrosion and odour problems in sewer systems. Pollutants in wastewater undergo complex changes in sewers, leading to the production and release of odorous and corrosive compounds. Despite major efforts and expenditure by water utilities to mitigate these problems, odorous emissions from sewers are still commonly occurring in urban areas. Furthermore, the value of public assets is significantly diminished due to sewer corrosion, costing hundreds of millions of dollars a yea ....Optimal management of corrosion and odour problems in sewer systems. Pollutants in wastewater undergo complex changes in sewers, leading to the production and release of odorous and corrosive compounds. Despite major efforts and expenditure by water utilities to mitigate these problems, odorous emissions from sewers are still commonly occurring in urban areas. Furthermore, the value of public assets is significantly diminished due to sewer corrosion, costing hundreds of millions of dollars a year in Australia alone. This project is a major joint effort by the Australian water industry and world-leading scientists to generate advanced knowledge and develop effective technologies for optimal odour and corrosion management in sewers, delivering large social, environmental and economic benefits.Read moreRead less

Methane and nitrous oxide emissions from sewers – understanding, modelling and mitigation. The research and industry partners will collaborate on this project to quantify, understand and mitigate emissions of methane and nitrous oxide in sewer networks. Both methane and nitrous oxide are potent greenhouse gases, and their emissions need to be accounted for and mitigated for the water industry to achieve greenhouse neutral water services.
