This research will (a) provide guidance on future adaptations of stormwater quality infrastructure, (b) provide better scientific understanding of pollutant movements in urban systems and (c) provide methodology to 'future proof' infrastructure design against the pressures of climate change and urban population growth. Project outputs will (a) enable water-sensitive urban designs to be applied reliably and (b) minimise the cost of re-building assets before the end of their design life due to climate change. The ultimate benefit is the reduction in water pollution from roadways leading to improved human and ecosystem well-being of urban communities.Read moreRead less
Traffic microsimulation of ITS implementations in CBD road networks. This research project will investigate the advantages and disadvantages of using Intelligent Transport Systems (ITS) technologies in an Australian Central Business District (CBD) environment. It is often assumed that road networks and especially high activity areas such as CBDs can benefit significantly from ITS implementations. Traditionally ITS impacts have been difficult to quantify due to difficulties in isolating network ....Traffic microsimulation of ITS implementations in CBD road networks. This research project will investigate the advantages and disadvantages of using Intelligent Transport Systems (ITS) technologies in an Australian Central Business District (CBD) environment. It is often assumed that road networks and especially high activity areas such as CBDs can benefit significantly from ITS implementations. Traditionally ITS impacts have been difficult to quantify due to difficulties in isolating network effects and limitations with traditional traffic models. The project will overcome this difficulty by using a current state of the art traffic microsimulation model in order to test various ITS scenarios in a duplicate of a real world CBD.Read moreRead less
Derivation of Emissions Models for Commercial Vehicles. This research project will develop emissions models for commercial vehicles that are capable of modelling changes in driver behaviour. Second by second emissions data from certification tests will be disaggregated into their component phases of acceleration, cruise, deceleration and idle. The emissions characteristics of these phases will be established and analysed to produce empirical models of emissions per unit time versus mode of opera ....Derivation of Emissions Models for Commercial Vehicles. This research project will develop emissions models for commercial vehicles that are capable of modelling changes in driver behaviour. Second by second emissions data from certification tests will be disaggregated into their component phases of acceleration, cruise, deceleration and idle. The emissions characteristics of these phases will be established and analysed to produce empirical models of emissions per unit time versus mode of operation. These models will then be able to describe the changes in emission characteristics under different commercial vehicle operating modes for a range of commercial vehicle types.Read moreRead less

Advancing water pollution emissions modelling in cities of the future. Advancing water pollution emissions modelling in cities of the future. This project aims to advance stormwater pollution modelling and enhance its link with urban development. Management of stormwater pollution by industry often results in inadequate strategies and, crucially, sub-optimal financial investments.

Advancing water pollution emissions modelling in cities of the future. This project aims to advance stormwater pollution modelling and enhance its link with urban development. Management of stormwater pollution by industry often results in inadequate strategies and, crucially, sub-optimal financial investments. Since this is unlikely to improve in light of urban growth and climate change, addressing decade-old pollution modelling knowledge gaps and the lack of a multidisciplinary approach to stormwater pollution management is urgent. The anticipated outcome is a modelling tool which industry can use to manage stormwater pollution in changing cities through smarter and economic technology and policy.Read moreRead less
Sources, sinks and processes of faecal contamination in urban estuaries: a case study of the lower Yarra River estuary. The Yarra River estuary is highly contaminated with faecal pollution, reducing the useability of Melbourne’s most iconic feature. This project will provide the necessary understanding to help mitigate faecal sources, with the ultimate aim of reducing the risks to users of this estuary.
Robust streamflow predictions by improving the identification of hydrological model structure. This project aims to provide Australian environmental agencies, design engineers and policy-makers with robust methods that better utilise observed environmental data and process understanding to produce hydrological models with stronger scientific basis and improved operational predictive ability in gauged and ungauged catchments.
Fate of engineered nanoparticles: Challenges in informing human and ecological health risk assessments. Engineered nanoparticles (ENPs) have generated significant public and scientific excitement due to their unique properties. This has led to their application in a wide variety of industries (for example, in composite materials and drug delivery). However, there is concern that some ENPs can have detrimental environmental impacts. This project aims to quantify, for the first time, the fate of E ....Fate of engineered nanoparticles: Challenges in informing human and ecological health risk assessments. Engineered nanoparticles (ENPs) have generated significant public and scientific excitement due to their unique properties. This has led to their application in a wide variety of industries (for example, in composite materials and drug delivery). However, there is concern that some ENPs can have detrimental environmental impacts. This project aims to quantify, for the first time, the fate of ENPs that have leached out of commercial products in groundwater systems. This information is expected to assist regulators in developing appropriate legislation to balance the tremendous benefits and potential risks of nanotechnology.Read moreRead less
Optimum aeration strategies for shallow tidally flushed lakes. Shallow tidally flushed lakes frequently suffer from water quality problems which include catastrophic fish kills. Frequently these events are related to the response of a highly modified system to a natural event. One event is the change from a saline to a fresh environment with seasonal freshwater inflow, in which case the salt tolerant algal species dies. The balance between photosynthesis, sediment uptake, surface oxygen transfer ....Optimum aeration strategies for shallow tidally flushed lakes. Shallow tidally flushed lakes frequently suffer from water quality problems which include catastrophic fish kills. Frequently these events are related to the response of a highly modified system to a natural event. One event is the change from a saline to a fresh environment with seasonal freshwater inflow, in which case the salt tolerant algal species dies. The balance between photosynthesis, sediment uptake, surface oxygen transfer and flushing is lost, with the result that the lake quickly becomes anoxic, resulting in fish kills. This project examines some aeration solutions to this problem.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
