This research aims at developing and validating an air quality assessment model that would enable predictions of air quality in various mircoenvironments for the purpose of exposure and risk assessment, housing and urban planning, and policy setting. This research will provide scientific foundation and a tool for developing future directions for management and control to protect the community and the environment.Read moreRead less
Restoring hydrological connectivity of surface and ground waters: Biogeochemical processes and environmental benefits for river landscapes. This project examines the restoration of lateral hydrological connectivity to improve floodplain structure and function. The connections between stream flows and both shallow groundwaters and floodplains are critical in sustaining river landscapes. Degrading land and water management practices compounded by natural climatic extremes have severed this link. ....Restoring hydrological connectivity of surface and ground waters: Biogeochemical processes and environmental benefits for river landscapes. This project examines the restoration of lateral hydrological connectivity to improve floodplain structure and function. The connections between stream flows and both shallow groundwaters and floodplains are critical in sustaining river landscapes. Degrading land and water management practices compounded by natural climatic extremes have severed this link. Restoring hydrological connectivity is vital for replenishing groundwater storage and increasing base flows that affect fundamental riverine processes. Using an innovative approach to sustainable agriculture, our project unites multidisciplinary scientific and industry expertise to investigate the biogeochemical and biophysical effects of secondary floodplain channels and in-stream structures on riverine groundwater processes.Read moreRead less

The project is proposed and supported by the National Environment and Heritage Protection Council, who will be reviewing Australian air quality standards from 2005. The study aims to determine whether current air quality standards adequately protect the health of Australian school children, and to provide nationally-based information to inform any changes to the current standards. A cross-sectional study will examine cumulative effects; a nested panel study will quantify day-to-day effects of air pollution in sensitive children. Sampling will ensure national representation and generalisability of findings. This will be the first nationally-based study of the relationship between air quality and child health in Australia.Read moreRead less
Drains in acid sulfate soils: behaviour and management for optimal water quality. Water draining from acid sulfate soil (ASS) into rivers via drains is often severely polluted, resulting in massive fish kills and chronic environmental and economic damage. Effective drain management techniques to minimise the export of acidity and deoxygenating drain oozes will be developed. The basic processes that affect hydraulic functioning, acidity and toxic drain ooze export in ASS drainage systems will be ....Drains in acid sulfate soils: behaviour and management for optimal water quality. Water draining from acid sulfate soil (ASS) into rivers via drains is often severely polluted, resulting in massive fish kills and chronic environmental and economic damage. Effective drain management techniques to minimise the export of acidity and deoxygenating drain oozes will be developed. The basic processes that affect hydraulic functioning, acidity and toxic drain ooze export in ASS drainage systems will be addressed. This project will provide the basis for the environmentally sound management of these drains.

Access to safe drinking water is essential for the economic and social development of Australia. There is increasing interest in applying advanced water treatment processes, such as membrane filtration or ozonation, to treat secondary effluent to a potable standard. This project promotes improved organic pollutant removal and monitoring during advanced water treatment and will contribute to the National Research Priority goal, water - a critical resource, by providing the increased protection of receiving waters including rivers and seawater. Further, as very few studies consider the role of dissolved organic matter for organic pollutant fate in water reuse internationally, this project will help to advance Australia's position in science.Read moreRead less
Impacts of deforestation and afforestation on greenhouse gas emissions, and carbon and water resources in the Daly River catchment, north Australia. Over the last decade, north Australia have been viewed as a potentially exploitable resource, given issues of salinisation, soil acidification, over-allocation of water resources and rainfall declines in south Australian agricultural regions. Improved pastures and plantation forestry are two land uses that may expand in the NT. Clearing of savanna v ....Impacts of deforestation and afforestation on greenhouse gas emissions, and carbon and water resources in the Daly River catchment, north Australia. Over the last decade, north Australia have been viewed as a potentially exploitable resource, given issues of salinisation, soil acidification, over-allocation of water resources and rainfall declines in south Australian agricultural regions. Improved pastures and plantation forestry are two land uses that may expand in the NT. Clearing of savanna vegetation would be required, with implications for greenhouse gas emissions, soil health, water resources and dry season environmental flows. This project will track greenhouse emissions and water use from uncleared and cleared savanna that has been converted to pasture and timber plantations, providing critical understanding of the environmental implication of such land use change in savanna.Read moreRead less

Poor water quality affects many rivers and receiving waters such as the Great Barrier Reef and Gippsland Lakes. This project aims to use Bayesian hierarchical models of statewide water quality data to quantify the effects of a range of factors on stream water quality including climate, land use, river flow, vegetation cover, etcetera. The analysis intends to extract information from the entire data set rather than concentrating on individual sites. It intends to underpin a new predictive capacity including response to land use and management changes and climatic variations based on long-term data sets, as well as a water quality prediction capability. It is intended that the models developed will jointly model a range of inter-related water quality parameters.Read moreRead less
