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
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
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. The technology developed here will be applicable throughout Australia and can be exported overseas, especially to south-east Asia.Read moreRead less

The project will integrate a complex set of functions into one landscape restoration design which will benefit production and conservation objectives. These functions are improved use of surface runoff using native vegetation to reduce velocities and increase infiltration, improved soil and catchment condition through decreased erosion, lowering wind speeds which desiccate landscape and erode valuable topsoil, providing a system of corridors for biodiversity, and sequestering carbon in woody biomass. IVB’s configuration captures the beneficial structural and functional attributes of vegetation while minimising competitive interactions. This will increase the resilience and productivity of Australian farming landscapes in a changing climate.Read moreRead less

The Australian water industry faces the challenge of catering for the potable water demand of a rapidly expanding population with reduced reliability on supply imposed by an increasingly variable climate. Diversified water supply schemes (DWSS) incorporating decentralised systems or reuse sources are touted as a means to handle the inherent weaknesses of centralised urban water supply schemes by potentially drawing 30-50 per cent less demand on their reserves. This research study will provide evidence to support the implementation of best practice DWSS based on an evidence based holistic assessment of their performance considering potable water savings, capital and operation costs, energy demand, as well as environmental and community impacts.Read moreRead less
