This project aims to develop, implement and evaluate a field monitoring technique building upon new theoretical developments to quantify evaporation and transpiration from soil and vegetation using a limited number of measurements of temperature, humidity and net radiation above soil and canopies. This new technique aims to characterise in situ the effect of vegetation cover on the partitioning of energy and water fluxes in areas with complex terrain and patchy vegetation. The project aims to produce new field experiment designs for optimal use of available technology and without restrictive limitations of fetch size required by traditional approaches (for example, eddy-covariance, Bowen ratio method).Read moreRead less

Australian national facility for noble-gas radio-isotope measurements:
This facility is designed to provide researchers with the ability to accurately date water and ice cores using the natural radio-isotopes in the sample. Radiocarbon dating has been a revolutionary tool in providing answers to a range of questions in anthropology, archaeology and the earth sciences. However, radiocarbon dating has a strong limitation in that it can only date periods from 1000–50 000 years: the use of radioactive noble-gas isotopes can extend this range out to 1 year to 1 million years. This capability in the new facility is expected to support new understanding of processes in artesian reservoirs, ocean currents and geology that may affect questions of water availability, climate and environmental change.Read moreRead less
A new flood design methodology for a variable and changing climate. The extreme temporal and spatial variability of Australia's rainfall affects the quantity and quality of water resources, the productivity of agricultural systems, and aquatic and terrestrial ecosystems. Given the impact of extreme events such as floods and the massive investment in water-related infrastructure, evaluation of these risks is an issue of national economic and environmental significance.

The extreme temporal and spatial variability of Australia's rainfall affects the quantity and quality of water resources, the productivity of agricultural systems, and aquatic and terrestrial ecosystems. Given the impact of extreme events such as floods and the massive investment in water-related infrastructure, evaluation of these risks is an issue of national economic and environmental significance. Monte Carlo simulation techniques will quantify the risks associated with current and future climate change, and the combined risks that come from multiple sources, such as from coastal tides and storm runoff. This research will provide a new spatial framework for calculating risk as well as tools to evaluate flood risk.Read moreRead less

There is a rapidly increasing demand for a range of environmental data. For example, information on soil moisture status is required for efficient and sustainable water use. Moreover, irrigation practices and large scale clearing have led to serious land degradation through increased salinity from rising water tables. Combined soil moisture and salinity measurement will provide important insight to this complex issue. Further, understanding the complex and rich biodiversity of Australian flora and its adaptation to droughts and fire is essential to ensuring Australian ecosystem longevity. Knowledge of flora changes through time as a function of soil moisture content and salinity is key to gaining this understanding.Read moreRead less

Groundwater and the Environment: Understanding the role of groundwater in the maintenance of sustainable ecosystems in Australia.
. 97% of freshwater on earth is groundwater. Despite this, it is undervalued, largely unexplored and poorly understood. In Australia, groundwater plays a critical role in our salinity problem and sustains our ecosystems. It will be a critical water supply in the future, especially in times of drought when surface water is scarce. Our nation's groundwater resources ....Groundwater and the Environment: Understanding the role of groundwater in the maintenance of sustainable ecosystems in Australia.
. 97% of freshwater on earth is groundwater. Despite this, it is undervalued, largely unexplored and poorly understood. In Australia, groundwater plays a critical role in our salinity problem and sustains our ecosystems. It will be a critical water supply in the future, especially in times of drought when surface water is scarce. Our nation's groundwater resources require the same unresounding commitment to preservation that we now see in the Murray-Darling basin. This network develops foundations for a desperately needed National Groundwater Centre to provide research to ensure win-win outcomes for this country's water resources and the users that rely on them.

An integrated modelling approach for efficient management of irrigated landscapes. Northern Victoria's irrigators use a substantial portion of water from the Murray-Darling Basin, which is under mounting pressure to satisfy competing economic, social and environmental needs for water in the face of climate change. Up to 20 per cent of this water may be on-farm surface runoff and deep percolation, with poorly known spatial distributions. This project will provide reliable temporally and spatially ....An integrated modelling approach for efficient management of irrigated landscapes. Northern Victoria's irrigators use a substantial portion of water from the Murray-Darling Basin, which is under mounting pressure to satisfy competing economic, social and environmental needs for water in the face of climate change. Up to 20 per cent of this water may be on-farm surface runoff and deep percolation, with poorly known spatial distributions. This project will provide reliable temporally and spatially distributed information on surface runoff and deep percolation for Northern Victoria irrigation regions. This will inform decisions which improve water use efficiency, agricultural productivity and environmental values through optimisation of irrigation infrastructure and by better management of groundwater resources and salinity.Read moreRead less
