Summary
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.

This project aims to develop state-of-the-art conceptual and numerical models of river-soil-groundwater interactions to address complex and persistent questions on water sustainability in the Lower Burdekin Delta, Queensland, where groundwater pumping to irrigate sugarcane has been supplemented by artificial recharge for over 50 years. This project expects to deliver new knowledge of critical aquifer processes to inform the scheme operation, the largest in the country. Expected outcomes include ground-breaking management plans for the aquifer-replenishment scheme. Anticipated benefits involve balancing the needs of agriculture and the protection of pristine environments, including groundwater discharge to the Great Barrier Reef.

A new strategy for design flood estimation in a nonstationary climate. Evidence suggests that global warming will result in an increase in the frequency and/or magnitude of heavy rainfall, leading to flooding with potentially devastating consequences. This study provides a renewed focus on design flood estimation that takes into account a changing climate where assumptions of stationarity are no longer tenable.
Towards an Active and Passive L- and P-band soil moisture satellite mission. This project tests alternate configurations for remote sensing of soil moisture using a new state-of-the-art Active/Passive (ie radar/radiometer) P-/L-band (ie microwave) satellite concept through a series of airborne field experiments. Timely soil moisture information is critical to improved water management for food production in the face of climate variability. The challenge is to do this accurately over large areas ....Towards an Active and Passive L- and P-band soil moisture satellite mission. This project tests alternate configurations for remote sensing of soil moisture using a new state-of-the-art Active/Passive (ie radar/radiometer) P-/L-band (ie microwave) satellite concept through a series of airborne field experiments. Timely soil moisture information is critical to improved water management for food production in the face of climate variability. The challenge is to do this accurately over large areas with an appropriate spatio-temporal detail, and for a soil depth that closely approximates the layer which impacts crop/pasture growth and influences management decisions. The longer P-band allows deeper penetration into the soil while the active/passive combination uses the respective resolution and accuracy characteristics.Read moreRead less
Water, carbon, and economics: resolving complex linkages for river health. By linking landscapes into our emerging low-carbon economy, this project will investigate how land management practices can be improved through payments for ecosystem services. With a focus on water and carbon, the main goal is to develop mechanisms to support integrated land and water management at the catchment scale.

Summary
A stable-isotope mass spectrometer for novel determinations of past temperatures. Much of the Australian landscape is subject to a dry and evaporative climate, making it very difficult to use conventional geochemical techniques to estimate past temperatures, even on short timescales of tens to hundreds of years. The application of a new isotopic technique to preserved carbonate minerals (soil carbonate, shells in rivers, lakes and the ocean) avoids the difficulty of this variable evaporation, an ....A stable-isotope mass spectrometer for novel determinations of past temperatures. Much of the Australian landscape is subject to a dry and evaporative climate, making it very difficult to use conventional geochemical techniques to estimate past temperatures, even on short timescales of tens to hundreds of years. The application of a new isotopic technique to preserved carbonate minerals (soil carbonate, shells in rivers, lakes and the ocean) avoids the difficulty of this variable evaporation, and directly measures past temperatures. This will have a profound effect on our understanding of environmental changes on both short and long time scales, and permit a better understanding of the hydrological balances within the landscape.Read moreRead less

This project aims to deliver an accurate and reliable seasonal streamflow forecasting system for Australian water users by developing a flexible rainfall-runoff modelling approach integrated into a Bayesian inference and prediction framework. These scientific developments aim to significantly advance the operational capabilities of the Australian Bureau of Meteorology to deliver robust streamflow forecasts to water agencies such as South East Queensland Water and others across Australia. Accurate predictions of future water flows are of tremendous value to urban and rural Australian communities whose economic prosperity, water security and social well-being depend on reliable estimates of water availability.Read moreRead less
Hydrogeological drivers and fate of spring flow in a semi-arid setting. In arid and semi-arid climates, aquatic and terrestrial ecosystems often rely on groundwater springs. Spring hydrology depends on complex relationships between underlying aquifers and surface conditions, leading to high uncertainties in understanding aquifer-spring-wetland hydrology, which is critical for spring ecosystem protection and to inform management of relevant groundwater-affecting activities. This project will appl ....Hydrogeological drivers and fate of spring flow in a semi-arid setting.

Spring hydrology depends on complex relationships between underlying aquifers and surface conditions, leading to high uncertainties in understanding aquifer-spring-wetland hydrology, which is critical for spring ecosystem protection and to inform management of relevant groundwater-affecting activities. This project will apply novel hydrogeophysical and hydrochemical methods, and computer modelling, to investigate the source aquifer of, and fate of discharge from the Doongmabulla Springs Complex (DSC), located in an area of future development. Project results will inform spring vulnerability to development pressures and climate effects.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
