Improving water quality modelling by better understanding solute transport. Poor stream water quality is a critical problem in Australia and globally. Stream water quality depends directly on pathways and time taken for water to transport pollutants through catchments. Predicting these pathways is highly challenging and currently requires specialised data. This project aims to better model the movement of water from rainfall to streams, enable greatly improved use of water quality data routinely ....Improving water quality modelling by better understanding solute transport. Poor stream water quality is a critical problem in Australia and globally. Stream water quality depends directly on pathways and time taken for water to transport pollutants through catchments. Predicting these pathways is highly challenging and currently requires specialised data. This project aims to better model the movement of water from rainfall to streams, enable greatly improved use of water quality data routinely collected in Australia's catchments and thereby better predict water quality behaviour. Proposed field studies aim to support this development. The outcomes sought are improved planning and management of water quality in our rivers, lakes and estuaries, improved health of these water bodies and improved water supplies.Read moreRead less
Efffective Management of Water Resources in Semiarid Regions Using Remote Sensing. Due to the vast expense and difficulties to access many areas from the ground, there is currently no effective system for assessing and managing water resources over many large semi-arid regions of the world. Through the study of two complementary Basins - The Murray and Lake Chad Basins - we propose a new approach based on satellite imagery to provide regular and detailed information on the state of our water res ....Efffective Management of Water Resources in Semiarid Regions Using Remote Sensing. Due to the vast expense and difficulties to access many areas from the ground, there is currently no effective system for assessing and managing water resources over many large semi-arid regions of the world. Through the study of two complementary Basins - The Murray and Lake Chad Basins - we propose a new approach based on satellite imagery to provide regular and detailed information on the state of our water resources in these areas. These innovative techniques will yield new information on critical water issues: water availability, salinity, groundwater/surface water interactions, climate and land use change impact. This project provides the basis for sustainable water use in regional Australia.Read moreRead less
Satellite based monitoring system of lakes and wetlands water quality. Effectively managing water resources within Australia is critical for social and economic growth. The large-scale of Australian catchments means that many lakes are unmonitored due to time and costs required for on-ground programs. This research project directly addresses the lack of observations. Information on water quality from satellite, on-ground, and modeling investigations are integrated to develop an operational moni ....Satellite based monitoring system of lakes and wetlands water quality. Effectively managing water resources within Australia is critical for social and economic growth. The large-scale of Australian catchments means that many lakes are unmonitored due to time and costs required for on-ground programs. This research project directly addresses the lack of observations. Information on water quality from satellite, on-ground, and modeling investigations are integrated to develop an operational monitoring system for surface water quality. Results are used to model the sensitivity of the water quality to changes in climate and land use. The monitoring system can be used to protect catchment assets by risk assessment and provide insights into management scenarios.Read moreRead less
Quantifying near-surface diffuse discharge from the southwest Great Artesian Basin. Groundwater from the Great Artesian Basin (GAB) supplies one of Australia's largest mining operations and many pastoral enterprises. The GAB is the only significant water resource through much of arid central Australia and supports unique environmental values in this region. This project will provide vital data on natural, near-surface leakage rates from the GAB that can be used to gain a greater understanding of ....Quantifying near-surface diffuse discharge from the southwest Great Artesian Basin. Groundwater from the Great Artesian Basin (GAB) supplies one of Australia's largest mining operations and many pastoral enterprises. The GAB is the only significant water resource through much of arid central Australia and supports unique environmental values in this region. This project will provide vital data on natural, near-surface leakage rates from the GAB that can be used to gain a greater understanding of the amount of water available for sustainable extraction. This will assist in the improved management of the GAB resource and in doing so contribute to greater certainty for the mining and pastoral users of the GAB groundwater and provide greater protection for unique ecosystems associated with natural discharge springs.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.

Surface-ground water interactions and increasing salinity in the upper Hunter River. Australia's first salinity trading scheme, to limit impacts of industrial saline wastewater discharges, operates in the Hunter Region, NSW. Despite it, a recent audit suggests stream salinity levels will continue to rise over the next century. No assessment tools are available to identify causes of salinity increases in sub-catchments of the Hunter. This severely limits rehabilitation strategies aimed at address ....Surface-ground water interactions and increasing salinity in the upper Hunter River. Australia's first salinity trading scheme, to limit impacts of industrial saline wastewater discharges, operates in the Hunter Region, NSW. Despite it, a recent audit suggests stream salinity levels will continue to rise over the next century. No assessment tools are available to identify causes of salinity increases in sub-catchments of the Hunter. This severely limits rehabilitation strategies aimed at addressing river salinity. Current rehabilitation focuses on revegetation of recharge and discharge areas, with limited understanding of the primary local drivers for salinity, and without assessment of whether rehabilitation is addressing or exacerbating problems. This project aims to supply that understanding.Read moreRead less
Connected Water in Semi Arid Environments. Water is undoubtedly our most valuable resource, and continued economic and social development is critically dependant on water resources. Ephemeral rivers in semi-arid areas that lie above the water table commonly recharge the underlying aquifers. In much of the Murray Basin of southeast Australia, river recharge has provided rare fresh groundwater that is both a potential source of water for irrigation and domestic supply and a buffer to saline region ....Connected Water in Semi Arid Environments. Water is undoubtedly our most valuable resource, and continued economic and social development is critically dependant on water resources. Ephemeral rivers in semi-arid areas that lie above the water table commonly recharge the underlying aquifers. In much of the Murray Basin of southeast Australia, river recharge has provided rare fresh groundwater that is both a potential source of water for irrigation and domestic supply and a buffer to saline regional groundwater entering the rivers as baseflow. This project will allow the risk to these groundwater lenses from landuse changes and river regulation to be quantified as well as constraining whether the water resources may be used sustainably.

A new paradigm for catchment management: detection, forecasting and management of water catchments with multiple steady states. Understanding the response and recovery of Australia's water catchments to climatic change and variability is become increasingly urgent. Our catchments are vulnerable because there is a fundamental gap in our understanding of how they recover from high or low rainfall periods. This project will: a) advance water management concepts; b) build tools to understand how and ....A new paradigm for catchment management: detection, forecasting and management of water catchments with multiple steady states. Understanding the response and recovery of Australia's water catchments to climatic change and variability is become increasingly urgent. Our catchments are vulnerable because there is a fundamental gap in our understanding of how they recover from high or low rainfall periods. This project will: a) advance water management concepts; b) build tools to understand how and when catchments might switch to new states when hit by a disturbance; and c) identify how best to build the buffering capacity to reduce the chance of a switch occurring. The project will make Australia's groundwater and streamflow resources more secure and make Australian researchers and water resource managers world leaders in the emerging science of catchment resilience.Read moreRead less
Integration of Surface Water and Ground Water Processes in Coastal Catchments. The hydrologic processes which describe surface water and groundwater movement often occur at completely different temporal and spatial scales. These two distinct flow regimes, however, are intrinsically coupled in coastal catchments in Australia. The superposition of local flow systems on a regional groundwater framework results in complex interactions which are difficult to accurately predict with existing numeric ....Integration of Surface Water and Ground Water Processes in Coastal Catchments. The hydrologic processes which describe surface water and groundwater movement often occur at completely different temporal and spatial scales. These two distinct flow regimes, however, are intrinsically coupled in coastal catchments in Australia. The superposition of local flow systems on a regional groundwater framework results in complex interactions which are difficult to accurately predict with existing numerical models, and are not truly understood even at the conceptual level. This work aims to study a single catchment at a very detailed level to allow for the production of a new integrated approach to the simulation of the complete hydrologic systemRead moreRead less
Salinity processes in Lake Eyre Basin rivers. The unregulated rivers of the Lake Eyre Basin (LEB) provide a unique opportunity to study natural salinisation processes at multiple scales, in systems that have hydrological and biological similarities with dryland rivers in the Murray Darling Basin (MDB) and elsewhere. The rivers of the LEB maintain a high quality of ecological health despite salinity levels that can vary over two orders of magnitude with changing flow conditions.

The unregulated rivers of the Lake Eyre Basin (LEB) provide a unique opportunity to study natural salinisation processes at multiple scales, in systems that have hydrological and biological similarities with dryland rivers in the Murray Darling Basin (MDB) and elsewhere. The rivers of the LEB maintain a high quality of ecological health despite salinity levels that can vary over two orders of magnitude with changing flow conditions. This project will study salinity processes in the unregulated rivers of LEB and identify the dynamics of stream salinity using a combination of novel tracer and hydrological measurements and modelling.Read moreRead less
