Two science projects are helping the Tasmanian State Government to use scientific evidence for responsible water management across the state.
The Catchment Yield Science Update Project and the Groundwater Assessment Project are being delivered as part of the Rural Water Use Strategy.
Minister for Primary Industries and Water Jo Palmer said these projects would help to ensure that Tasmania’s freshwater resources can support various uses and the environment during changing conditions, as well as fostering innovation and growth.
“Water security plays a critical role in supporting the Tasmanian State Government’s Agri-Food Plan and target to sustainably grow the farmgate value of agricultural production to $10 billion by 2050,” Minister Palmer said. “These projects will provide us with the data we need to make science-based decisions to guide the delivery of the Rural Water Use Strategy.”
The Catchment Yield Science Update Project will keep Tasmania’s surface water yield estimates current and reliable by incorporating the latest climate data into the State’s hydrological models.
Working with a hydrology specialist, WMAwater, the Department of Natural Resources and Environment Tasmania (NRE Tas) has conducted preliminary testing of four climate datasets for six catchment hydrological models.
Based on the findings, a research report has been prepared to guide the integration of new climate predictions into statewide models and can be viewed on the NRE Tas.
Using science to improve water management
The Groundwater Assessment Project focuses on improving the understanding of risks and opportunities related to groundwater use, as well as the connections between surface water and groundwater.
Minister Palmer said the first phase of the project has produced a Groundwater Risk Assessment Tool and Management Framework.
“This has introduced a comprehensive and standardised approach to assessing groundwater resource risks in Tasmania,” Minister Palmer said. “Field studies in areas with high groundwater risks will be conducted to confirm the severity of these risks and inform future management strategies.”

Both projects are being delivered in partnership with the Australian Government, with funding provided through the National Water Grid Science Program.
