New research investigates how to include future environmental change in water runoff models

For a long time, river modellers have faced the challenges of tracking water movement across landscapes. This task becomes more complex when different river catchments use different models. Along with jurisdictions, we are in the process of improving these systems and tools.

The MDBA is partnering with states to create new river modelling roles, enhancing capability and building a deeper understanding of the Basin.

Sustainable diversion limits are how much water, on average, can be used in the Basin by towns and communities, farmers and industries.

We're using the best available science and knowledge to help deliver a productive and healthy future for the interconnected rivers of the Murray–Darling Basin.

In 2012 the Basin Plan listed estimates of the average annual volumes of floodplain harvesting as components of the baseline diversion limit (BDL) in some northern Basin sustainable diversion limit (SDL) resource units. The New South Wales ‘Healthy Floodplains Project’ includes work to enable calculation of re-estimates of BDLs associated with floodplain harvesting in these northern New South Wales SDL resource units. These volumes will contribute to re-estimates of the total BDLs for all forms of take.

This is a review of the hydrological models that underpin the Barwon-Darling Watercourse water resource plan that was submitted to the Murray–Darling Basin Authority in June 2020. The 2 most important of these models were the Baseline Diversion Limit model and the Annual Permitted Take model. This review was prepared to assist the Murray–Darling Basin Authority in their appraisal of the Barwon-Darling Watercourse water resource plan prior to its accreditation and implementation under the Basin Plan.

The MDBA was at the Riverina Field Days recently to share with, and learn from, the local community.

The River Murray Water Quality Monitoring Program has captured physical and chemical data from 28 River Murray and tributary sites since 1978. This report examines long-term trends in water quality and drivers of change.

Along with our river management partners, we use a variety of models to support the planning and running of the Murray–Darling Basin’s rivers.
