Hydrologic Modelling of Connectivity Expert Panel Recommendations (2025)
We’re pleased to share a new collection of hydrologic modelling outputs that support the assessment of the Connectivity Expert Panel recommendations for improving river connectivity in the northern Murray–Darling Basin.
We’re pleased to share a new collection of hydrologic modelling outputs that support the assessment of the Connectivity Expert Panel recommendations for improving river connectivity in the northern Murray–Darling Basin.
This work forms part of a broader program investigating how different water management approaches may influence flows, connectivity, and outcomes across the Barwon–Darling River system in dry and non-dry periods. The modelling provides evidence to help understand potential hydrologic, environmental, and economic impacts under a range of scenarios.
The modelling has been completed using the latest approved versions of the models and includes a base case for comparison.
What’s included
This collection is comprised of six hydrologic modelling scenarios, each representing a different approach to achieving the Panel’s objectives.
Each scenario contains the modelling outputs and supporting documentation for that approach.
Explore the modelling scenarios
- Scenario 1 – End of System – High Security Accounts
- Scenario 2 – End of System – Translucency
- Scenario 3 – Extended Resumption of Flow
- Scenario 4 – Connectivity EWA – Dam Inflow Trigger
- Scenario 5 – Connectivity EWA – Bourke Flow Trigger
- Scenario 6 – Combination (Extended Resumption of Flow, End of System – Translucency, and Connectivity EWA – Bourke Flow)
For each scenario, the hydrologic modelling provides information on:
- changes in flows at gauges relative to the base case
- changes in water that can be extracted by each licence type relative to the base case
