💧 New Open Data Release: Water Models – Without Development – Namoi

We’re pleased to announce the release of a new hydrological model on the SEED Open Data Portal: Water Models – Without Development – Namoi

This dataset provides a “without development” representation of the Namoi River system — a model that excludes water infrastructure (dams, weirs), extraction, and management rules. It captures natural processes such as:

• Headwater and residual catchment runoff
• River reach flow routing
• Transmission losses

The model is derived from a full system model, calibrated using observed data, and supports transparent and evidence-based water policy.

📍 Geographic Extent:
The Namoi River model includes tributaries like the Manilla, Peel, Mooki Rivers, and extends downstream to the Barwon River at Dangar Bridge.

📘 More details:

• Model timestep: Daily
• Input data period: 2 December 1891 – 8 July 2024
• Source version: 5.20.0
• Climate input: SILO
• Runoff data: Calibrated Sacramento rainfall-runoff models
• Gauge and reach details: Included in the dataset

Note: Source software (available from ewater.org.au) is required to view and run the model(s) within.

📌 Why it matters:
These models are essential foundations of water planning and policy, and their public release supports greater transparency, accountability, and reuse across research and management.

This release joins existing Without Development model datasets for the Peel, Castlereagh, Richmond, Lachlan, Macquarie, and Gwydir catchments — all available via the SEED portal.
