Gwydir Valley Daily River Flow Model Outputs

Historic daily flow rates in megalitres per day for the Gwydir Valley river systems in New South Wales, Australia. The data is produced by the NSW Department of Climate Change, Energy, the Environment and Water using the best available hydrologic models at the time of publishing. Individual files correspond to specific river gauges and the dataset is expected to be updated annually.

Use Cases

• Calibrate hydrological models based on the long-term historic flow series.
• Analyze trends in river flow rates over the historic climate period.
• Assess water availability for environmental or agricultural studies using modelled gauge data.

Strengths

• Time series spans a historic period from the early to mid-1890s up to the water year prior to publication.
• Data is modelled using the best available hydrologic models at the time of publishing.
• Files are organized by specific river gauge number and name for targeted analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the NSW river systems.
