Water Modelling-Modelled Data-Long-term average annual extraction limit (LTAAEL)-Barwon-Da

NSW, Australia, provides modelled water flow data for the Barwon-Darling river system to assess compliance with Long-term Average Annual Extraction Limits (LTAAEL). The dataset contains flows at several gauges simulated by an annually extended LTAAEL model, representing conditions under Water Sharing Plan rules. It is published by the NSW Department of Climate Change, Energy, the Environment and Water, with outcomes updated annually.

Use Cases

• Assess regulatory compliance by comparing modelled LTAAEL with modelled long-term average annual extractions.
• Analyze river system sustainability under Water Sharing Plan development and management rules.
• Compare simulated flow scenarios, such as against Annual Permitted Take (APT) or Without Development (WOD) models.
• Monitor environmental water management by evaluating triggers for noncompliance action.

Strengths

• Data is modelled annually using the best available models, as stated in the description.
• Flows are simulated for several gauges in each river system, providing multiple points of analysis.
• Model is configured to represent specific Water Sharing Plan rules, linking data directly to regulatory frameworks.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
