Namoi River System Long-Term Average Annual Extraction Limits and Modeled Flows

Long-term average annual extraction limits (LTAAEL) are regulatory caps designed to ensure sustainable water use in New South Wales river systems. The NSW Department of Climate Change, Energy, the Environment and Water provides this dataset containing flows at several gauges, simulated by an annually extended LTAAEL model configured to represent water sharing plan rules. These modeled flows can be compared with outputs from other key scenario models like the annual permitted take (APT) or without development (WOD) models.

Use Cases

• Assess regulatory compliance by comparing modeled long-term average annual extractions (LTAAEs) against extraction limits (LTAAELs).
• Analyze the impact of water sharing plan rules on river system flows based on the LTAAEL model simulations.
• Compare water extraction scenarios by contrasting LTAAEL model outputs with results from the annual permitted take (APT) or without development (WOD) models.
• Monitor long-term water sustainability trends in the Namoi river system using the annually updated model data.

Strengths

• Data is produced annually using the best available models, ensuring regular updates.
• Model is configured to represent specific water sharing plan (WSP) development and management rules.
• Flows are simulated at several gauges within each river system, providing multiple points of analysis.

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.
• The model has inherent limitations, as acknowledged in the description.
