Modelled Daily River Flow Rates for Castlereagh Valley, NSW

New South Wales river systems provide modelled daily flow rates in megalitres per day for the Castlereagh Valley. Data is generated using the best available hydrologic models at the time of publishing and covers a historic climate period typically from the early 1890s to the water year prior to publication. The NSW Department of Climate Change, Energy, the Environment and Water updates specific scenario data sets annually, subject to quality requirements for use in relevant studies.

Use Cases

• Calibrate hydrological models based on long-term modelled flow time series.
• Assess water availability for the Castlereagh Valley based on modelled daily flow rates.
• Study the impact of climate variability on river systems using historic climate period data.
• Support water resource planning and policy development using annually updated scenario data sets.

Strengths

• Time series covers a long historic period, typically from the early 1890s.
• Data sets are updated annually and subject to quality requirements.
• Models use the best available hydrologic models at the time of publishing.

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 and temporal bias inherent to the source models.
