Q-CLASS: Reconstructed Streamflow at China's Large Dam Sites, 1961-2014

Q-CLASS provides reconstructed natural and actual streamflow data for China's large dam sites from 1961 to 2014, with measurements in units of 10,000 cubic meters per year. The dataset, published by Yu et al. in 2026, is stored in a 557.3 KB ZIP file containing two CSV files. It is shared under a CC-BY-4.0 license on figshare.

Use Cases

• Modeling long-term hydrological changes based on reconstructed natural streamflow.
• Analyzing the impact of dams on river systems based on the comparison between natural and actual streamflow.
• Calibrating water resource management models using the 54-year temporal coverage.
• Studying regional water availability trends in China based on the dam site data.

Strengths

• Provides a 54-year continuous time series from 1961 to 2014.
• Includes both natural and actual streamflow reconstructions for comparative analysis.
• Published in a peer-reviewed journal (Journal of Hydrology) with a DOI.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (557.3 KB), indicating limited scope or aggregation level.
