Glacial Lake Outburst Flood Simulations for the Poiqu Basin

Simulation results for large ice/rock avalanche triggered glacial lake outburst floods in the Poiqu Basin, conducted with r.avaflow. The data are presented in the paper by Allen et al. 2022, published in Natural Hazards and Earth System Science. Raster files of flow height are provided for simulations of Galongco, Jialongco, and a Future Lake, alongside an Excel file with time series data.

Use Cases

• Modeling flood inundation extents based on raster flow height data.
• Analyzing flood discharge dynamics over time based on the provided time series.
• Assessing glacial lake outburst flood hazards under current and future conditions.
• Calibrating hydrological models using the simulated cross-section data at Nyalam and Zhangmu.

Strengths

• Simulations are based on specific, named glacial lakes (Galongco, Jialongco) and a Future Lake scenario.
• Data includes both spatial raster outputs and temporal cross-section measurements.
• Results are linked to a peer-reviewed publication (Allen et al. 2022) providing methodological context.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
