Tsälnjik Chú (Nordenskiold River) near Carmacks in Yukon is characterized by geomorphic observations, photogrammetry, and hydrological analysis. The dataset includes channel-migration data related to flooding patterns, including a ~10-year recurrence flood event from spring 2022. Borehole data indicates discontinuous permafrost at depths >0.7 m, and results provide a hazard characterization for bank erosion and channel overspill.
Use Cases
- Modeling channel migration rates based on geomorphic observations and photogrammetry.
- Analyzing flood hazard risks based on the characterization of bank erosion and channel overspill.
- Studying relationships between river curvature, size, and migration rate in permafrost zones.
- Assessing watershed responses to environmental stressors like permafrost thaw based on hydrological analysis.
Strengths
- Includes data from a recent ~10-year recurrence flood event (spring 2022).
- Borehole data provides permafrost depth information (>0.7 m).
- Integrates multiple analysis methods: geomorphic observations, time-series photogrammetry, and hydrological analysis.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
