Hydroclimatic Atlas 2022: River Flow Indicators for Southern Quebec

Southern Quebec's 2022 Hydroclimatic Atlas models current and future water regimes to support climate-resilient water management. The dataset includes 24,604 river sections with attributes and 76 hydrological indicators for historical and future climate scenarios. It is published by the Government and Municipalities of Québec under a CC-BY-4.0 license.

Use Cases

• Projecting future river flow magnitudes and directions based on 76 hydrological indicators for RCP4.5 and RCP8.5 scenarios.
• Analyzing spatial patterns of hydrological change across 24,604 river sections in southern Quebec.
• Assessing uncertainty in flow projections using the multiple hydrological platforms and climate model ensembles mentioned in the description.
• Supporting the implementation of resilient water management practices based on modeled future water regimes.

Strengths

• Includes 76 distinct hydrological indicators describing amplitude, direction, and dispersion of flow.
• Covers 24,604 river sections across southern Quebec, with improved spatial resolution and coverage.
• Uses multiple climate scenarios (CMIP5, ClimeX, CORDEX-NA) and six hydrological platforms for projection robustness.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the CSV tables is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to its focus on southern Quebec.
