Mapping Major Floods in Quebec, Canada from April-May 2017

Quebec, Canada, experienced major spring floods in April-May 2017 affecting regions including Montérégie, Laurentides, Mauricie, Montréal, and Laval. The dataset contains geomatic data, such as satellite images, captured to document these floods, which exceeded a 100-year recurrence interval. It is provided by the Government and Municipalities of Québec under a CC-BY-4.0 license.

Use Cases

• Modeling flood extent and severity based on satellite imagery captured during the event.
• Analyzing hydrological peak conditions based on described flow rates (e.g., 3400 m3/s on Rivière des Prairies).
• Assessing infrastructure and land-use vulnerability in flood-prone regions of Quebec.
• Calibrating flood recurrence models using the documented 100-year exceedance event.

Strengths

• Documents a specific, high-impact flood event exceeding a 100-year recurrence interval.
• Includes precise hydrological measurements from official sources, such as a peak flow of 8900 m3/s on the Ottawa River.
• Offers data in multiple geospatial formats (WMS, SHP, GEOJSON) for flexibility in analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Description metadata was translated via an automated tool, which may introduce ambiguities.
