Historic Flood Susceptibility Maps for Canada from 2000 to 2023

Natural Resources Canada provides a series of historic flood susceptibility maps for Canada. The maps are generated by an XGBoost machine learning model trained on major floods from 2005 to 2023 and run for each year from 2000 to 2023. The model incorporates temporal characteristics of temperature, precipitation, land use, land cover, and NDVI to predict annual flood susceptibility.

Use Cases

• Analyzing temporal trends in flood susceptibility based on the modeled annual outputs from 2000 to 2023.
• Comparing flood risk projections with historic susceptibility values mentioned in the broader collection.
• Integrating modeled flood susceptibility with other geospatial layers like land use and NDVI for environmental planning.

Strengths

• Model is trained on major flood events from a specific 18-year period (2005 to 2023).
• Provides annual predictions for a 24-year period (2000 to 2023).
• Incorporates multiple dynamic environmental variables: temperature, precipitation, land use, land cover, and NDVI.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal/source bias inherent to open_canada.
