The MELCCFP has tasked Geosapiens with producing and documenting an approximate flood‑extent layer for extreme events across Québec.

Coastal flooding occurs when mean sea level, tides, and variable surge and waves align. This study separates deterministic factors (tides, long-term sea level) from stochastic ones (surge, wave setup) and models extremes of the random part, rather than treating total water level as a single metric. This approach improves physical and statistical robustness for global flood risk and catastrophe models.

Geosapiens empowers financial institutions and insurers to meet OSFI B-15 and international disclosure standards.
