Projections of coastal flood depths for Whatcom County, Northwest Washington State coast (2015-2100)

Metadata Updated: July 6, 2024

Projected flood depths associated with compound coastal flood hazards for future sea-level rise (SLR) and storm scenarios are provided for Whatcom County, Washington, in a series of raster geotiff files. Projections were made using a system of numerical models with atmospheric forcing, tides, sea level position and stream discharge driven by output from Global Climate Models (GCMs) from the Coupled Model Intercomparison Project Phase 5 (CMIP5). The resulting computed coastal flood depths along the Whatcom County coast due to predicted sea level rise and future storm conditions consider the changing climate. In addition to sea-level rise, flood simulations run by these numerical models included dynamic contributions from tide, storm surge, wind, waves, and seasonal sea-level fluctuations. In the absence of concordant downscaled GCM stream discharge, daily average stream discharge was fed to the model. Outputs include flood depths from the combinations of SLR scenarios (0, 0.25, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 and 5.0 m) storm conditions including 1-year, 5-year, 10-year, 20-year, 50-year and 100-year return interval storms and a background condition (no storm - astronomic tide and average atmospheric conditions). Predicted flood depths during the largest annual astronomic tides (King Tide) in combination with an average storm surge scenario are also provided.
