Projections of compound floodwater depths for the lower Nooksack River and delta, western Washington State
Computed flood depths associated with the combined influence of sea level position, tides, storm surge, and streamflow under existing conditions and projected future higher sea level and peak stream runoff are provided for the lower (Reach 1) of the Nooksack River and delta in Whatcom County, western Washington State. The flood-depth projection data are provided in a series of raster geotiff files. Flood-depth projections were computed using a system of numerical models that accounted for projected changes in climate forcing including sea level rise, storm surge, and stream discharge in the 2040s and 2080s based on the Coupled Model Intercomparison Project Phase 5 (CMIP5) Global Climate Model (GCM) projections. Additionally, the models were run with modifications to land surface elevations to represent proposed flood hazard reduction and salmon habitat restoration strategies (alternatives) under existing and future conditions. Variations of the models also simulated changes to the stream bed to reflect recently observed decadal-scale sedimentation patterns that affect flow conveyance and flood risk.
