Flood depth projections at Utqiagvik, Alaska

Flood depths from compound coastal hazards—specifically sea-level rise (SLR) and projected coastal storms—are provided for Utqiagvik, Alaska. The flood depth products are consistent with other data in this release (for example, flood extent and event-driven erosion; Erikson and others, 2025), supporting integrated coastal hazard assessments for Alaskan communities. The data are provided as gridded maps (GeoTIFFs) for 36 storm and SLR combinations (SLR scenarios 0, 0.5, 1.0, 1.5, 2.0, and 3.0 meters combined with 1-year, 10-year, 20-year, 50-year, and 100-year storm return periods, as well as the background, no storm, conditions). These data are also provided for areas landward of the present-day shoreline only to make the impact of each scenario more visible. These are available for all mentioned storm and SLR combinations but the background condition with no SLR (since this scenario does not exceed the present-day shoreline).
