Flood extent and uncertainty projections at Golovin, Alaska

Flood extents, as well as the upper and lower uncertainty bounds of flood extents, from compound coastal hazards—specifically sea-level rise (SLR) and projected coastal storms—are provided for Golovin, Alaska. These products are consistent with other data in this release (for example, flood depths and event-driven erosion; Erikson and others, 2025), supporting integrated coastal hazard assessments for Alaskan communities. The data are provided as shapefiles 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).
