Erosion and sedimentation projections at Golovin, Alaska

Erosion and sedimentation maps resulting 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 extent and velocity hazards; Erikson and others, 2025), supporting integrated coastal hazard assessments for Alaskan communities. The data are provided as gridded maps (GeoTIFFs) for 30 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).
