Alaska Shoreline Change Maps

Many of Alaska's coastal communities are vulnerable to erosion, flooding, and permafrost degradation. However, few vulnerability assessment tools are available to the public that are complete or that utilize transparent, consistent, and quantitative methods at a scale needed for local planning. This report summarizes statewide analyses of long-term shoreline change at 48 Alaska communities.
