Introduction to Alaska's Shorelines and Understanding Shoreline Change

Coastal vulnerability is often described by the rate of shoreline change along a section of coast. These rates range from long-term change (e.g., 1 foot per year of retreat) to erosion from a single storm event (e.g. 100 linear feet of erosion). Rates of shoreline change, however, are highly dependent on the type of shoreline being measured, the calculations being used to determine the rate of change, and the data available to define shoreline positions. The Alaska Division of Geological & Geophysical Surveys' Coastal Hazards Program has created an online tooll with a written guide to provide background on how shoreline positions are defined and how rates of shoreline change are determined. This talk will introduce the shoreline and shoreline change to the general user with examples from the Alaska Shoreline Change Tool that show some of the uses and limitations of shoreline change rates and projections of shoreline positions.
