GIS compatible spatial layers covering the coast of Kauai (other than Na Pali) showing the 80%ile erosion hazard zone under 1 ft of SLR (ca. mid-century) and 3 ft of SLR (ca. end of century). Step 1: Use historical shoreline analysis to determine shoreline positions in the absence of increased SLR for 2005-2100. Step 2: Determine the additional SLR in excess of historical SLR trends using local tide gauge data and modeled future sea levels. Step 3: Translate additional climate induced SLR, in Step 2, to shoreline recession. Step 4: Integrate historic shoreline models with geometric models to create spatial layers for maps and graphs.
