Global sea level increases will impact the Southern California coastlines over the next one hundred years. The California Coastal Commission is concerned with potential threats to coastal wetlands, habitats, and marine species. The Carlsbad Fish and Wildlife Office (CFWO) of the U.S. Fish and Wildlife Service needed a GIS solution to be used with the Sea Level Affected Marshes Modeling (SLAMM) application to predict the potential effects of sea level rise. SLAMM is a simulation process that predicts wetland conversions and shoreline modification during long-term sea level rise. Three tools were developed using ArcGIS software to enable users to conduct risk analyses of coastlines by identifying vulnerable wetland areas, and to produce outputs that can be used for analysis. This tool will enable the CFWO to conduct accurate analyses to aid decision makers to put forward policies that preserve existing coastlines, habitats and species. (10538 kB)
