Sea Level Affecting Marshes Model (SLAMM)

This open-source downloadable model uses digital elevation data and other information to simulate potential impacts of long-term sea level rise on wetlands and shorelines. The model simulates the dominant processes involved in wetland conversions and shoreline modifications during long-term sea level rise. Map distributions of wetlands are predicted under conditions of accelerated sea level rise, and results are summarized in tabular and graphical form. 

SLAMM has been used in several geographies and applications across the nation since its development in the mid-1980s.
