Overview: From 2008 to 2013 the Sea Level Affecting Marshes Model (SLAMM) was applied to more than ten million hectares of the Gulf of Mexico coastline. However, simulation results were not directly comparable due to differences in model domain definitions, accretion modeling approaches, and future sea-level scenarios. In addition, several gap areas had not yet been modeled. In 2014, the GCP LCC funded this analysis of the US Gulf of Mexico Coast in order to establish a consistent framework of data and models. The main objectives of this project were to generate a seamless set of landcover projections for the Gulf of Mexico coast using SLAMM and conduct a focal species analysis using SLAMM results. Additional project goals included deriving and applying mechanistic accretion feedbacks for coastal marshes, analysis of the effects of low-quality (non-LiDAR) elevation data on model results, and posting the SLAMM outputs to SLAMM-View for public access to results.
