Overview

As the foremost experts in programming and applying the Sea-Level Affecting Marshes Model (SLAMM), the Warren Pinnacle Consulting (WPC) team has produced projections for thousands of miles of the US Atlantic and Gulf of Mexico Coasts. They provide the information needed to design plans for marsh migration corridor preservation, marsh restoration, infrastructure protection, and habitat conservation.

Their expertise in modeling bioaccumulation in aquatic systems spans multiple models and ecosystem types. The WPC team includes the primary programmer for the EPA AQUATOX water ecology and toxicant fate model. In addition, they have extensive experience programming and applying the AQEA foodchain and FishRand-Migration models.

SLAMM 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.

The newest versions of SLAMM include a Roads module to investigate the inundation frequency of road infrastructure and a stochastic uncertainty analysis module for assessing the effects of input data uncertainty on model predictions. The uncertainty analysis module can be used to produce confidence intervals for model predictions and likelihood maps.

SLAMM Documentation also available in Spanish: Overview and Users Manual.
