Sea Level Affecting Marshes Model
Environmental Protection Agency and Warren Pinnacle Consulting
Features
- Addresses various wetland scenarios, including inundation, erosion, overwash, saturation, and salinity
- Computes relative sea level change for time sequences of 5 to 25 years
- Incorporates areas protected by dikes and other hard structures if needed
- Incorporates sedimentation and accretion rates and provides options for computing erosion
- Incorporates standard coastal wetland classes
- Provides outputs that can be viewed in a geographic information system (GIS) or other software for additional analysis
Overview
This mathematical model uses digital elevation data and other information to simulate potential impacts of long-term sea level rise on wetlands and shorelines. SLAMM has been used in several geographies and applications across the nation since its development in the mid-1980s.
