Title
Maryland Wetland Adaptation to Sea Level Rise - Sea Level Affecting Marshes Model SLAMM by 2100 [Maryland]
Description
SLAMM uses elevation, accumulation of sediments, wetland accretion and erosion rates, and sea level rise to predicatively model long-term wetland and shoreline changes. In Maryland, SLAMM was run using the best available science, including sea level rise rates identified at 4.03 feet by year 2100, using base sea levels in the year 2010. The resulting changes to coastal marshes and shorelines can be visualized in their future states by 2050, 2070, and 2100 under a scenario of growing global greenhouse gas emissions with a probability of at least 17%. These results will be used to help frame new land conservation targeting in Maryland's coastal zone.
