Goal: Method for Integrated Hazard Planning
Assess value Value of coastal habitats to
business, community, ecosystems
Evaluate Options Habitat protection, restoration,
gray infrastructure
Develop Strategy Integrate green infrastructure
portfolio into planning

Landcover and Green Infrastructure Scenarios
High Green
• Dry Land below 2100 SLR salt line gets restored or allowed to convert to wet/marsh
• Developed below SLR remains*

Landcover and Green Infrastructure Scenarios
Moderate Green
• Limited Development – 2040 projections • Protect or restore wet habitats with
highest expected net benefits

Sea Level Affecting Marshes Model (SLAMM)
![Page 10: Green and Gray Infrastructure - conference.ifas.ufl.edu Tuesday/2 Key... · Acknowledgments •TNC-Sustainability Science: Sheila Walsh, Jon Fisher, Anthony Rogers, Alex Maas, Jen](https://reader034.vdocuments.us/reader034/viewer/2022042300/5ecb7db905853f2c713fe74e/html5/thumbnails/10.jpg)
Sea Level Affecting Marshes Model (SLAMM)
Within SLAMM, there are six primary processes:
1. Inundation: T he rise of water levels and the salt boundary
2. Erosion: Triggered based on a threshold of maximum fetch and the proximity
of the wetland to estuarine water or open ocean.
3. Overwash: Barrier islands of under 500 meter width are assumed to undergo
overwash during each 25 year time-step due to storms encountered.
4. Saturation: Coastal swamps and fresh marshes can migrate onto adjacent
uplands as a response of the water table to rising sea level close to the coast.
5. Accretion: Upward movement of marshes due to sequestration of sediments
and biogenic production.
6. Salinity: Optional. In a location with defined fresh-water flows, land categories
can migrate based on changes in salinity.
