Marshes on the Move
A Manager’s Guide to Understanding and Using Model Results Depicting Potential Impacts of Sea Level Rise on Coastal Wetlands
Link to document: Marshes on the Move
This document is intended for people who need to use model outputs for decision-making, but who do not build models themselves.
Information in this document applies to a wide range of coastal wetlands, including
- tidal freshwater, brackish, and salt marshes, and
- coastal freshwater forested and riparian wetlands
The following are examples of management questions that models can help to address about impacts of sea level rise on coastal wetlands:
- Which wetlands in the management area are most vulnerable under different sea level rise scenarios?
- What areas of a present-day wetland may become open water, and what areas of upland may become wetland?
- Where could wetlands migrate inland without encountering natural or anthropogenic barriers?
- How would a wetland’s vulnerability to sea level rise be affected by changes in factors such as river discharge, sediment inputs,and adjacent land use? Where could restoration reduce a wetland’s vulnerability?
- How much economic damage from increased flooding is likely to occur because of loss of wetlands in a given geographic area?
- Which populated areas are most vulnerable?
- How much would it cost to implement various adaptation strategies?
- Are wetlands in the management area likely to continue protecting coastal properties from storm damage as sea level rises? What management actions could be taken to sustain and enhance the role of wetlands in coastal hazard mitigation?
