Evaluating the Impact of Hydrologic Alterations on Salt Marsh Sustainability in a Changing Climate

Project Overview Resource
October 2018

Parallel grid ditches were dug in approximately 90% of mid-Atlantic and New England salt marshes in the 1920s through the 1940s. Today, managers must navigate the effects of past actions when making decisions about marsh hydrology and drainage that impact human health, ecosystem services, and marsh sustainability. Managers must also consider how stressors such as sea-level rise impact marshes. A collaborative research project helped to address this challenge by working iteratively with end user groups to develop a decision support tool for marsh hydrology management strategies that promote sustainability and delivery of valuable ecosystem services under future sea-level scenarios.

About this resource

This project overview describes a 2017-2020 Collaborative Research project that involved scientists and end users in Cape Cod, Massachusetts working together to develop decision-support tools for marsh hydrological management strategies that promote sustainability and delivery of valuable ecosystem services under future sea level scenarios. The overview outlines the project approach, key findings, products and outcomes.
