Just how big do coastal marshes need to be to do their job as protectors of the coastline? N-EWN researchers from the University of Georgia, Viyaktha Hithaishi Hewageegana, Matt Bilskie, Brock Woodson, and Brian Bledsoe investigated the matter by running simulations that tested how changes in marsh geometry impacted the storm surge and amount of flooding.

Just as engineers use data and modeling when ensuring that the structures they build will hold, this kind of modeling helps to build a foundation of knowledge for future coastal managers and engineers to utilize as they incorporate natural infrastructure, like marshes, into their coastal resilience plans.
