Living shorelines are a nature-based solution to help stabilize coastal ecosystems from erosion due to waves, sea-level rise (SLR), and storm surge. There are other benefits to using “soft” shorelines, in addition to combating erosion, such as restoration of critical ecosystem services and creating wildlife habitat. Living shorelines are used across coastal and estuarine areas of the US coming in a variety of designs. Our research focuses on evaluating the ability of these different designs to mitigate waves to facilitate more-informed decisions regarding coastal erosion. Our study area is a coastal wetland near the Point-Au-Chien Indian Tribe, which is particularly susceptible to SLR and storm surge due to its low-lying location and the surrounding intensive anthropogenic influences related to oil and gas exploration, such as dredged canals.  The CSHORE-VEG model, developed by the Army Corps ERDC, is a numerical model that allows us to incorporate hydrodynamic factors, biomechanical features, and vegetation properties, such as structure and density, to determine wave height and other physical variables. This model allows us to predict wave height with and without living shorelines under a variety of SLR scenarios. In order to facilitate the choice of locations, we will apply a wetland change model developed in our lab to identify vulnerability hotspots. The model will calculate accretion and erosion and account for saltwater intrusion due to dredged canals which is important since enhanced salinity and water level both could increase the rate of salt marsh submergence. The results will determine the living shoreline's ability to mitigate wave energy and combat erosion within the salt marsh ecosystems surrounding the tribal communities.  Our research will provide refined data that allows the Point-Au-Chien to better identify temporal and spatial impacts of sea level rise and develop mitigation strategies that protect both human infrastructure and critical ecosystems.
