Sea level rise will significantly increase the need for building and upgrading coastal protection such as dunes living shorelines. (Morris et al., 2020). Even if emission goals are reached, most coastlines experience an in mean sea levels energetic wave events storms Coastal measures, dune restorations engineered dunes, crucial adaptation efforts worldwide (Temmerman 2013; Morris 2022) hold many advantages over traditional hard engineering structures walls. However, at sites with more urgent needs limited space, hybrid offer benefits of both soft (e.g., dunes) structures, example consisting a sand containing solid structure or rock core (Almarshed In this study, data from five years shoreline observations presented, including performance during historic 20-year event on intermediate, long-period swell beach. Morphological models tested hybrid-dune erosion overwash compared to high resolution morphological field observations.
