Over the past two decades the southeast coast of the U.S., and especially the east coast of Florida, has been subject to rising coastal ocean sea levels at rates three times higher than the 100-year trend due to the slowing of the Gulf Stream. This, combined with frequent tropical cyclones, limited local sources of terrigenous sands, and rapid development of human infrastructure, has transformed a once stable barrier island setting into an environment of erosion and coastal transgression (Zarillo, 2023). In this situation, erosion hotspots may appear, evolve through a life cycle, and then disappear and reestablish at other locations. Thus, this work aims to evaluate the potential of portable and temporary breakwaters as a treatment for chronic shore erosion and erosion hotspots transgression. This study evaluates the potential of Coastal Recovery Shoal Modules (CRSMs) as a mobile temporary or permanent solution to mitigate erosion. Two configurations of CRSM-based breakwaters were modeled using hydrodynamic and sediment transport simulations calibrated to field data. Results demonstrate that module arrangements can reduce sand volume loss and wave energy, particularly when crest elevations are optimized. This approach shows promise as a sustainable shore protection.
