Coastal environments along the Cape Fear Arch of North and South Carolina were heavily impacted by the autumn 2018 hurricane season. Florence in particular was damaging, making landfall in North Carolina as a Category 1 storm. Understanding how shorelines respond to high-energy events on multiple timescales is key for preparation and mitigation of effects from future storm events. This paper compares the outputs of two shoreline change models, Analyzing Moving Boundaries Using R (AMBUR) and the Digital Shoreline Analysis System (DSAS), to project shoreline response from Hurricanes Florence and Michael from Cape Fear, NC to Cape Romain, SC. Shorelines will be digitized from post-storm aerial imagery and compared to known pre-storm baselines. These projections will be used to analyze impacts and spatial patterns of shoreline change at regional and local scales. The results from this study will be used to develop guidelines to model selection and operation in research and management contexts.
