Short summary
Studies of the impact of storms on dunes typically focus on the importance of dune elevation, here we analyze the protective services offered by the dune height and width, the morphology of the beach fronting the dune, and artificial dune construction via the use of sand fences. We find that dune volume loss most strongly correlates to beach width rather than dune shape, although when beach width is controlled for low and wide dunes offer greater protection than tall and narrow dunes.
