Dune topography did not reflect the coastal contexts of wave and tidal energy in a causal relationship. There were propensities for island morphology to contribute to similarity in dunes. However, there was also evidence that the processes acting in one location on an island should not be extrapolated to neighboring islands or even to locations on the same island. Wave-dominated barrier islands may exhibit more convergence of dune topographic form. More tidally-dominated mixed energy barrier islands have greater divergence of topography.
