Assessing the Effectiveness of Nourishment in Decadal Barrier Island Morphological Resilience: Model Inputs and Outputs

The effectiveness of nourishment in decadal barrier island morphological resilience was assessed using the XBeach model to simulate morphologic change over a 30-year period at Dauphin Island, AL, under scenarios of no-action and beach and dune nourishment, as described in Passeri et al., 2021. The 30-year simulation used a storm climatology developed for the region based on synthetic tropical cyclones and a moderate projection of future sea level rise. The initial (year 0) and final (year 30) model elevations (topography and bathymetry) are provided here, as well as the post-storm elevations from each event that was simulated (storm numbers correspond to the synthetic storm number). For further information regarding model input generation and visualization of model output topography and bathymetry, refer to Passeri et al., 2021.
