Short summary

This work presents a methodology to conduct a probabilistic analysis of the storm impact on a barrier island. A subset of wave conditions from a 30-year hindcast is propagated to the shore to predict the extreme run-up. Subsequently, a 30-year run-up hindcast is estimated using a multivariate interpolation technique. This information is used to derive a new run-up parameterization that predicts both the run-up saturation and its dependency on sea level as observed in the downscaling results.
