Abstract
Improved identification of morphological responses to storms is necessary for developing and maintaining predictive models of coastal change. Morphological responses to Hurricane Sandy were measured using lidar and orthophotos taken before and after the storm. Changes to dune features measured from lidar were compared to the occurrence of overwash deposits measured using orthophotos. Thresholds on morphologic change (e.g. overwash volume and dune height change) were defined to optimize agreement between the classification of lidar and orthophoto-derived dune erosion and overwash. A linear regression showed that overwash volume can be calculated from orthophoto-derived overwash extent.
