Elevation difference maps of Deal, New Jersey

elevation difference maps of Deal, New Jersey

Detailed Description

Pre-storm elevation map, post-storm elevation map, and elevation difference map of Deal, New Jersey. At center-left, a rock wall had been built behind the beach and in front of an open field. At center-right, a line of dunes had been built behind the beach and in front of two clusters of buildings. The rock wall survived the storm surge and wave runup but the land behind it was eroded, creating a large scarp. The line of constructed dunes was washed away. 

In the pre- and post-storm elevation maps, orange and red colors indicate higher elevations while yellow and green colors indicate lower elevations. In the elevation difference maps, red colors indicate erosion such as shoreline retreat, and blue-green colors indicate accretion, such as overwash deposits where waves and surge have moved sand landward. Maps are oriented with the Atlantic Ocean on the bottom.
