National Assessment of Storm-Induced Coastal Change Hazards

Hurricane Joaquin Storm Response

Pre- and Post-Storm Photo Comparisons - New Jersey

Hurricane Joaquin, though it did not make direct landfall on the U.S. coastline, affected a broad swath of mid-Atlantic and North-eastern states, from South Carolina to Massachusetts. Onshore winds from Joaquin combined with a non-tropical low pressure system led to high waves and elevated total water levels that impacted the coast for several days, causing extensive beach and dune erosion and even overwash in some locations. Here, photos pairs are used to compare the pre-storm and post-storm conditions at locations representing a broad range of coastal configurations and their response to the storm. Pre-storm photos were acquired during a baseline survey on October 6, 2014 and post-storm photos were acquired October 7, 2015.

pre- and post-storm photos
Location 1: Oblique aerial photographs of Stone Harbor, NJ. View looking west along the New Jersey shore. Storm waves and surge have eroded the reconstructed dune seen in the upper image (area fenced off and planted with grass) and left a steep dune scarp (green arrow). The yellow arrow in each image points to the same feature. [larger version]

pre- and post-storm photos
Location 2: Oblique aerial photographs of Tucker Island, NJ. View looking west along the New Jersey shore. This section of coastline has likely overwashed many times in the past and again during Hurricane Joaquin. New sand has filled in low elevations in the existing overwash deposit (green arrow). The yellow arrow in each image points to the same feature. [larger version]

pre- and post-storm photos
Location 3: Oblique aerial photographs of Long Beach, NJ. View looking west along the New Jersey shore. The beach has become wider due to ongoing beach nourishment activities. The yellow arrow in each image points to the same feature. [larger version]

pre- and post-storm photos
Location 4: Oblique aerial photographs of Mantoloking, NJ. View looking west along the New Jersey shore. A seawall constructed after Hurricane Sandy (upper image) has been exposed by waves reaching the base of the wall, possibly during Hurricane Joaquin. The beach above the seawall is steeply scarped indicating further erosion. The yellow arrow in each image points to the same feature. [larger version]

pre- and post-storm photos
Location 5: Oblique aerial photographs of Mantoloking, NJ. View looking west along the New Jersey shore. A seawall constructed after Hurricane Sandy (upper image) has been exposed by waves reaching the base of the wall, possibly during Hurricane Joaquin. The beach above the seawall is steeply scarped and sand has slumped over the wall (green arrow). The yellow arrow in each image points to the same feature. [larger version]

pre- and post-storm photos
Location 6: Oblique aerial photographs of Bay Head, NJ. View looking west along the New Jersey shore. The rip rap seawall has been exposed by waves and high water levels (green arrow). The yellow arrow in each image points to the same feature. [larger version]

pre- and post-storm photos
Location 7: Oblique aerial photographs of Long Branch, NJ. View looking west along the New Jersey shore. A beach scarp is visible in both pre and post-storm images (green arrow), though the post-Joaquin beach scarp is further up the beach indicating higher water levels. The rip rap groin also became exposed since 2014 (orange arrow) indicating beach erosion. The yellow arrow in each image points to the same feature. [larger version]
