National Assessment of Storm-Induced Coastal Change Hazards

Hurricane Joaquin Storm Response

Pre- and Post-Storm Photo Comparisons - North Carolina

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 triplicates 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. Near vertical pre-storm aerial photos were acquired by National Oceanic and Atmospheric Administration (NOAA) during a baseline survey on June 13, 2015 and post-storm photos were acquired October 7, 2015.  Low angle post-storm oblique photos were also acquired by the U.S. Geological Survey (USGS) on October 9, 2015.

pre- and post-storm photos
Location 1: Near vertical (top, middle) and low angle oblique (bottom) aerial photographs of Topsail, NC. View looking northwest along the North Carolina shore. Elevated storm-induced water levels overtopped the low dunes here causing the dune to overwash. Sand was transported landward, burying the marsh (green arrow). The yellow arrows in each image point to the same feature. Near vertical images courtesy of National Oceanic and Atmospheric Administration. [larger version]

Location 2: Near vertical (top, middle) and low angle oblique (bottom) aerial photographs of Camp Lejeune, NC. View looking northwest along the North Carolina shore. Waves and surge from Hurricane Joaquin eroded the beach, causing significant shoreline retreat and a narrower beach. An overwash channel was reactivated, moving sand inland (green arrow) burying the marsh. The yellow arrows in each image point to the same feature.

Location 3: Near vertical (top, middle) and low angle oblique (bottom) aerial photographs of Bear Inlet, NC. View looking northwest along the North Carolina shore. High waves and storm surge from Hurricane Joaquin eroded the beaches, moving sand inland (green arrow) and reshaping the flood-tidal shoals. The yellow arrows in each image point to the same feature. Near vertical images courtesy of National Oceanic and Atmospheric Administration. [larger version]

Location 4: Near vertical (top, middle) and low angle oblique (bottom) aerial photographs of New Drum Inlet, Core Banks, NC. iew looking northwest along the North Carolina shore. High waves and storm surge from Hurricane Joaquin reopened New Drum Inlet, transporting sand into Core Sound (green arrow) and reworking the shoals of the flood-tidal delta behind the inlet. The yellow arrows in each image point to the same feature. Near vertical images courtesy of National Oceanic and Atmospheric Administration. [larger version]

pre- and post-storm photos
Location 5: Near vertical (top, middle) and low angle oblique (bottom) aerial photographs of Hatteras, NC. View looking north along the North Carolina shore. Waves and surge from Hurricane Joaquin eroded the beach, causing significant shoreline retreat and a narrower beach at the location of the Hurricane Isabel breach in 2003 (green arrow). The yellow arrows in each image point to the same feature. Near vertical images courtesy of National Oceanic and Atmospheric Administration. [larger version]

Location 6: Near vertical (top, middle) and low angle oblique (bottom) aerial photographs of Salvo, NC. View looking west along the North Carolina shore. Waves and surge from Hurricane Joaquin eroded the beach, causing significant shoreline retreat and a narrower beach, leaving deposits of darker sand at the base of the dune (green arrow). The yellow arrows in each image point to the same feature. Near vertical images courtesy of National Oceanic and Atmospheric Administration. [larger version]

Location 7: Near vertical (top, middle) and low angle oblique (bottom) aerial photographs of Rodanthe, NC. View looking west along the North Carolina shore. High waves and storm surge from Hurricane Joaquin eroded the beach, exposing the pilings of the homes to wave attack (green and orange arrows). The yellow box delineates the view of the low angel oblique photo. Orange arrows in each image also point to the same structure.

pre- and post-storm photos
Location 8: Near vertical (top, middle) and low angle oblique (bottom) aerial photographs of Oregon Inlet, NC. View looking west along the North Carolina shore. High waves and storm surge from Hurricane Joaquin eroded the beach and inundated the low area in the backshore at Oregon Inlet (A, green box, blue arrows). Waves and surge also eroded the base of the dune further north (B, yellow arrows, yellow box) along the shore. The orange and green arrows (in A and B, respectively) in each image point to the same feature. Near vertical images courtesy of National Oceanic and Atmospheric Administration. [larger version]
