Hurricane Matthew Storm Response

Pre- and Post-Storm Photo Comparisons - Georiga

Hurricane Matthew tracked offshore of the Georgia coastline as a Category 2 storm, causing extensive erosion of the beach and sand dunes. 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, August 24, 2011, and post-storm photos were acquired on October 14, 2016.

pre- and post-storm photos
Location 1: Oblique aerial photographs at Cumberland Island, Georgia. Oblique aerial photographs collected before (top) and after (bottom) Hurricane Matthew. Storm waves eroded the dune face causing a steep scarp (red arrow). The yellow and red arrows in each image point to the same features in both photos. [larger version]

pre- and post-storm photos
Location 2: Oblique aerial photographs at Sea Island, Georgia. Oblique aerial photographs collected before (top) and after (bottom) Hurricane Matthew. Storm waves and surge eroded the seaward-most dune, exposing the marsh platform, and allowing sand to overwash into the marsh. The yellow and red arrows in each image point to the same locations in both photos. [larger version]

pre- and post-storm photos
Location 3: Oblique aerial photographs at Little St. Simons Island, Georgia. Oblique aerial photographs collected before (top) and after (bottom) Hurricane Matthew. A combination of long-term erosion and storm-induced waves and water levels has resulted in shoreline retreat. The red arrow points to the same line of vegetation in both photos, denoting the loss of the seaward-most dunes. The yellow arrows points to a boat wreckage that was demolished and buried.

pre- and post-storm photos
Location 4: Oblique aerial photographs at St. Catherines Island, Georgia. Oblique aerial photographs collected before (top) and after (bottom) Hurricane Matthew. Storm waves and currents eroded the sand dunes, allowing sand to be transported landward into the marsh. The yellow arrows in each image points to the same features in both photos. [larger version]

pre- and post-storm photos
Location 5: Oblique aerial photographs at Ossabaw Island, Georgia. Oblique aerial photographs collected before (top) and after (bottom) Hurricane Matthew. Storm waves and currents overtopped the dunes allowing sand to overwash into the marsh. The mud from the exposed marsh platform can also be seen along the shoreline. The yellow arrows in each image points to the same features in both photos. [larger version]
