Drone Imagery Shows Substantial Erosion on Miami Beach from Hurricane Matthew

Ongoing U.S. Army Corps of Engineers Miami Beach Erosion Control and Hurricane Protection project appears to be hardest hit by storm

MIAMI - While much of Miami-Dade County appears to have emerged unscathed from Hurricane Matthew, new evidence from an unmanned aircraft system (UAS) indicates that the storm had significant impact on a portion of the shore along Miami Beach, according to marine scientists.

Airborne Response, a Miami Beach-based UAS startup company, launched a drone aircraft on Wednesday, October 5, and again on Sunday, October 9 to capture photos of various sections of Miami Beach both before and after the storm.

While much of the beach appears to be minimally affected, substantial beach erosion is apparent behind Indian Beach Park at the 4600 block of Collins Avenue. That location is the site of the ongoing Miami Beach Erosion Control and Hurricane Protection project spearheaded by the U.S. Army Corps of Engineers.

“When comparing the before and after images of the project site, we see certain sections with a very pronounced difference in coastline,” says Nelson Melo, Director of Marine Sciences for Altametry. “We estimate around 15 meters of erosion, and 23 meter of deposit in the images we reviewed. This estimation takes into account the tide difference based on the time each photo was taken."

Altametry is a Miami-based UAS company that also specializes in scientific analysis of imagery from drones. Altametry and Airborne Response work closely together on a variety of UAS-related projects. “At beach coastlines, the sediment generally moves with waves as a function of the wave height, period, bathymetry, and wave incident angle,” according to Melo. “The after photo clearly shows beach erosion on the left segment, and accumulation in the right segment. This is known as ‘redistribution’ of the sediment.”

This type of scientific analysis is precisely the reason many organizations are now turning to drones, says Christopher Todd, CEO and founder of Airborne Response.

“In the past, these types of analyses were largely dependent on either aircraft or satellite imagery — both of which are extremely expensive,” says Todd. “Unmanned aircraft systems now provide a quick and cost-effective method for capturing aerial imagery that was previously cost prohibitive for many organizations.” 1) IMAGERY VIDEO LOOP: erosion@airborneresponse.com 2) HIGH RESOLUTION PHOTOS AVAILABLE UPON REQUEST
