Abstract


Hurricane Joaquin formed in the SW Atlantic on September 28, 2015 and several
days later made landfall in the Bahamas as a CAT 4 hurricane. The island of San
Salvador sustained significant infrastructural damage.  A rapid assessment of the
storm impact on the coast was undertaken in January 2016 by a team of
researchers from multiple institutions.  Smith College sent a team of students to
capture low altitude imagery via drone.  Visible spectrum imagery was processed
to produce orthophotos and digital surface models to complement and enhance
other assessment methods including ground surveys and ground-penetrating
radar.  Field data are corroborated and enhanced with measurements from UAV
derived 3D point clouds (see Figure 1).

 

Methods and result will be shared with Bahamian officials to assist planning
for future hurricanes and sea level rise.
