Studying flood hazards in San Juan, Puerto Rico

Release Date:

USGS scientists from Pacific Coastal and Marine Science Center, along with with NOAA, the University of Puerto Rico-Mayaguez, and Arrecifes Pro Ciudad, are using video imagery and wave measurements to study flood hazards in San Juan, Puerto Rico.

USGS scientists have installed video cameras and oceanographic instruments off San Juan, Puerto Rico, to better understand how waves move across coral reefs and cause flooding on tropical shorelines. Their work is part of a study funded by USGS after Hurricanes Irma and Maria. The offshore instruments measure wave heights and speeds; the onshore video cameras show where waves break on the reef and how high they run up on the shore. USGS is collaborating with NOAA, the University of Puerto Rico-Mayaguez, and Arrecifes Pro Ciudad to support reef-restoration efforts in the Isla Verde Coral Reef Marine Reserve and reduce flooding hazards to San Juan and its international airport.
