Hurricane-Induced Coastal Erosion Hazards

Access map layers showing predictions of how sandy beaches along the U.S. Gulf of Mexico and Atlantic coastlines will respond to the direct landfall of category 1–5 hurricanes.

This interactive map displays hurricane-induced coastal erosion hazards for sandy beaches along the U.S. Gulf of Mexico and Atlantic (Florida to New York) coastlines. The analysis is based on a storm-impact scaling model that uses observations of beach morphology combined with sophisticated hydrodynamic models to predict how the coast will respond to the direct landfall of category 1-5 hurricanes. Hurricane-induced water levels resulting from both surge and waves are compared to beach and dune elevations to determine the probabilities of three types of coastal change: collision (dune erosion), overwash, and inundation.

Features:

  • Identifies Gulf of Mexico and Atlantic coastline likely to experience extreme and potentially hazardous erosion during a hurricane
  • Compares hurricane-induced water levels to beach and dune elevations to determine the probability of coastal change
  • Examines small-scale variability for a specific area
  • Provides supporting morphology and water level data
