High-tide flooding is an increasingly frequent occurrence in coastal areas around the Pacific. The NASA Pacific Flooding Analysis Tool was developed to facilitate decision-relevant assessments of how sea-level rise and other factors will affect the frequency and extent of high-tide flooding for Pacific Islands. Users can:

  • View sea-level observations and assess past high-tide flooding frequency.
  • Assess amounts of sea-level rise expected for various amounts of end-of-century global warming.
  • View future changes in high-tide flooding frequency for various amounts of sea-level rise.
  • View maps showing the extent of future high-tide flooding for select locations.

The Pacific Flooding Analysis Tool was developed with funding from the NASA Sea Level Change Team by scientists at the University of Hawaii Sea Level Center. The flooding frequencies are based on the methods of Thompson et al. (2021), while the maps of flooding extent were produced by scientists at University of Colorado Boulder and Virginia Tech using methods similar to those in N-SLCT et al. (2023).
