Sea Level Rise Inundation Risk for Honolulu

October 1, 2014

PacIOOS is one of eleven regional observing programs in the U.S. that are supporting the emergence of the U.S. Integrated Ocean Observing System (IOOS®) under the National Oceanographic Partnership Program (NOPP).


PacIOOS just released a new page titled, “Sea Level Rise Inundation Risk” under the “Projects” tab highlighting a project funded by the NOAA Coastal Storms Program. This project aims to fulfill the need for Hawaiʻi-specific information regarding the impacts of sea level rise on coastal inundation zones. The project focuses on the urban corridor of Honolulu, from Diamond Head to Pearl Harbor, representing the majority of the state’s commercial and industrial sectors. The area was also chosen because of its high density, large population, major infrastructure, and high economic activity.

The study identified potential changes in exposure and risk to coastal inundation hazards (such as hurricanes, tsunamis and storm inundation) as a result of projected sea level rise. Through targeted outreach and the web viewer on PacIOOS’ website, the results of this research can serve as a decision-support tool for facilitating science-based planning and policy.
