In recent years, rising sea levels have threatened critical infrastructure and cultural assets at Puʻuhonua o Hōnaunau National Historical Park thus motivating the park to make adaptive decisions in managing these key resources. To support the development of decision support tools for sea level rise preparedness, the U.S. Geological Survey (USGS) Coastal National Elevation Database (CoNED) Applications Project has created an integrated 1-meter topobathymetric digital elevation model (TBDEM) for Puʻuhonua o Hōnaunau National Historical Park. This dataset was developed in collaboration with the University of Hawaii- Mānoa Sea Level Center, Department of Interior Pacific Island Climate Adaptation Science Center, and Puʻuhonua o Hōnaunau National Historical Park. High-resolution coastal topobathymetric data are required to characterize flooding, storms, and sea-level rise inundation hazard zones and other earth science applications, such as the development of wave and storm surge models. This data release was funded by a Supplemental Proposal to Grant No. G15AP00140 by the University of Hawaii- Mānoa Sea Level Center from the Department of Interior Pacific Island Climate Adaptation Science Center and the USGS Coastal and Marine Hazards and Resources Program.
