Ocean Hazards Database (OHD) for the State of Hawaii Statewide Coastal Highway Program Report

Summary:

This Ocean Hazards Database (OHD) contains all relevant geographic information system (GIS) layers, maps, measures, interpretations, and rankings from the Ocean Hazards Classification Scheme (OHCS) assessment of 302 mileposts and points of interest across coastal state routes in Hawaii. As a part of the State of Hawaii Department of Transportation Statewide Highway Shoreline Program Report, the OHCS assesses and ranks shoreline roadway vulnerability to historical sea-level rise rates (in/yr), projected sea-level rise rates by 2050 and 2100 (in/yr), mean tidal ranges (ft), maximum annually recurring peak wave periods (sec) and significant wave heights (ft), mean projected shoreline change rates (ft/yr) and coastal armoring, historical and hypothetical tsunami flow depths (ft), and hypothetical category 1-4 storm surge inundation heights (ft). OHCS ranking criteria and methods are described in Chapter 3 of the State of Hawaii Statewide Coastal Highway Program Report (2019). OHD materials are organized into coastal highway digital elevation models, ocean hazard map packages, ocean hazard supplementary maps, and ocean hazard supplementary tables.
