Description of this data

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 raise 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.

Digital Elevation Models (DEM) contains GIS layers for nearshore topographic and bathymetric elevations on the islands of Hawaii, Maui, Molokai, Oahu, and Kauai.

Map Packages contain GIS layers and mapping layouts for the assessment and projection of sea-level rise inundation, maximum annually recurring wave characteristics, projected shoreline change, storm surge inundation, and offshore bathymetry.

Supplementary Tables contain OHCS measure results and rankings for 302 mileposts and points of interest across coastal state routes in Hawaii. Representative dataset references are included in table footnotes.

Supplementary Maps contain image files of nearshore and offshore transects, sea-level rise inundation extents, maximum annually recurring wave characteristics, projected shoreline changes, and storm surge inundation extents for 302 mileposts and points of interest across coastal state routes in Hawaii.

This project was funded by the Hawaii Department of Transportation, HWY-06-16, entitled "Statewide Highway Shoreline Protection Program Study Update."
