Hawaii Map Series of Storm Surge Inundation for the Ocean Hazards Database

This database consists of a series of maps showing the estimated inundation of Hawaii shorelines caused by hypothetical category 1, 2, 3, and 4 storm surges. Individual maps show inundation across mile-long sections of Hawaii state routes on the islands of Hawaii, Maui, Molokai, Oahu and Kauai previously identified for their vulnerability to the effects of climate change as part of the Statewide Coastal Highways Project Report. Mileposts are identified by Brandes et al. (2019). State of Hawaii Department of Transportation (HDOT) state routes and Oahu street centerline datasets are acquired from HDOT (2017) and HOLIS, C&CH (2017). Storm surge maximum of maximum (MOM) inundation extents are determined by the NOAA National Hurricane Center Storm Surge Unit using the Sea, Lake and Overland Surges from Hurricanes (SLOSH) model and are reported in Zachry et al. (2015). Please read ‘Description-Map of Storm Surge Inundation.docx’ for detailed information.
