  • Sea Level Rise Vulnerability (Confidence) for Lanai at 3ft above MHHW

    Metadata Updated: November 12, 2020

    This map shows levels of confidence of coastal flooding (inundation) around the island of Lanai in the State of Hawaii due to 3 feet (0.914 m) of sea level rise above mean higher high water (MHHW). Blue areas denote a high confidence of inundation, orange areas denote a low confidence of inundation, and unshaded areas denote a high confidence that these areas will be dry at this water level. In this application, 80% is considered a high degree of confidence such that, for example, the blue areas denote locations that may be correctly mapped as "inundated" more than 8 out of 10 times. Areas with a low degree of confidence represent locations that may be mapped correctly (either as inundated or dry) less than 8 out of 10 times.

    Confidence mapping is a fairly complicated procedure that is explained in detail in "Mapping and Portraying Inundation Uncertainty of Bathtub-Type Models" available at "http://www.jcronline.org/doi/abs/10.2112/JCOASTRES-D-13-00118.1". In short, the method includes the uncertainty in the LiDAR-derived elevation data (root mean square error, or RMSE) and the uncertainty in the modeled tidal surface from the NOAA VDATUM MHHW (RMSE). This uncertainty is combined and mapped to show that inundation extent is not really a hard line, but rather a zone with greater and lesser chances of getting wet.

    Data produced in 2014 by NOAA Office for Coastal Management (OCM). These data do not consider future changes in coastal geomorphology and natural processes such as erosion, subsidence, or future construction. These data do not specify timing of inundation and are not appropriate for conducting detailed spatial analysis. The entire risk associated with the results and performance of these data is assumed by the user. These data should be used strictly as a planning reference and not for navigation, permitting, or other legal purposes.
