Title:
Projected coastal flooding depths for 1-, 20-, and 100-year return interval storms and 0.00, +0.25, +0.50, +1.00, +1.50, +2.00, and +3.00 meter sea-level rise scenarios in the Hawaiian Islands (ver. 1.1, September 2024)
Abstract:
This data release provides flood depth GeoTIFFs based on sea-level rise and wave-driven total water levels for the coast of the most populated Hawaiian Islands of Oahu, Molokai, Kauai, Maui, and Big Island. Oceanographic, coastal engineering, ecologic, and geospatial data and tools were combined to evaluate the increased risks of storm-induced coastal flooding in the populated Hawaiian Islands due to climate change and sea-level rise. We followed risk-based valuation approaches to map flooding due to waves and storm surge at 10-m2 resolution along the coastlines for annual (1-year), 20-year, and 100-year return-interval storm events and +0.25 m, +0.50 m, +1.00 m, +1.50 m, +2.00 m, and +3.00 m sea-level rise scenarios.

Why was the data set created?

These flood extent files were created to evaluate the increased risks of storm-induced coastal flooding in the most populated Hawaiian Islands Oahu, Molokai, Kauai, Maui, and Big Island due to climate change and sea-level rise. The data are intended to provide a spatially explicit, rigorous valuation of how, where, and when climate change and sea-level rise increase coastal storm-induced flooding to help identify areas where management and/or restoration could potentially help reduce the risk to, and increase the resiliency of, the coastal communities in Hawaii. The data can be used with geographic information systems (GIS) software for research purposes. The methods follow a sequence of steps derived from Storlazzi and others (2019, 2021) and Reguero and others (2021) that integrate physics-based oceanographic and coastal engineering modeling, along with ecologic and geospatial data and tools, to quantify the role of climate change and sea-level rise in increasing coastal flooding hazards.

    The nearshore wave time series (hourly data from 2020 to 2050) were fit to a General Pareto Distribution (GPD) selecting the maxima using the peak exceedances over a threshold method, to obtain the significant wave heights associated with the annual (1-year), 20-year, and 100-year storm return periods. Given the differences between GCMs, the GPDs for each GCM were adjusted using a common, unique threshold, which was obtained as the minimum threshold obtained for each extreme value model estimated for each GCM individually. The results correspond to the ensemble, as the mean value for each return period. The corresponding annual (1-year), 20-year, and 100-year storm return period extreme water levels for the location were calculated similarly, from the nearest GTSM output point.

    The return value significant wave heights and associated peak periods, estimated through a linear regression on the wave time series from SWAN, were then propagated over the coral reefs with corresponding return value sea levels from GTSM along the 100-m spaced shore-normal transects using the numerical model XBeach (Roelvink and others, 2009; XBeach, 2016). XBeach generated forcing wave time series for each modeled storm return period, which were reused as inputs for modeling six sea-level rise scenarios (+0.25 m, +0.50 m, +1.00 m, +1.50 m, +2.00 m, and +3.00 m sea-level rise) under the same return period.

    XBeach outputs, extracted at the 0.5 m depth, were used to calculate water level and infragravity waves time series used to force SFINCS. SFINCS is a super-fast flooding model that dynamically calculates two-dimensional compound flooding maps in coastal areas (Leijnse and others, 2021). In this project, SFINCS was coupled with XBeach to compute two-dimensional flood maps for all the islands, storm return periods, and sea-level rise scenarios. Person who carried out this activity:

    All originating GeoTIFFs for each data layer were imported into ArcMap and converted from netCDF (.nc) to raster (.tif) files. These outputs were clipped to fit the land area of each island. The geoTIFFs were exported from ArcMap for all combinations of seven sea-level rise scenarios (0, 0.25, 0.5, 1.0, 1.5, 2.0 and 3.0 m), 3 storms (1-year, 20-year, and 100-year return period coastal events) for a total of 21 scenarios. Final shapefiles were separated by island (Projections_FloodDepths_*Island*.zip) for file-size considerations. GeoTIFFs are further organized by storm scenario return period ('RP').

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    Attribute values are model-derived extents of flood projections due to plausible sea-level rise and future storm conditions and therefore cannot be validated against observations.
  2. How accurate are the geographic locations?
    Data are concurrent with topobathymetric digital elevation model (DEM) locations.
  3. How accurate are the heights or depths?
    Model-derived data are accurate within the flood potential layers, indicative of total uncertainty from elevation data sources, model processes and contributing data, and vertical land motion. This value is spatially variable and dependent on scenario.
  4. Where are the gaps in the data? What is missing?
    Dataset is considered complete for the information presented as described in the abstract. Users are advised to read the metadata record carefully for additional details.
  5. How consistent are the relationships among the observations, including topology?
    Data have undergone quality checks and meet standards.

How can someone get a copy of the data set?
