Title:
Nearshore parametric wave setup future projections (2020-2050) for the North and South Carolina coasts
Abstract:
This dataset presents alongshore wave setup timeseries for the North and South Carolina coastlines. Wave setup was modelled using parameterization for open coast sandy beaches as presented in Stockdon and others (2006). The parameterization relates onshore wave setup to offshore wave conditions and beach characteristics. Wave conditions were extracted at approximately the 10 m depth contour and reverse shoaled to the deep-water condition. These data were then matched to cross-shore transects spaced at approximately 1 km along the coastline. Beach slope at these transects were extracted from lidar (Doran and others, 2017) and temporally averaged across all available datasets. Waves were modelled using a global WAVEWATCHIII model forced by atmospheric forcing from the Coupled Model Intercomparison Project (CMIP6) future period data. This dataset provides information on how water setup is expected to change moving towards the future. The methodology used to produce this dataset is further detailed in Parker and others (2023). Data are provided for 6 CMIP6 models from the HighResMIP project (Haarsma and others, 2016). Output includes 1-hour wave setup provided at approximately 1,600 alongshore transects at approximately 1-5 km resolution. Data are available as csv files for each transect location and are bundled by state.

    Date: 01-Feb-2021 (process 1 of 7)
    Projected wave data from CMIP6 forced WAVEWATCHIII wave model were obtained. Data sources used in this process:
    • WW3
    Date: 01-Apr-2021 (process 2 of 7)
    The North and South Carolina wave data were matched to transects along the southeast Atlantic coastline. Transects were spaced at approximately 1-5 km along the coast extending in the cross-shore direction.
    Date: 01-May-2021 (process 3 of 7)
    Beach morphology information was obtained using the lidar derived dataset of Doran and others (2017). Beach slope information was linearly interpolated to the cross-shore transects for all available times and then temporally averaged at each location. Beach slopes were then spatially smoothed using a Hanning filter following the method of Doran and others(2015). Data sources used in this process:
    • lidar
    Date: 01-Jul-2021 (process 4 of 7)
    Wave setup was calculated at each transect using the parametrization of Stockdon and others (2006) for every hourly timestep as described in Parker and others (2023).
    Date: 01-Feb-2022 (process 5 of 7)
    Wave setup files were packaged for data release.
    Date: 13-Mar-2023 (process 6 of 7)
    Metadata was modified to include doi# and full citation for Parker and others (2023) Cross Reference. No data information was changed.

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

  1. How well have the observations been checked?
    Wave setup presented in this dataset is approximate and based on parameterization that relates a limited set of inputs to wave setup experienced at the coast. Wave setup is expected to be dominated by error in the utilized parametrization. Stockdon and others, (2006) assessed the accuracy of the utilized parameterization as having a root mean square error of 21 cm and accuracy of this dataset is expected to be of a similar magnitude.
  2. How accurate are the geographic locations?
    Data are concurrent with specified transect locations.
  3. How accurate are the heights or depths?
    Wave setup is projected for the future period so cannot be assessed for accuracy against observations.
  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 rest of the metadata record carefully for additional details.
  5. How consistent are the relationships among the observations, including topology?
    Data have undergone quality checks and fall within expected/reasonable ranges.

How can someone get a copy of the data set?
