Thompson 20230810 raster digital data U.S. Geological Survey data release doi:10.5066/P986ZR6B St. Petersburg, FL U.S. Geological Survey - St. Petersburg Coastal and Marine Science Center 2023a https://doi.org/10.5066/P986ZR6B The effects of interior headland restoration on estuarine sediment transport processes are assessed through process-based numerical modeling. Three proposed interior headland restoration scenarios in the Grand Bay estuary (Mississippi/Alabama) are modeled using Delft3D (developed by Deltares) to understand impacts on suspended sediment concentrations, bed level morphology and sediment fluxes under present-day conditions and a sea level rise of 0.5 meters (m). Delft3D model output of suspended sediment concentrations (SSC), sediment fluxes, initial and final bed levels, and hydrodynamic data are included in this dataset. Model output from six scenarios (comprised of three restoration (R) alternatives and two sea level (SL) conditions) as forced by 18 climatological wind and wave forcing conditions are included in this data release (Jenkins and others, 2023a). For further information regarding model input generation, set up, and analysis, refer to Jenkins and others (2023b). Data were generated by the Delft3D model as output to assess effects of interior headland restoration. Appropriate use of this data includes the assessment of morphological, sediment process, and hydrodynamic differences due to the placement of restored features and sea level for the Grand Bay estuary. This dataset consists of Federal Geographic Data Committee (FGDC) metadata record (.txt and .xml) and Network Common Data Form (NetCDF, .nc) files (under six scenarios: three restoration alternatives (R0, R1, and R2) and two sea level conditions (S0 and S1), as forced by 18 climatological wind and wave forcing conditions) containing the following variables: coordinates of the model grid (Easting and Northing) and hourly model resultant suspended sediment concentrations (SSC, in kilograms per liter) of five sediment classes (13, 48, 100, 136 and 278 micrometers) for the one-year mormerge (Roelvink, 2006) scenario. 20200101 20210101 model simulation Complete None planned -88.7000 -87.7000 30.5000 30.0000 ISO 19115 Topic Category geoscientificInformation structure environment elevation oceans USGS Metadata Identifier USGS:6ec808a6-6342-4634-a1d2-206a2dc0795b USGS Thesaurus modeling digital elevation models estuarine processes coastal processes sediment transport sea-level change tides (oceanic) hydrodynamics remediation None U.S. Geological Survey USGS St. Petersburg Coastal and Marine Science Center Coastal and Marine Hazards and Resources Program CMHRP SPCMSC Restoration Sediment Concentrations Sediment Flux Headlands Waves Geographic Names Information System (GNIS) Gulf of Mexico Alabama Mississippi Grand Bay None Public domain data from the U.S. Government are freely redistributable with proper metadata and source attribution.

Jenkins, R.L., Passeri, D.P., Smith, C.G., Thompson, D.M., and Smith, K.E.L. 2023 Journal Frontiers in Marine Science Unknown 2023b https://doi.org/10.3389/fmars.2023.1217830 Roelvink, J.A. 200602 Journal Coastal Engineering Volume 53, Issues 2-3 Online Elsevier BV Pages 277-287 https://doi.org/10.1016/j.coastaleng.2005.10.015 A deterministic validation simulation was run for the period of 2017/01/03 through 2017/01/23. Model output was evaluated against observed waves and water levels during that time-period and the model results accurately reproduced the observed conditions. More information about model accuracy and validation is outlined in Jenkins and others (2023b). The model’s resultant suspended sediment concentrations (SSC, in kilograms per liter) are of the five sediment classes from the mormerge Delft3D run simulating the period 2020/01/01 through 2021/01/01 of the hourly SSC for each model cell (Roelvink, 2006). These are the complete model resultant SSC (kilograms per liter) of five sediment classes from the mormerge Delft3D run simulating the period 2020/01/01 through 2021/01/01 (Roelvink, 2006). SSC are included as produced under all six scenarios (Jenkins and others, 2023b) and 18 climatological wind and wave forcing conditions. This dataset is considered complete for the information presented, as described in the abstract section. Users are advised to read the rest of the metadata record carefully for additional details. Within the Delft3D model, the horizontal coordinates were projected to the North American Datum of 1983 (NAD83) Universal Transverse Mercator (UTM) Zone 16 North (16N) coordinate system with an estimated resolution of 5m. Within the Delft3D model, the vertical positions were projected to the North American Vertical Datum of 1988 (NAVD88) with an estimated resolution of 0.01 m. The Delft3D model simulated process-based probabilistic morphological change resultant from hydrodynamic action (including waves) and sediment transport. Model setup is outlined in Jenkins and others (2023b). Boundary conditions in the form of a wind and wave climatology and harmonic water level boundary forcing are also outlined in Jenkins and others (2023b). Simulated resultant suspended sediment concentrations (SSC, in kilograms per liter) of five sediment classes were output every 60 minutes (hourly) as produced by each of 18 climatological wind and wave forcing bins, under six scenarios: three restoration alternatives (R0, R1, and R2) and two sea level conditions (SL0 and SL1). 20230222 Robert L Jenkins U.S. Geological Survey, SOUTHEAST REGION Physical Scientist mailing address

St. Petersburg FL 33701 US 727-502-8138 727-502-8182 rljenkins@usgs.gov Model hourly suspended sediment concentrations (SSC) were extracted in MathWorks MATLAB (R2015a) with functions included in the OpenEarth toolbox (provided by Deltares; https://publicwiki.deltares.nl/display/OET/Tools). The resulting wave variables from the model grid were then packaged into a NetCDF file (.nc) using the functions available in MATLAB for inclusion in this data release (Jenkins and others, 2023a). This step was completed for six scenarios: three restoration alternatives (R0, R1, and R2) and two sea level conditions (S0 and S1), and were packaged into an individual data zip, per scenario. Furthermore, the 18 climatological wind and wave forcing bins per scenario were divided into individual data files (.nc), as a measure to reduce file size, as follows: bins 1 to 5 (1thru5), bins 6 to 10 (6thru10), bins 11 to 15 (11thru15), and bins 16 to 18 (16thru18).
