Thompson 20180828 raster digital data U.S. Geological Survey Data Release doi:10.5066/P9SS1DJW St. Petersburg, FL U.S. Geological Survey https://doi.org/10.5066/P9SS1DJW The numerical model Delft3D (developed by Deltares) was developed to evaluate the potential effects of proposed navigation channel deepening and widening in Mobile Harbor, Alabama (AL). The Delft3D model setup requires the input of a merged topographic and bathymetric elevations, a wave climate based on significant wave heights, peak wave period and mean wave direction, and a tidal-time series. The model was validated by comparing model outputs from deterministic runs with observations of water levels and velocities. The validated model was used to simulate scenarios of existing conditions and proposed with-project conditions (for example, channel deepening and widening). Simulations were performed for one year (the year 2010) and ten years, with and without 0.5 meters (m) of sea level rise. Model inputs and outputs in the form of topography and bathymetry for the scenario runs as well as output water levels and velocities for the deterministic runs are provided in this data release. For further information regarding model input generation and visualization of model output topography and bathymetry, refer to USGS Open-File Report 2018-1123. These data were generated for the Delft3D model to evaluate the potential effects of proposed navigation channel deepening and widening in Mobile Harbor, AL. Deterministic_20151209_20151211.zip is a dataset that consists of Federal Geographic Data Committee (FGDC) metadata and a Network Common Data Form (NetCDF) file containing the following variables: coordinates of the model grid (Easting and Northing) and hourly u (through-channel) and v (cross-channel) water flow velocities, in meters/second, for the deterministic scenario run from December 09, 2015 through December 11, 2015. 20180828 publication date Complete As needed -88.4612126529462 -87.6748359827091 30.697486 29.969949 USGS Metadata Identifier USGS:68db5751-f56a-4984-aca9-c132e1c58c6c None U.S. Geological Survey USGS St. Petersburg Coastal and Marine Science Center SPCMSC morphologic change estuaries coastal marine sediment transport ISO 19115 Topic Category oceans elevation geoscientificInformation USGS Thesaurus marine geology geomorphology topography bathymetry coastal ecosystems estuarine ecosystems digital elevation models sea-level change ocean processes sediment transport Geographic Names Information System (GNIS) Content Gulf of Mexico Alabama North America United States of America Mobile Bay None.

These are the complete resultant hourly u (through-channel) and v (cross-channel) water flow velocities from the deterministic scenario run from 2015/12/09 through 2015/12/11. 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. These u (through-channel) and v (cross-channel) velocities are the resultant hourly u (through-channel) and v (cross-channel) velocities from the deterministic scenario run from 2015/12/09 through 2015/12/11. Within the Delft3D model, the coordinates are in Universal Transverse Mercator (UTM). Vertical datum is in the North American Vertical Datum of 1988 (NAVD88) with an estimated resolution of 0.01 m. The Delft3D model simulates morphologic change that results from hydrodynamic impacts and sediment transport. Model setup is outlined in USGS Open-File Report 2018-1123. Boundary conditions in the form of a wave climatology and tidal time-series are outlined in USGS Open-File Report 2018-XXXX. Simulated u and v velocities are output hourly. 2018 Davina Passeri U.S. Geological Survey Research Civil Engineer mailing and physical address
