Abstract
A Geospatial Framework for Hydrodynamic Modeling of a Coastal Estuary Track: Environmental Management Author(s): James Bollinger, Larry Koffman, David Hayes, Alfred Garrett 3D hydrodynamic models are used by the Savannah River National Laboratory (SRNL) to simulate the transport of thermal and radionuclide discharges in coastal estuary systems. Development of such models requires accurate bathymetry, coastline, and boundary condition data in conjunction with the ability to rapidly discretize model domains and interpolate the required geospatial data onto the domain. To facilitate rapid and accurate hydrodynamic model development, SRNL has developed a pre- and postprocessor application in a GIS framework to automate the creation of models using existing geospatial data. This automated capability allows development of very detailed models to maximize exploitation of available surface water radionuclide sample data and thermal imagery. This modeling approach was utilized to simulate the transport of tritium oxide from the Savannah River to the adjoining coastal estuary near Savannah, Georgia. Construction of the model domain and postprocessing of the model output in a GIS environment will be discussed.
