"Aqueous Modeling at the Savannah River National Laboratory"
The Atmospheric Technologies Group (ATG) at Savannah River National Laboratory (SRNL) is tasked with responding to any potential release of hazardous material to both the atmosphere and water ways. To support this emergency response, ATG has developed a one-dimensional advective-diffusion code to predict transport in the streams and waterways, STREAMII. This code currently has many user friendly options, including predefined release locations and the option to include rainfall runoff, which are all easily accessible through the graphical user interface (GUI). In addition to the one-dimensional code, a three dimensional hydrodynamic model, ALGE3D, has also been developed. ALGE3D solves the momentum, mass, and energy conservation equations to predict the movement and dissipation of thermal or dissolved chemical plumes discharged into cooling lakes, rivers, and estuaries. ALGE3D is a dynamic code that is capable of modeling flow in complex terrain including tidal estuaries with large areas of wetting and drying. Improvements to ALGE3D are underway to include particulate tracer simulation with sedimentation effects and the development of a database of locations for quick deployment in an emergency response situation.
