Category	Contaminant transport (3D)
Publisher	Oak Ridge National Laboratory
Platform	DOS
Status	Public domain
Description	AT123D is a 1D, 2D and 3D analytical contaminant transport model including advection, dispersion, adsorption and decay. Links to SESOIL for contaminant mass to groundwater quantities entering the aquifer from the unsaturated zone. Computes the spatial-temporal concentration distribution of wastes in the aquifer system and predicts transient spread of the contaminant plume through the groundwater aquifer. Models homogeneous, anisotropic aquifer with uniform, stationary regional flow. The program allows for retardation and first-order decay. Simulation of a variety of source configurations (including point source, line source, and areal source) and boundary conditions is possible, and longitudinal as well as horizontal and vertical transverse dispersion can be input independently. The model calculates concentration distribution in space and time. The program comes with an IGWMC prepared shell (PREAT123) for data input and editing, program execution, and post-processing. Complete model results are output to a text file, and special files are created for graphical post-processing with commercial contouring software. Contains source code, executable image, and example data sets.
