Atrans - Version A - 3D Analytical Software
ATRANS A 3D analytical solution for transport from a patch boundary condition with time varying concentration.
The solution considers the following transport processes: advection, dispersion, sorption, and first-order transformation reactions. The solution assumes the groundwater flow field is steady and uniform.
The ATRANS package of solutions can represent four inflow concentration histories:
- Constant concentration;
- Exponentially decaying concentration;
- Arbitrary inflow concentration specified as a set of points; and
- Arbitrary inflow concentration specified as a set of steps.
ATRANS for Microsoft Excel - Updated for MS Office 2010
Marinko Karanovic has developed an Excel version of ATRANS. All parameters are input within the spreadsheet and output in either graphical or tabular presentation for quick model runs.
Both ATRANS packages include complete documentation, Fortran source codes, and executable codes that run within DOS boxes (Command Prompt).
