The Heat- and Solute-Transport Program (HST3D) simulates ground-water flow and associated heat and solute transport in three dimensions. Over the years since the release of Versions 1.0 through 1.4, ...

6. 3DADE Model: Evaluates analytical solutions for two- and three-dimensional equilibrium solute transport [USDA_ARS_3DADE]
3DADE is a Fortran computer program for evaluating a series of analytical solutions of the 3-Dimensional Advection-Dispersion Equation. The analytical solutions pertain to three-dimensional solute ...

7. CFITM Model: Estimates CDE solute transport parameters (v, D) from analysis of column breakthrough data [USDA_ARS_CFITM]
Predictions of solute transport in the field are generally based upon convective-dispersive type transport equations. The one-dimensional form of this equation contains two parameters which must be ...

8. CHAIN Model: Evaluates analytical solutions for convective-dispersive transport of solutes subject to consecutive decay chain reactions (up to 4 solutes) [USDA_ARS_CHAIN]
Problems of solute transport involving sequential first-order decay reactions frequently occur in soil systems. Examples are the migration of radionuclides, in which the chain members form a first-order ...

9. CXTFIT Model: Estimates parameters in several equilibrium and non-equilibrium transport models from laboratory or field tracer experiments [USDA_ARS_CXTFIT]
Successful predictions of the fate and transport of solutes in the subsurface hinges on the availability of accurate transport parameters. We modified and updated the CXTFIT (version 1.0) code of ...

10. N3DADE Model: Nonequilibrium 3-Dimensional Advection-Dispersion Equation [USDA_ARS_N3DADE]
This research report documents the Fortran program N3DADE (Nonequilibrium 3-Dimensional Advection-Dispersion Equation) which may be used to evaluate analytical solutions described by Leij et al. [1993]. ...

11. STANMOD Model (STudio of ANalytical MODels) [USDA_ARS_STANMOD]
