One of most advanced groundwater technologies
|
CFEST (Coupled Fluid, Energy, Solute Transport) is a three-dimensional finite-element code for analyzing isothermal and non-isothermal groundwater flow, energy, and solute transport in groundwater systems. CFEST code can be used to:
- Simulate both confined and unconfined aquifer systems.
- Conduct coupled and decoupled groundwater flow and solute transport analysis
in a constant-fluid-density environment.
- Perform density-dependent flow and transport evaluations.
- Interfaced integrated grid generation capabilities.
- Model external model boundary, rivers, lakes, faults, and other features are
modeled in “natural shapes” without distortion.
- Three-dimensional elements are generated internally which reduces manual
labor and ensures the continuity of all interfaces of three-dimensional brick
elements with adjoining elements.
- Interfaced GIS (Geographical Information System) and 3D plotting/animation
tools assist in easy-input file generation and results evaluation.

Illustrative samples of CFEST Models:
|
| Long Island Groundwater Reservoir Model (1976) (a) 3d model; (b) Variable layers, & (3) Input Displays Long Island was simulated on small computer with 170 K memory as well as on CRAY computer |
 |
| EPA (Superfund) San Gabriel Basin – 170 Sq. Mile area – CFEST was 3D model of whole basin. CFEST results were used for OU boundaries and ROD negotiations |
