Computer Codes

1. MODFLOW
2. MODFLOWP (Hill, 1992).
3. MOC3D (Three-DimensionalMethod-of-Characteristics Ground-Water Flow and Transport Model).
4.  MT3DMS (Modular 3-D Multi-Species Transport Model for Simulation of Advection, Dispersion, and Chemical Reactions of Contaminants in Groundwater Systems).
5. RT3D (Multi-Species Reactive Flow and Transport Simulation Software).
6. HST3D (Heat and Solute Transport in Three-Dimensional Groundwater Systems).
7. FEMWATER (Three-Dimensional Finite Element Model of Water Flow Through Saturated-Unsaturated Media).
8. Random-Walk (Random-Walk Solute TransportModel for Selected Groundwater Quality Evaluations).
9. GMS (Groundwater Modeling System). GMS is a software pre-processor, post-processor, and graphic user interface (GUI) implementation of a number of public domain groundwater modeling computer codes, which include FEMWATER, MODFLOW, MODPATH, MT3DMS, RT3D, UTCHEM, and PEST. It was developed by the U.S. Army Engineer Research and Development Center for use by governmental agencies. It is available as a commercial software.
10. SWAT (Soil and Water Assessment Tool). SWAT (Arnold and Fohrer, 2005; Neitsch et al., 2005) is a basin scale, continuous time model designed to predict the impact of management on water, sediments, and agricultural chemical yields in ungaged watersheds. Major model components include weather, hydrology, soil temperature and properties, plant growth, nutrients, pesticides, bacteria and pathogens, and land management. In SWAT, a watershed is divided into multiple sub-watersheds, which are then further subdivided into hydrologic response units that consist of homogeneous land use, management, and soil characteristics. SWAT is a public domain code supported by the U.S.D.A. Agricultural Research Service at the Grassland, Soil and Water Research Laboratory.
11. HYDRUS (Movement of Water, Heat, and Multiple Solutes in Variably Saturated Media).
12. FEFLOW (Finite Element Subsurface Flow and Transport Simulation System).
13. PEST (Model-independent parameter estimation).
14. SUTRA (Model for 2D or 3D Saturated-Unsaturated, Variable-Density Ground-Water Flow, with Solute or Energy Transport).
15. SEAWAT (Computer Programfor Simulation of Three-Dimensional Variable-Density Ground-Water Flow).

24. BIOPLUME. BIOPLUME is a two-dimensional computer code for simulating contaminant transport of a single and multiple hydrocarbons with oxygen-limited and reactant-limited bioreactions (Rafai et al., 1998), developed by EPA. Its transport code is based on the USGS MOC.
25. NAPL Simulator. The NAPL Simulator is an EPA three-dimensional computer code based on Hermite collocation finite element discretization (Guarnaccia et al., 1997).
26. UTCHEM (University of Texas Chemical Compositional Simulator). Originally a three-dimensional finite difference model for multiphase flow, multicomponent transport and chemical flooding, this code has been modified to become a general purpose NAPL simulator (University of Texas, 2000).
