Sites with source code or working software

These are the most extensive sites.

• USGS Ground-Water Software
• Waterways Experiment Station (US Army Corps of Engineers)
• USSL Models
• USGS Water Resources Applications Software via the USGS Water Resources page. Too many programs to list.
• Ground-Water and Vadose Zone Models/Manuals at Center for Subsurface Modeling Support at Kerr Lab. 13 different programs are available from this site including MT3D and BIOPLUME II.
• Models at Databases and Software at Environmental Protection Agency WWW Server.

  More sites with "downloadable" software

• University of the Free State New
• PEST - Parameter estimation software.
• FLOWTHRU displays groundwater flow patterns in an aquifer near a surface water body. Although written with shallow lakes in mind, the program also applies to wetlands, rivers, streams, canals and channels. The primary uses of FLOWTHRU are (i) for determining the depths of groundwater capture zones near shallow water bodies (analogous to the problem of wellhead protection), and (ii) as an educational tool, to allow users to visualise flow patterns near surface water bodies.
• MODOFC is computer software for optimal groundwater management. MODOFC integrates optimization algorithms with MODFLOW.
• Processing MODFLOW for Windows 4.1 In my personal opinion, there is no better free MODFLOW preprocessor available at present (09 Nov 99)

  SEQUENCE: A unique visualization tool that may be used to clearly demonstrate lines of evidence supporting natural attenuation of petroleum hydrocarbons and chlorinated solvents.  SEQUENCE is ideal for evaluating geochemical indicators of biological degradation and trends in concentrations of organic pollutants.

• Pollution Research Group's MINTEQA2 Home Page. MINTEQA2 can be used to calculate the equilibrium composition of dilute aqueous systems in the aqueous, solid, adsorbed and gaseous phases.
• ANTS Project. "The goals of this project are to develop an ANalytical contaminant Transport Solution library with some model selection guidances, ANTS. Ideally, a guidance will guide a user to select the most appropriate analytical contaminant transport model to predict the outcome of a contaminant transport problem."
• RT3D (version 2.5) is now available at a Battelle-Pacific Northwest National Laboratory web site. A draft version of RT3D reference/ tutorial guide (in ADOBE PDF format) is also available at the web site. RT3D is a multi-species transport model developed from DoD_1.5 (1997) version of the public domain code MT3D. RT3D can be used for modeling any type of subsurface reactions including biological reactions.
• You can download a working demo of Micro-Fem. Micro-Fem is a set of several programs which takes you through the whole process of groundwater modeling, from the generation of a mesh through the stages of preprocessing, calculation, postprocessing, graphical interpretation and plotting. A free version of Micro-Fem has become available that can handle one and two-aquifer systems with up to 2500 nodes per layer. All other features of the professional version are retained. The new zip-file, MICRO-FEM 3.1 LT (light version) comprises all Micro-Fem programs, including FemPath (particle tracking) and FemInvs (inverse modeling).
• BUGS™ SCRATCHPAD, a computer program designed to model many of the subsurface processes in a two-dimensional saturated aquifer, including: advection and dispersion, sorption and desorption, biotic and abiotic chemical reactions and equilibrium conditions.
• Wen-Hsing Chiang has source code for MODFLOW and a functional demo of Processing MODFLOW for Windows. There is also a free beta version of the 2D-FD flow and transport model Aquifer Simulation Model for Windows (ASMWIN) and a program BIN2ASC.EXE for converting the unformatted files MODFLOW output files to ASCII.
• Stream v2.0 is a Fortran source code for mapping dividing stream surfaces in 3D steady velocity fields.
• Environmental/Hydrologic/Hydraulic/Water Resources computer models mirrored in the Civil & Environmental Engineering Department, ODU.
• A few of the programs from International Association for Mathematical Geology may be hydrology related.

• VARIOWIN: Windows™ Software for Exploratory Variography & Variogram Modeling in 2D. Other geostatistical programs can also be downloaded. (Strictly speaking this is not a hydrology program but it may be of interest.)
• Numerical Software Development Describes a project to create "user-friendly and efficient numerical software". Some codes can be downloaded. They are not specifically groundwater related but they may be of interest to developers of groundwater modeling programs.

The following sites have source code or executables but it may be impossible to connect to these sites using Netscape or Mosaic. Instead you may have to use an ftp program such as WS_FTP to link to them. Some contain files that are compressed as TAR.Z or TAR.GZ files. They can be decompressed with WinZip. I recieved a message from R. Steven Regan at the USGS stating that these sites would be discontinued or restricted to internal USGS use. The files in these sites are experimental versions that have not been approved by the USGS.
