Software

AQTESOLV for Windows

Software for the design and evaluation of pumping tests and slug tests. Features visual and automatic matching, variable pumping rates, multiple pumping wells and observation wells, derivative analysis, and wizards for data entry and data loggers. Free demo available from web site.

The Geotechnical and Geo-Environmental Software Directory

Details several hundred programs, software publishers and suppliers in the fields of Hydrogeology, Geo-environmental Engineering, Geotechnical Engineering, Engineering Geology, Data Analysis and Data Visualization. It also links to other WWW pages with related software.

GFLOW2000 for Windows

Analytical element modeling of groundwater flow and particle tracking. Versatile windows based modeling environment.

MT3D Resources

The Hydrogeology Group at University of Alabama's web page has information, updates and links to MT3D related sites.

PEST: Parameter Estimation with any model

PEST is a nonlinear parameter estimation "shell" that communicates with any existing model through the model's own input and output files. It can calibrate models with up to four unknown parameters. There are utilities to link PEST with MODFLOW and MT3D.

RT3D Bioremediation Code

Three-dimensional transport code used for modeling active bioremediation and natural attenuation problems.

TWODAN and SOLUTRANS from Fitts GeoSolutions

TWODAN for windows is a quick and simple 2-D analytic element model with powerful features like stratified aquifers, heterogeneities, thin barriers (e.g. slurry walls). Ideal for simulating remediation designs, capture zones, and regional flow. Great windows interface, with access to all data in spreadsheet-like grids. SOLUTRANS models 3D solute transport (equilibrium and non-equilibrium) using analytic solutions.
