FEFLOW ($100 - $300 DISCOUNT)
Finite Element Subsurface Flow System

FEFLOW is the most advanced finite element model available for simulating density-dependent groundwater flow with mass and heat transport. Since the initial development over 10 years ago, FEFLOW has evolved into one of the most powerful modeling software packages available and is now used by leading consultants, government agencies and educational institutions around the world. FEFLOW utilizes a 3-D graphical interface that allows the user to systematically navigate through the modeling process. Even though FEFLOW is well suited for most 2-D and 3-D flow and transport modeling applications, FEFLOW excels in cases that involve complex geological formations, unsaturated flow, density-dependent flow or thermal convection. FEFLOW's combination of a menu-driven interface together with robust numeric solvers and a database/GIS coupled exchange interface, reduce the complications typically associated with modeling complex multi-dimensional hydrogeologic conditions.

SOILVISION ($100 DISCOUNT)
Estimation of Saturated and Unsaturated Soil Property Functions - Soil Water Characteristic Curve

The modeling of unsaturated soil processes such as seepage, contaminant transport, stress, and thermal analysis all require information on unsaturated soil property functions. SoilVision provides you with the benefit of experimental data on over 5,000 soils. The knowledge of experts has also been incorporated to provide interpretation and predictive capabilities to the system. SoilVision offers a level of estimation of soil parameters and unsaturated and saturated soil property functions never before available incorporating an easy-to-use Windows interface, a database of unprecedented detail, and a knowledge-based system. As a result, numerical modeling was never so easy!

AQUASEA ($100 DISCOUNT)
Tidal Flow in Estuaries and Coastal Areas, Lake Circulation,
Transport Modeling

AQUASEA is a software package developed to solve the shallow water flow and transport equations using the Galerkin finite element method. AQUASEA was first developed in 1983 to solve two-dimensional problems, and since 1992, it has been continuously upgraded and tested worldwide on the most difficult modeling problems. The latest development of AQUASEA is a version that runs in Windows95 or Windows NT. It has been specifically configured and compiled to provide maximum efficiency in model set up and fast model run times. The Windows environment provides not only a multi-platform capability but also an assured industry-standard user interface for future developments. The AQUASEA model consists of the following two models: hydrodynamic flow model and transport-dispersion model. The AQUASEA flow model can simulate water level variations and flows in response to various forcing functions in lakes, estuaries, bays and coastal areas. The water levels and flows are approximated in a numerical finite element grid and calculated on the basis of information on the bathymetry, bed resistance coefficients, wind field and boundary conditions.

VISUAL PEST ($100 DISCOUNT)
Graphical Model-Independent Parameter Estimation

Visual PEST combines the powerful parameter estimation capabilities of PEST2000 with the graphical processing and display features of WinPEST. PEST2000 is the latest version of PEST, the pioneer in model-independent parameter estimation. Since it was first released over six years ago, PEST has gained extensive use all over the world in many different fields. Over this time it has undergone continued development with the addition of many new features that have improved its performance and utility to a level that makes it uniquely applicable in just about any modeling environment. PEST is now used  extensively for automated model calibration and data interpretation  in groundwater and surface water hydrology, geophysics, geotechnical, mechanical and mining engineering, as well as many other fields.

GROUNDWATER VISTAS ($50 DISCOUNT)
Graphical User Interface for MODFLOW, MODPATH, MT3D,
RT3D, PEST and UCODE

Groundwater Vistas (GV) offers the best value of any groundwater modeling interface, providing more advanced capabilities at a lower price than any competing product. GV provides full preprocessing and graphical analysis. GV performs many advanced analyses not found in other MODFLOW interfaces including automated calibration, automated sensitivity analysis, Monte Carlo modeling, and telescopic mesh refinement (TMR). GV fully supports both PEST and UCODE for parameter estimation, and there is a built-in inverse model within the GV interface that is very easy to use. The automated sensitivity analysis provides a powerful way of evaluating the importance of any model parameter and can be scripted to test groups of parameters without user intervention. GV provides the only MODFLOW interface with full Monte Carlo capabilities for MODFLOW, MODPATH and MT3D. GV is also the only interface to provide quick and easy telescopic mesh refinement which is ideal for creating local-scale transport models.

CHEMPOINT/CHEMSTAT
CHEMPOINT (NEW VERSION RELEASED)
Complete Environmental Data Management and Reporting
for Air, Soil, Surface Water, Ground Water, Ash, Sludge,
Bio-Tissue

ChemPoint has been recently updated to provide complete data management, importing, exporting, reporting, and well construction diagrams in a single application. New Version 4 features an easy-to-use Microsoft Outlook style interface, drag-and-drop parameter management, and spreadsheet style interface for entering parameter concentrations. ChemPoint also includes powerful import capabilities for ASCII text, dBase, Access, GRITS, Sanitas, Monitor, and DUMPStat. All facility data is stored in a single database file. The all new design solves many of the problems of environmental data management including importing laboratory data, multiple names for the same parameters, unit conversions, and ordering parameters for display. As always, there are no "per-facility" fees.

CHEMSTAT
Windows 95/NT-Based Program for Fast and Accurate
Analysis of Ground-Water Monitoring Data at RCRA Facilities

Analysis methods in ChemStat comply with 1989 and 1992 US EPA statistical guidance documents (included with the program). ChemStat is not a converted DOS program but is written as a 32-bit windows 95/NT program from the first line of code. ChemStat is fast and powerful. The number of samples and number of wells are limited only by available computer memory. ChemStat has been tested on data sets with up to 5,000 samples. ChemStat includes easy-to-use Windows 95 interface features such as context sensitive on-line help, Tip of the Day screen on startup, recent file lists, customizable printing with print-preview, spin buttons for numerical data entry, and more. Parameters and wells for analysis are selected from a drop-down list box on the main window tool bar. ChemStat is not a database, but is designed specifically for statistical analysis of data. Data is imported from tab-delimited ASCII text files. Utilities to convert data from GRITS/STAT and ChemPoint formats are included. Importing accommodates filtering by start and end date, facility ID, and parameter suite. ChemStat also accepts comparison levels such as MCL for each parameter.

SURFER/GRAPHER
SURFER (CONTOURING SOFTWARE) VERSION 7
Surfer is a 3D contouring and surface plotting program that runs under Microsoft Windows. Surfer quickly and easily converts your data into outstanding contour maps and surface plots. And with all the options available in Surfer, you can customize the maps to produce exactly the presentation you want. Producing publication quality maps in Surfer has never been quicker, easier, and more satisfying.

GRAPHER VERSION 2
Grapher for Windows is a technical graphing software package designed for scientists and engineers. Grapher gives you full control over all the graph features to get the exact presentation you want. You can produce line graphs, scatter plots, bar charts, function plots, and hi-low-close graphs, and include any number of graphs and any combination of graph types on a single page.
