Software Interface

Software Evalaution Key #1

Find an intuitive and easy-to-use software interface.

Comparison Tips

The software interface is a subjective area in your decision. We encourage you to test competing packages to see how their interfaces compare. You will find that is both intuitive and easy to use.

  • Only features intuitive data input wizards with graphical prompts that ensure complete and accurate data entry.
  • Only has the interactive Solution Expert that helps you find the right solution method for your test analysis.
  • Only includes Quick Tips, an optional feature that prompts you with helpful popup tips for using the software.
  • Only gives you a total of 17 different customizable plots for displaying and analyzing aquifer test data.
  • Context-sensitive help is available throughout the application.
  • also comes with step-by-step tutorials to show you how to use the program. Plus you can access our Knowledge Base and examples on the web.

AQTESOLV Testimonials

"I chose AQTESOLV for its ease of use."
David Preston, P.E., Peachtree Environmental

"I use AQTESOLV in my Hydrology and Water Resources 603 graduate class on well hydraulics and pumping test analysis."
Dr. Shlomo P. Neuman, University of Arizona

"AQTESOLV is a powerful software for aquifer test data analysis."
Dr. Vedat Batu, URS

Working With Data Loggers

Software Evaluation Key #2

Expect flexible tools for importing data logger files.

Comparison Tips

was the first software to introduce an Import Wizard for data logger files way back in 1997. presently imports data from a variety of data loggers. Expect this feature in a package for aquifer test analysis.

  • provides two easy methods for you to work with data logger files:
    -- import files with a versatile Import Wizard
    -- copy and paste data from spreadsheets
  • lets you import date/time formats.
  • includes handy math functions and filters to help you manipulate the data.

AQTESOLV Testimonials

"The wizards are a great addition!"
Rezie Jan, URS Greiner Woodward Clyde

Diagnostic Tools

Software Evaluation Key #3

Select a package with superior diagnostic methods.

Comparison Tips

Diagnostic methods are an essential tool for aquifer test analysis. These tools can help you select an appropriate solution for your test. Choose the software package with the most advanced diagnostic tools.

  • is the only package with diagnostic flow plots for pumping test analysis: radial, linear, bilinear and spherical flow plots.
  • was the first package to include derivative plots in 1997. Only provides you with the flexibility and power of four different methods for computing derivatives.
  • is the only package with an interactive slope checking tool to help you diagnose specific flow conditions.

AQTESOLV Testimonials

"AQTESOLV is the 'industry standard' for the interpretation of aquifer tests."
Dr. Joe Donovan, West Virginia University

Solution Methods

Software Evaluation Key #4

Get a software package with the most comprehensive set of solution methods.

Comparison Tips

Your ability to perform a complete and thorough analysis of an aquifer test depends on your ability to access appropriate solution methods. In this critical area, is the clear leader while competing aquifer test software packages fall short.

  • has the most comprehensive suite of solutions for the analysis of pumping tests, single-well tests, recovery tests, variable-rate tests, step-drawdown tests, slug tests and constant-head tests.
  • Only provides advanced pumping test solutions for conditions such as leaky confined two-aquifer systems, wedge-shaped aquifers, nonuniform aquifers, water-table aquitards, single fractures, horizontal wells, interceptor trenches, step-drawdown tests in leaky aquifers, bounded aquifers including strip aquifers and the generalized radial flow model.
  • Only has advanced features for slug tests including underdamped (oscillatory) tests in partially penetrating wells, wells screened across the water table using the Dagan (1978) method, tests in fractured aquifers and analysis by deconvolution.
  • Only has constant-head test solutions for confined, leaky and fractured aquifers including recovery.

AQTESOLV Testimonials

"I cannot imagine that I ever tried to analyze aquifer tests with manually plotted data curves using a light table. What a tremendous service you have provided with this software. Thank you."
Jim Borchers, USGS

Curve Matching

Software Evaluation Key #5

Choose software with state-of-the-art curve matching tools.

Comparison Tips

You should expect a software package for aquifer test analysis to provide you with state-of-the-art methods for visual and automatic curve matching. Since its first release, has combined these two fitting techniques.

  • Only provides you with three different methods for curve matching: visual, automatic and parameter tweaking.
  • is the only package to offer active type curves, a powerful interface feature that makes visual curve-matching analysis of variable-rate pumping tests and underdamped slug tests a snap!
  • Only adds the power of singular-value decomposition to enhance automatic curve matching applied to complex problems.

AQTESOLV Testimonials

"The families of curves are terrific and do everything I could possibly ask. Absolutely super!"
William Hotchkiss, Ph.D., NRCE, Inc.

Prediction and Test Design

Software Evaluation Key #6

Look for a software package offering prediction and test design capabilities.

Comparison Tips

Predictive capabilities are invaluable for designing an aquifer test in preparation for field activities. Prediction also lets you forecast the extent of future drawdown for one or more pumping wells.

AQTESOLV Testimonials

"I have been using AQTESOLV since 1989. It has been a great educational tool and I highly recommend it to all groundwater professionals."
Prof. Al Woodbury, University of Manitoba


Software Evaluation Key #7

Select a package with comprehensive output options for not only curve matching but statistical analysis as well.

Comparison Tips

Output should include a complete set of plots and reports to summarize the results of your analysis.

  • Only includes plots and reports for analyzing statistical results of curve matching.
  • provides comprehensive control over fonts, line styles and widths, colors and other formatting elements.
  • Copy and paste plots from into other applications such as Word or Powerpoint.
  • seamlessly links to Surfer, a versatile package for 2-D and 3-D contouring.
  • supports batch printing, a handy feature that allows you to apply consistent formatting to a group of tests.

AQTESOLV Testimonials

"I really like the automatic gridding link to Surfer!"
David Dahlstrom, Barr Engineering

Support and Training

Software Evaluation Key #8

Expect unlimited and free technical support.

Comparison Tips

When comparing software, be sure to try out the Contents and Index of each program's Help file to see if you can quickly find topics of interest. Choose a package with context-sensitive help.
