Advanced Solutions | List of Solutions

AQTESOLV constant-head test (constant-drawdown test) software features the most comprehensive suite of analytical solutions for evaluating constant-head tests (constant-drawdown tests) in confined, leaky and fractured aquifers.

Advanced Solutions for Constant-Head Test (Constant-Drawdown Test) Analysis

AQTESOLV/Professional contains many constant-head test (constant-drawdown test) solutions not available in competing software packages:

• solutions for confined, leaky and fractured aquifers
• recovery tests

Solutions for Confined, Leaky and Fractured Aquifers

AQTESOLV includes solutions for confined, leaky and fractured aquifers. Options include recovery, wellbore skin, vertical fractures and the generalized radial flow model of Barker (1988).

Recovery Tests

AQTESOLV lets you analyze not only the constant-head phase of a test, but the recovery phase as well.
