Select either the Professional or Standard version of AQTESOLV for Windows to meet the requirements of your aquifer test analyses.
- The Standard (STD) version provides a set of pumping test and slug test solutions comparable to other commercially available software packages.
- The Professional (PRO) version offers the most complete set of aquifer test solutions. Choose the Professional version for access to sophisticated solutions and features not found in other commercially available software packages. In addition to the advanced solutions (below), the Professional version also includes Derivative Analysis and Diagnostic Flowplots (neither of these are in the standard).

| Single-Well Solutions |
|
AQTESOLV includes many solutions for use in the analysis of single-well aquifer tests.
- The Theis (1935) and Hantush-Jacob (1955) step-drawdown test solutions include linear and nonlinear well losses and allows you to compute well efficiency.
- The Papadopulos-Cooper (1967), Dougherty-Babu (1984), Moench (1997), Moench (1985), Moench (1984) and Barker (1988) solutions include wellbore storage effects for pumping tests performed in confined, unconfined, leaky and fractured aquifers.
- The solutions for slug tests apply to the analysis of single-well underdamped and overdamped slug test in unconfined and confined aquifers.
- The solutions for constant-head tests apply to single-well configurations. Choose from solutions for confined, leaky and fractured aquifers.

|
| Slug Tests with Intertial Effects (Oscillatory Response) |
AQTESOLV includes solutions by Butler (1998), Springer-Gelhar (1991) and Butler-Zhan (2004) for the analysis of slug tests with oscillatory response due to inertial effects. These solutions allow you to analyze data with underdamped and overdamped response and include a correction for frictional well loss in small-diameter wells.

|
| Confined Two-Aquifer Systems |
|
AQTESOLV for Windows includes a sophisticated solution by Neuman and Witherspoon (1969) for the analysis of a confined two-aquifer system with leakage. Unlike the Hantush-Jacob (1955) and Hantush (1960) solutions for leaky aquifers, the Neuman-Witherspoon (1969) solution accounts for drawdown in the unpumped aquifer. |
|
| Single Fracture Solutions |
|
AQTESOLV provides three methods for analyzing fractured aquifers with single fractures. For pumping tests, the Gringarten-Witherspoon (1972) solution accounts for a single vertical plan fracture in an anisotropic fractured medium (uniform flux and infinite conductivity); the Gringarten-Ramey (1974) solution predicts drawdown in an anisotropic fractured aquifer with a single horizontal plane fracture. For constant-head tests, the Ozkan-Raghavan (1991) method simulates a single vertical plan fracture. |
|
| Flow to an Interceptor Trench |
|
AQTESOLV for Windows includes the Murdoch (1994) solution for the analysis of flow to an interceptor trench. Perform aquifer tests with remedial trenches! |
|
| Large-Diameter Well Solutions |
|
The Papadopulos-Cooper (1967), Dougherty-Babu (1984), Moench (1997), Moench (1985), Moench (1984) and Barker (1988) solutions include wellbore storage effects for pumping tests performed in confined, unconfined, leaky and fractured aquifers. Wellbore storage is an important, often overlooked, factor in single-well tests. |

|
| Step Test Analysis |
The Theis (1935) and Hantush-Jacob (1955) step-drawdown test solutions include linear and nonlinear well losses and allows you to compute well efficiency.
All of the pumping tests solutions in AQTESOLV include variable-rate analysis. With this feature, you can use any of the pumping test solutions in the program to simulate stepped variations in pumping (including recovery). |

|
| Variable-Rate and Recovery Test Analysis |
All of the pumping tests solutions in AQTESOLV include variable-rate analysis. With this feature, you can use any of the type curve solutions in the program to simulate recovery as well as drawdown during a pumping test.
AQTESOLV now includes the Agarwal method for analyzing data from a recovery test! |

To design an aquifer test using AQTESOLV for Windows, use the convenient Forward Solution Data Set Wizard to enter data for the pumping and observation wells, choose any solution method, enter estimates of aquifer properties, and plot a type curve to predict drawdown. |
|
| Constant-Head Tests |
|
AQTESOLV provides a suite of solutions for analyzing data from constant-head test in confined, leaky and fractured aquifers. |
|
| Horizontal Wells |
|
AQTESOLV includes a solution by Daviau et al. (1985) for a horizontal well in a confined aquifer. Simulate flow to the well with uniform-flux and infinite-conductivity models. |
|
| Water-Table Aquitard |
|
AQTESOLV now includes a solution by Cooley and Case (1973) for a leaky confined aquifer overlain by a water-table aquitard. |
|
| Confined/Unconfined Conversion |
|
AQTESOLV includes a solution by Moench and Prickett (1972) for a confined aquifer undergoing conversion to unconfined conditions. |

For the double-porosity case, AQTESOLV includes options for slab and spherical matrix blocks. |
|
| Delayed Observation Well Response |
|
AQTESOLV now includes a technique for delayed observation well response (Kipp and Black 1977; Moench 1997) for pumping tests in confined, unconfined and fractured aquifers and slug tests in confined aquifers. |
