AQTESOLV for Windows features visual and automatic methods for matching pumping test and slug test solutions to aquifer test data.  No other program provides greater ease or flexibility in evaluating aquifer test data.

Visual Matching

Just point, click and drag to match a type curve or line to your data.  AQTESOLV for Windows automatically updates hydraulic parameter values as you move the curve!

Match solutions in the traditional way!
Select any curve from type curve family solutions!
No repetitive clicking of cumbersome arrow keys or buttons!

Automatic Matching

Match any aquifer test solution objectively and efficiently using automatic curve matching.   AQTESOLV for Windows uses nonlinear weighted least-squares to determine the optimal match between an aquifer test solution and your data.

Save time and increase precision when matching complex solutions with multiple type curve families!
Apply weights to activate or deactivate measurements during estimation!

Type Curve Families

Click to enlarge image!AQTESOLV for Windows lets you match any curve from solutions with type curve families.  Plus, while matching your data to a specific curve, you can view a family of type curves as a reference for selected solutions.

Choose from three options for displaying type curve families!
Display custom or preset type curve families!
Superimpose the Theis solution on type curve families!

Statistical Analysis

Click image to enlarge!When you perform automatic curve matching, AQTESOLV for Windows also provides a statistical analysis of the curve fitting results.

Residual statistics and residual plots help you analyze the errors between the observed displacement data and an aquifer test solution.
Standard errors allow you to construct approximate confidence intervals for each hydraulic parameter (e.g., T or S) in an aquifer test solution.
