Wellfield Simulations

This will be my last post for 2007, so let me begin by expressing my sincere appreciation and gratitude to all of you who have either become new AQTESOLV customers or continued to support the software by upgrading in the past year. As always I'm working hard to add new features that will maintain AQTESOLV's status as the leading software for aquifer test analysis.

As many of you already know, AQTESOLV includes the capability to model more than one pumping well in either pumping test analyses or predictive simulations. You may enter a variable pumping rate schedule for each well. For example, you can use the multiple pumping well feature to predict total drawdown in a wellfield as shown in the contour plot.

Another use of this multi-well feature would be to include the effect of more than one pumping well in the analysis of a pumping test (e.g., a domestic well that turns on and off during your test). Image wells can be simulated in the same way.

Best wishes for a happy and healthy New Year!

NGWA Expo in Orlando

On Thursday, December 6, I swooped into Orlando, FL for a brief visit to the 2007 NGWA Ground Water Expo held at the Orlando County Convention Center. In the afternoon, I gave an invited oral presentation entitled Aquifer Test Analysis: A Modern Approach as part of a special technical session on "Advances in the Water Well Industry Over the Past 20 Years" moderated by Bob Sterrett and John Jansen.

In my talk, I emphasized the important role of specialized computer software such as AQTESOLV in the analysis of aquifer test data. Particular advantages of computer-assisted analysis over traditional methods of interpretation include diagnostic tools (diagnostic flow plots and derivative analysis); choice of curve matching method (visual and automatic); and statistical methods for interpreting results. In addition, the most recently published mathematical solutions are simply not well suited to graphical analysis using type curve techniques due to the large number of type curves required for their application. Consequently, a modern approach to aquifer test analysis takes advantage of the power afforded by today’s specialized software.
