Aquifer StepMaster

What is Aquifer StepMaster?

Everyone conducts survey tests, but few people know how to analyze the data. Step-by-step survey testing requires the use of complex graphical techniques that are not widely taught. StepMaster uses graphical analysis methods to analyze step-by-step testing quickly and reliably. No other programs have been developed specifically for Step-Drawdown, such as StepMaster.

Graph test analysis methods

• Eden-Haze (drawdown and recovery to estimate linear coefficients of aquifer transmissibility well loss)
• Birsoy-Summers (survey and recovery analysis to estimate aquifer transmissivity and stun)
• Hantush-Bierschenk (to estimate linear and nonlinear well loss coefficients)

StepMaster Features

• Accepts up to twelve pumping fees (no rates need to increase consecutively or have the same duration)
• Special value tables delimited by H recording tabs and adjusted time of Eden- Hazel-Birsoy-Summers. This allows for additional independent analysis.
• All calculations are displayed in mobile and customizable text boxes.
• Arithmetic, semi-log, and log-log charts
• Broad ability to eliminate unwanted data or entire analysis steps

Resources

• Easy-to-use Windows interface with context-sensitive online help
• Drag-and-drop curve matching
• Wide ability to delete data with on-screen buttons
• Importing data recorder files from most manufacturers without prior editing
• Extensive resistance to program failures due to unusual data sets
• Automatic adjustment of slug test data for maximum displacement in time = 0
• Displaying calculations in mobile, customizable text boxes
• Instant display of the type curve
• Copy charts to clipboard or save as bitmap

System Requirements

Run windows 2000 through 64-bit Windows 7 up to Windows 8/10
