Pumping Test Analysis

Pumping Test Analysis Tool

This tool supports the interpretation of single-well pumping tests following the ICRC guidelines (2011). It is intended for use by hydrogeologists and field engineers analysing borehole test data.

Supported Test Types

• Constant-rate test — Cooper-Jacob straight-line method
• Recovery test — Theis recovery method
• Step-drawdown test — Hantush-Bierschenk method

How to Use

1. Select the test type from the sidebar.
2. Enter borehole information (name and static water level are required).
3. Upload your CSV data file. The file must contain columns: time_min and level_m.
4. For step-drawdown tests, define the flowrate and end time for each step.
5. Click Run Analysis.
6. Review the data preview to confirm the file loaded correctly.
7. On the Analysis tab, adjust the fit window if needed — aim for R² > 0.95.
8. Review the Results and Interpretation tabs.
9. Download the report from the Export tab.

CSV File Format

Your data file must be a comma-separated CSV with the following columns:

Column	Description
time_min	Elapsed time since start of test [minutes]
level_m	Water level measured from datum [m below datum]
