Pumping decision-support calculator
Translate model-choice sensitivity into qualitative uncertainty for allowable pumping and recovery criteria.
Test whether lag-aware aquifer-test interpretation changes an engineering decision variable.
The Decision Lab provides screening tools for Lagging Darcy Law and transformation uncertainty. The first tool is qualitative by design. It identifies when alternative interpretations warrant evaluation; it does not provide a site-specific design value.
Screening tool
Lagging Darcy Law Necessity Checker
This screening tool asks whether a conventional pumping-test interpretation is likely sufficient, or whether a lag-aware interpretation should be evaluated before the result is used in a decision.
Lag-aware interpretation should be considered diagnostic
- Decision variable most exposed
- Parameter transfer and recovery interpretation
- Evidence to check next
- Compare early-time residuals, recovery shape, and boundary assumptions against a lag-aware analytical model.
- Engineer-facing interpretation
- The lag or drainage time scale is not negligible relative to the test window, so conventional interpretation may be adequate for a first fit but should not be the only basis for a decision variable.
This is a transparent qualitative screening tool, not a site-specific engineering analysis. Field decisions still require calibrated data review, uncertainty propagation, and professional judgment.
Tool roadmap
Planned tools will examine model-to-decision consequences.
These public screening and teaching tools will complement, not replace, calibrated field analysis.
