Pumping decision reliability calculator
Translate model-choice sensitivity into qualitative exposure for allowable pumping and recovery criteria.
Test whether memory-aware interpretation matters before it enters a decision.
The Decision Lab turns Lagging Darcy Law and transformation uncertainty into screening workflows. The first tool is qualitative by design: it flags when evidence should be checked, not what a site-specific design value should be.
Screening tool
Lagging Darcy Law Necessity Checker
This screening tool asks whether a conventional pumping-test interpretation is likely sufficient, or whether a memory-aware interpretation should be checked before the result is used in a decision.
Memory-aware review recommended 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 memory-aware alternative.
- Engineer-facing interpretation
- The memory 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 endpoint.
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
Next tools should expose model-to-decision consequences.
These are planned as public screening and teaching tools, not substitutes for calibrated field analysis.
