Water-well performance
Calculate drawdown and specific capacity, and compare a compatible baseline.
Inputs are sent to the server for this calculation without being saved or added to the URL. Saving a scenario stores it only in this browser.
Formula and assumptions
Enter depths below the same measuring point. Compare only tests with compatible flow, duration and aquifer conditions. Specific capacity depends on the test; it does not establish sustainable yield, aquifer transmissivity or a maintenance diagnosis.
s = pumpingLevel − staticLevel; SC = Q / s; change = 100 × (SC / SC₀ − 1)Method references
