Wells & water/ CALCULATOR
Well drawdown & specific capacity
Interpret water levels from a recorded pumping test.
Measured below a fixed datum before pumping.
Use the same datum and record the test duration.
Stable measured flow at the stated test conditions.
Observed drawdown
6.00 m
Specific capacity
3.33 L/min/m
A snapshot of a test, not a sustainable-yield guarantee. Requires pumping depth greater than static depth. A well professional must interpret test duration, recovery and seasonal effects.
