sci.well-pumping-theis Calculator
Calculates aquifer transmissivity and storativity from pumping test drawdown data using the Theis non-equilibrium method. The Theis equation assumes a confined aquifer with infinite extent — type-curve matching determines aquifer hydraulic properties from a single pumping test.
Inputs
Pumping Rate M3 S
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Transmissivity M2 S
Reference formula or conversion factor shown for context.
Storativity
Reference formula or conversion factor shown for context.
Radial Distance M
Separation between two points or total path length. Check that units are consistent throughout the calculation.
Time Hours
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Results
drawdown s (m)
Sample size or count used in the calculation.
well function W(u)
The type of mathematical function or operational classification determined by the calculation.
dimensionless parameter u
Sample size or count used in the calculation.
s = Q/(4πT) × W(u)
Reference formula or conversion factor shown for context.
