Aquifer Transmissivity Calculator

Calculate transmissivity T = K·b and storativity S from aquifer tests. Theis type curve matching: T = Q/(4πs)·W(u), S = 4Tu/r². Cooper-Jacob straight-line method for late time data.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.

How It Works

Calculate transmissivity T = K·b and storativity S from aquifer tests. Theis type curve matching: T = Q/(4πs)·W(u), S = 4Tu/r². Cooper-Jacob straight-line method for late time data

Each component has a specific meaning:

  • Aquifer tests — The aquifer tests recorded for the patient or scenario being assessed.

Note: Interpret the aquifer transmissivity result against the clinical thresholds and context described above.

How to Use

Enter the aquifer tests for the patient or scenario you are assessing. Calculate transmissivity T = K·b and storativity S from aquifer tests. Theis type curve matching: T = Q/(4πs)·W(u), S = 4Tu/r². Cooper-Jacob straight-line method for late time data. Use the aquifer transmissivity result to inform your clinical assessment.
