How to use the aquifer transmissivity calculator
Find how easily water flows through the full thickness of an aquifer from its conductivity and thickness. Enter hydraulic conductivity, aquifer thickness in the fields above; the transmissivity are computed instantly and plotted on the chart so you can see how the answer changes.
Common searches this calculator answers include “aquifer transmissivity”, “transmissivity of groundwater”, “hydraulic conductivity times thickness”, “calculate aquifer transmissivity”, “find transmissivity”.
Formula
Variables
- K — Hydraulic conductivity (m/s)
- b — Aquifer thickness (m)
Worked example
With hydraulic conductivity = 0.0001 m/s, aquifer thickness = 30 m, the calculator gives transmissivity ≈ 0.003 m²/s; transmissivity ≈ 259.2 m²/day.
Frequently asked questions
What is the aquifer transmissivity calculator used for?
Find how easily water flows through the full thickness of an aquifer from its conductivity and thickness. It helps with questions such as “aquifer transmissivity”, “transmissivity of groundwater”, “hydraulic conductivity times thickness”.
What is the formula for the aquifer transmissivity calculation?
Transmissivity (m²/s) = K × b. Transmissivity (m²/day) = [Transmissivity] × 86400. Here K is hydraulic conductivity (m/s), b is aquifer thickness (m).
What inputs do I need for the aquifer transmissivity calculator?
You need hydraulic conductivity in m/s, aquifer thickness in m. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the aquifer transmissivity calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the aquifer transmissivity result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
