Aquifer Thickness - (Measured in Meter) - The Aquifer Thickness is referred as vertical distance between the top and bottom boundaries of an aquifer, typically measured in feet or meters.

STEP 1: Convert Input(s) to Base Unit

Discharge per Unit Width of Aquifer: 30 Cubic Meter per Second --> 30 Cubic Meter per Second No Conversion Required
Length between Upstream and Downstream: 4.09 Meter --> 4.09 Meter No Conversion Required
Piezometric Head at Upstream End: 12 Meter --> 12 Meter No Conversion Required
Piezometric Head at Downstream End: 5 Meter --> 5 Meter No Conversion Required
Aquifer Thickness: 35 Meter --> 35 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

k = q*L_stream/((h_o-h₁)*b) --> 30*4.09/((12-5)*35)

Evaluating ... ...

k = 0.500816326530612

STEP 3: Convert Result to Output's Unit

0.500816326530612 Meter per Second --> No Conversion Required

FINAL ANSWER

0.500816326530612 ≈ 0.500816 Meter per Second <-- Coefficient of Permeability
