This formula uses 6 Variables
Variables Used
Radius of Well given Discharge - (Measured in Meter) - Radius of Well given Discharge is the radial distance from the center of the well to the outer boundary of the aquifer, where the effects of pumping or water withdrawal are observed.
Radius of Influence - (Measured in Meter) - Radius of Influence measured from the center of the well to the point where drawdown curve meets the original water table.
Coefficient of Permeability of Soil Particle - (Measured in Meter per Second) - Coefficient of Permeability of Soil Particle describes how easily a liquid will move through the soil.
Initial Aquifer Thickness - (Measured in Meter) - Initial Aquifer Thickness is the aquifer thickness at initial stage before pumping.
Depth of Water - (Measured in Meter) - Depth of Water is the depth in the well measured above the impermeable layer.
Discharge - (Measured in Cubic Meter per Second) - Discharge is the flow rate of water that is extracted from or injected into a well.
STEP 1: Convert Input(s) to Base Unit
Radius of Influence: 8.6 Meter --> 8.6 Meter No Conversion Required
Coefficient of Permeability of Soil Particle: 0.001 Centimeter per Second --> 1E-05 Meter per Second (Check conversion ​here)
Initial Aquifer Thickness: 2.48 Meter --> 2.48 Meter No Conversion Required
Depth of Water: 2.44 Meter --> 2.44 Meter No Conversion Required
Discharge: 1.01 Cubic Meter per Second --> 1.01 Cubic Meter per Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
rw = Rw/10^((1.36*Ksoil*(Hi^2-hw^2))/Q) --> 8.6/10^((1.36*1E-05*(2.48^2-2.44^2))/1.01)
Evaluating ... ...
rw = 8.59994752463795
STEP 3: Convert Result to Output's Unit
8.59994752463795 Meter --> No Conversion Required
FINAL ANSWER
8.59994752463795 8.599948 Meter <-- Radius of Well given Discharge

What is Unconfined Aquifer?

Unconfined aquifers are those into which water seeps from the ground surface directly above the aquifer. Confined aquifers are those in which an impermeable dirt/rock layer exists that prevents water from seeping into the aquifer from the ground surface located directly above.
