Aquifer Thickness from Impermeable Layer given Discharge in Confined Aquifer with Base 10 Solution

STEP 0: Pre-Calculation Summary

Formula Used

Initial Aquifer Thickness = Depth of Water+((Discharge*log((Radius of Influence/Radius of Well),10))/(2.72*Coefficient of Permeability*Aquifer Thickness))
H_i = h_w+((Q*log((R_w/r),10))/(2.72*K_w*b_w))
This formula uses 1 Functions, 7 Variables

Functions Used

log - Logarithmic function is an inverse function to exponentiation., log(Base, Number)

Variables Used

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.
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.
Radius of Well - (Measured in Meter) - Radius of Well is defined as the distance from center of well to its outer boundary.
Coefficient of Permeability - (Measured in Meter per Second) - Coefficient of Permeability is the velocity in meters or centimeters per second of water through soils.
Aquifer Thickness - (Measured in Meter) - Aquifer Thickness (at Midpoint between Equipotential lines) or otherwise is the thickness of aquifer in which the pore spaces of rock forming the aquifer may or may not be with water.

STEP 1: Convert Input(s) to Base Unit

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
Radius of Influence: 8.6 Meter --> 8.6 Meter No Conversion Required
Radius of Well: 7.5 Meter --> 7.5 Meter No Conversion Required
Coefficient of Permeability: 1125 Centimeter per Second --> 11.25 Meter per Second (Check conversion here)
Aquifer Thickness: 14.15 Meter --> 14.15 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

H_i = h_w+((Q*log((R_w/r),10))/(2.72*K_w*b_w)) --> 2.44+((1.01*log((8.6/7.5),10))/(2.72*11.25*14.15))

Evaluating ... ...

STEP 3: Convert Result to Output's Unit

2.4792450831839 Meter --> No Conversion Required

FINAL ANSWER

2.4792450831839 ≈ 2.479245 Meter <-- Initial Aquifer Thickness
