Thickness of Aquifer given Drawdown Value measured at Well Solution

STEP 0: Pre-Calculation Summary

Formula Used

Thickness of Aquifer 1 = Total Drawdown in Well+Depth of Water
b = s_t+h_w
This formula uses 3 Variables

Variables Used

Thickness of Aquifer 1 - (Measured in Meter) - The Thickness of Aquifer 1 vertical thickness of the hydrogeologically defined aquifer in which the pore spaces of the rock forming the aquifer are filled (saturated) with water.
Total Drawdown in Well - (Measured in Meter) - The Total Drawdown in Well is defined as the reduction in hydraulic head observed at a well in an aquifer, typically due to pumping a well as part of an aquifer test or well test.
Depth of Water - (Measured in Meter) - Depth of Water in the well measured above the impermeable layer.

STEP 1: Convert Input(s) to Base Unit

Total Drawdown in Well: 0.83 Meter --> 0.83 Meter No Conversion Required
Depth of Water: 2.44 Meter --> 2.44 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

b = s_t+h_w --> 0.83+2.44

Evaluating ... ...

b = 3.27

STEP 3: Convert Result to Output's Unit

3.27 Meter --> No Conversion Required

FINAL ANSWER

3.27 Meter <-- Thickness of Aquifer 1

Thickness of Aquifer given Discharge in Unconfined Aquifer

Go Thickness of Unconfined Aquifer = sqrt(Depth of Water^2+(Discharge*log((Radius of Influence/Radius of well),e))/(pi*Coefficient of Permeability in Well Hydraulics))

Length of Strainer given Discharge

Go Strainer Length = ((Discharge*log((Radius of Influence/Radius of well),10))/(2.72*Coefficient of Permeability in Well Hydraulics*Total Drawdown in Well in Well Hydraulics))-(Total Drawdown in Well in Well Hydraulics/2)

Thickness of Aquifer for Discharge in Unconfined Aquifer with Base 10

Go Thickness of Aquifer 1 = sqrt(Depth of Water^2+(Discharge*log((Radius of Influence/Radius of well),10))/(1.36*Standard Coefficient of Permeability at 20°C))

Cross-section Area of Soil Mass given Flow Velocity

Go Area of Cross Section in Enviro. Engin. = (Rate of Flow in Aquifer/Flow Velocity for Unconfined Aquifer)

Thickness of Aquifer given Drawdown Value measured at Well

Go Thickness of Aquifer 1 = Total Drawdown in Well+Depth of Water

Thickness of Aquifer given Drawdown Value measured at Well Formula

Thickness of Aquifer 1 = Total Drawdown in Well+Depth of Water
b = s_t+h_w

What is Drawdown?

A drawdown is a peak-to-trough decline during a specific period for an investment, trading account, or fund. A drawdown is usually quoted as the percentage between the peak and the subsequent trough.
