Thickness of Aquifer given Drawdown Value measured at Well Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Thickness of Aquifer - (Measured in Meter) - The Thickness of Aquifer vertical thickness of the hydro geologically defined aquifer in which the pore spaces of the rock forming the aquifer are filled with water.
Total Drawdown - (Measured in Meter) - The Total Drawdown 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 is the depth in the well measured above the impermeable layer.

STEP 1: Convert Input(s) to Base Unit

Total Drawdown: 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

(Calculation completed in 00.004 seconds)

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.
