Depth of Water in Well given Drawdown Value measured at Well Solution

STEP 0: Pre-Calculation Summary
Formula Used
Depth of Water = Thickness of Unconfined Aquifer-Total Drawdown in Well
hw = H-st
This formula uses 3 Variables
Variables Used
Depth of Water - (Measured in Meter) - Depth of Water in the well measured above the impermeable layer.
Thickness of Unconfined Aquifer - (Measured in Meter) - Thickness of Unconfined Aquifer is measured from impermeable layer to the initial level of water table.
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.
STEP 1: Convert Input(s) to Base Unit
Thickness of Unconfined Aquifer: 5 Meter --> 5 Meter No Conversion Required
Total Drawdown in Well: 0.83 Meter --> 0.83 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
hw = H-st --> 5-0.83
Evaluating ... ...
hw = 4.17
STEP 3: Convert Result to Output's Unit
4.17 Meter --> No Conversion Required
FINAL ANSWER
4.17 Meter <-- Depth of Water
(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.
