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

STEP 0: Pre-Calculation Summary

Formula Used

Depth of Water in Well given Drawdown = Thickness of Unconfined Aquifer-Total Drawdown
h_d' = H-s_t
This formula uses 3 Variables

Variables Used

Depth of Water in Well given Drawdown - (Measured in Meter) - Depth of Water in Well given Drawdown is the depth or water level inside a well that can sustain a specific drawdown.
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 - (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.

STEP 1: Convert Input(s) to Base Unit

Thickness of Unconfined Aquifer: 5 Meter --> 5 Meter No Conversion Required
Total Drawdown: 0.83 Meter --> 0.83 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h_d' = H-s_t --> 5-0.83

Evaluating ... ...

h_d' = 4.17

STEP 3: Convert Result to Output's Unit

4.17 Meter --> No Conversion Required

FINAL ANSWER

4.17 Meter <-- Depth of Water in Well given Drawdown

(Calculation completed in 00.020 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.
