Drawdown in Well 1 given Thickness of Aquifer from Impermeable Layer Solution

STEP 0: Pre-Calculation Summary

Formula Used

Drawdown in Well 1 = Thickness of Aquifer-Depth of Water in Well 1
s₁ = H-h₁
This formula uses 3 Variables

Variables Used

Drawdown in Well 1 - (Measured in Meter) - Drawdown in Well 1 refers to the reduction in water level caused by pumping in a well.
Thickness of Aquifer - (Measured in Meter) - Thickness of aquifer refers to the vertical distance between the top and bottom boundaries of the water-bearing layer, typically measured from the confining bed above to the confining bed below.
Depth of Water in Well 1 - (Measured in Meter) - Depth of Water in Well 1 refers to the vertical distance from the ground surface to the water level within a well that taps into a confined aquifer.

STEP 1: Convert Input(s) to Base Unit

Thickness of Aquifer: 20 Meter --> 20 Meter No Conversion Required
Depth of Water in Well 1: 17.85 Meter --> 17.85 Meter No Conversion Required

STEP 2: Evaluate Formula

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.
