Aquifer Loss given Drawdown Solution

STEP 0: Pre-Calculation Summary

Formula Used

Aquifer Loss = Total Drawdown-Head Loss in Well
BQ = s_t-CQⁿ
This formula uses 3 Variables

Variables Used

Aquifer Loss - (Measured in Meter) - The Aquifer Loss refers to the reduction in the volume of water stored in an aquifer.
Total Drawdown - (Measured in Meter) - The Total Drawdown in Well refers to the reduction in water level from the original, static level to the level during pumping.
Head Loss in Well - (Measured in Meter) - The Head Loss in Well refers to the difference between the head of the aquifer immediately outside and in the well a head inside because of all these losses.

STEP 1: Convert Input(s) to Base Unit

Total Drawdown: 28 Meter --> 28 Meter No Conversion Required
Head Loss in Well: 0.52 Meter --> 0.52 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

BQ = s_t-CQⁿ --> 28-0.52

Evaluating ... ...

BQ = 27.48

STEP 3: Convert Result to Output's Unit

27.48 Meter --> No Conversion Required

FINAL ANSWER

27.48 Meter <-- Aquifer Loss

(Calculation completed in 00.004 seconds)

What is Well Loss?

When water is pumped out of a well, the total drawdown caused includes not only that of the logarithmic drawdown curve at the well face, but also drawdown caused by flow through well screen and axial movement within the well. The latter drawdown is called well loss.

How to Calculate Aquifer Loss given Drawdown?

Aquifer Loss given Drawdown calculator uses Aquifer Loss = Total Drawdown-Head Loss in Well to calculate the Aquifer Loss, The Aquifer Loss given Drawdown formula is defined as a measure of the reduction in artesian pressure head in an aquifer due to the pumping of groundwater from a well, which affects the well's productivity and the surrounding groundwater flow. Aquifer Loss is denoted by BQ symbol.

How to calculate Aquifer Loss given Drawdown using this online calculator? To use this online calculator for Aquifer Loss given Drawdown, enter Total Drawdown (s_t) & Head Loss in Well (CQⁿ) and hit the calculate button. Here is how the Aquifer Loss given Drawdown calculation can be explained with given input values -> 27.48 = 28-0.52.

FAQ

What is Aquifer Loss given Drawdown?

The Aquifer Loss given Drawdown formula is defined as a measure of the reduction in artesian pressure head in an aquifer due to the pumping of groundwater from a well, which affects the well's productivity and the surrounding groundwater flow and is represented as BQ = s_t-CQⁿ or Aquifer Loss = Total Drawdown-Head Loss in Well. The Total Drawdown in Well refers to the reduction in water level from the original, static level to the level during pumping & The Head Loss in Well refers to the difference between the head of the aquifer immediately outside and in the well a head inside because of all these losses.

How to calculate Aquifer Loss given Drawdown?
