Drawdown in aquifer for total drawdown Solution

STEP 0: Pre-Calculation Summary

Formula Used

Change in Drawdown = Total Drawdown-Well loss
s = s_t-CQⁿ
This formula uses 3 Variables

Variables Used

Change in Drawdown - (Measured in Meter) - Change in Drawdown in the Aquifer is a term applied to the maximum lowering of the groundwater table caused by pumping or artesian flow.
Total Drawdown - (Measured in Meter) - Total Drawdown is 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.
Well loss - (Measured in Meter) - Well loss is defined as the head loss in well.

STEP 1: Convert Input(s) to Base Unit

Total Drawdown: 5.1 Meter --> 5.1 Meter No Conversion Required
Well loss: 5 Meter --> 5 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

s = s_t-CQⁿ --> 5.1-5

Evaluating ... ...

s = 0.0999999999999996

STEP 3: Convert Result to Output's Unit

0.0999999999999996 Meter --> No Conversion Required

FINAL ANSWER

0.0999999999999996 ≈ 0.1 Meter <-- Change in Drawdown

What is Water Well Drawdown?

Drawdown is a change in groundwater level due to an applied stress, caused by events such as: Pumping from a well. Pumping from a neighboring well. Intensive water taking from local area. Seasonal declines as recharge rates lower

What is an aquifer?

An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials. Groundwater from aquifers can be extracted using a water well. The study of water flow in aquifers and the characterization of aquifers is called hydrogeology.
