Drawdown in Aquifer given Well Efficiency Solution

STEP 0: Pre-Calculation Summary

Formula Used

Change in Drawdown = Well Efficiency*Drawdown Inside the Well
s = E*s_t
This formula uses 3 Variables

Variables Used

Change in Drawdown - (Measured in Meter) - The Change in Drawdown refers to the term applied to the maximum lowering of the groundwater table caused by pumping or artesian flow.
Well Efficiency - The Well Efficiency refers to the ratio of the drawdown in the aquifer at the radius of the pumping well to the drawdown inside the well.
Drawdown Inside the Well - (Measured in Meter) - The Drawdown Inside the Well refers to the radius of the pumping well is a change in groundwater level due to an applied stress.

STEP 1: Convert Input(s) to Base Unit

Well Efficiency: 1.11 --> No Conversion Required

What is Well Efficiency?

Well efficiency can be defined as the ratio of the drawdown in the aquifer at the radius of the pumping well to the drawdown inside the well .

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
