Area of Well given Time Interval Solution

STEP 0: Pre-Calculation Summary
Formula Used
Area of the Well = Proportionality Constant*Time Interval/ln(Drawdown at the Start of Recuperation/Drawdown at a Time)
A = K0*Tr/ln(H1/H2)
This formula uses 1 Functions, 5 Variables
Functions Used
ln - The natural logarithm, also known as the logarithm to the base e, is the inverse function of the natural exponential function., ln(Number)
Variables Used
Area of the Well - (Measured in Square Meter) - The Area of the Well is referred as land area around a well that is influenced by pumping.
Proportionality Constant - The Proportionality Constant is referred as characteristics of the aquifer and the area of the well. It represents discharge per unit drawdown also called specific capacity of well.
Time Interval - (Measured in Second) - The Time Interval refers to a specific duration or period of time used for measuring or analyzing drawdown.
Drawdown at the Start of Recuperation - (Measured in Meter) - The Drawdown at the Start of Recuperation refers to the measurement of the groundwater level immediately after pumping has ceased and natural replenishment (recharge) begins to take effect.
Drawdown at a Time - (Measured in Meter) - The Drawdown at a Time refers to the measurement or calculation of the groundwater level decline over a specific period, usually related to pumping or natural recharge cycles.
STEP 1: Convert Input(s) to Base Unit
Proportionality Constant: 4.285 --> No Conversion Required
Time Interval: 2 Second --> 2 Second No Conversion Required
Drawdown at the Start of Recuperation: 15 Meter --> 15 Meter No Conversion Required
Drawdown at a Time: 10 Meter --> 10 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
A = K0*Tr/ln(H1/H2) --> 4.285*2/ln(15/10)
Evaluating ... ...
A = 21.136220672566
STEP 3: Convert Result to Output's Unit
21.136220672566 Square Meter --> No Conversion Required
FINAL ANSWER
21.136220672566 21.13622 Square Meter <-- Area of the Well

What is Groundwater Recharge?

Groundwater Recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer.
