Initial Constant Piezometric Head given Drawdown Solution

STEP 0: Pre-Calculation Summary

Formula Used

Initial Constant Piezometric Head = Possible Drawdown in Confined Aquifer+Drawdown
H = s'+h
This formula uses 3 Variables

Variables Used

Initial Constant Piezometric Head - (Measured in Meter) - Initial Constant Piezometric Head is the initial pressure head in a groundwater system at a specific point before any external influences or changes occur.
Possible Drawdown in Confined Aquifer - (Measured in Meter) - Possible Drawdown in Confined Aquifer is the drawdown that would have occurred if the aquifer had been confined (that is, if no dewatering had occurred).
Drawdown - (Measured in Meter) - Drawdown is the difference in height between the natural water table (or potentiometric surface) and the water level in a well after groundwater has been extracted.

STEP 1: Convert Input(s) to Base Unit

Possible Drawdown in Confined Aquifer: 0.2 Meter --> 0.2 Meter No Conversion Required
Drawdown: 9.8 Meter --> 9.8 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

H = s'+h --> 0.2+9.8

Evaluating ... ...

H = 10

Drawdown

LaTeX Go Total Drawdown = (Discharge/(4*pi*Transmissivity))*ln((2.2*Transmissivity*Time Period)/(Distance from Pumping Well^2*Storage Coefficient))

Drawdown at Time Interval 't1'

LaTeX Go Drawdown at Time Interval t1 = Drawdown at Time Interval t2-((Discharge/(4*pi*Transmissivity))*ln(Time of Drawdown (t2)/Time of Drawdown (t1)))

Drawdown at Time Interval 't2'

LaTeX Go Drawdown at Time Interval t2 = ((Discharge/(4*pi*Transmissivity))*ln(Time of Drawdown (t2)/Time of Drawdown (t1)))+Drawdown at Time Interval t1

Equation for Storage Coefficient

LaTeX Go Storage Coefficient = 2.25*Transmissivity*Starting Time/Distance from Pumping Well^2
