STEP 0: Pre-Calculation Summary
Formula Used
Initial constant Piezometric Head = Possible Drawdown in Confined Aquifer+Drawdown at time t
H = s'+h
This formula uses 3 Variables
Variables Used
Initial constant Piezometric Head - (Measured in Meter) - Initial constant piezometric head is a specific measurement of liquid pressure above a vertical datum.
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 at time t - (Measured in Meter) - Drawdown at time t refers to the lowering of the surface elevation of a body of water, the water table, the piezometric surface, or the water surface of a well, as a result of the withdrawal of water.
STEP 1: Convert Input(s) to Base Unit
Possible Drawdown in Confined Aquifer: 0.2 Meter --> 0.2 Meter No Conversion Required
Drawdown at time t: 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
STEP 3: Convert Result to Output's Unit
10 Meter --> No Conversion Required
FINAL ANSWER
10 Meter <-- Initial constant Piezometric Head

Equation for Drawdown
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'
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'
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 Well Function series to number of 4 digits
Go Well Function of u = -0.577216-ln(Well Parameter)+Well Parameter-(Well Parameter^2/2.2!)+(Well Parameter^3/3.3!)
Equation for Well Parameter
Go Well Parameter = (Distance from Pumping Well^2*Storage Coefficient)/(4*Transmissivity*Time Period)
Distance from Pumping Well given Storage Coefficient
Go Distance from Pumping Well = sqrt((2.25*Transmissivity*Starting Time/Storage Coefficient))
Initial Time given Pumping Well along with Storage Coefficient
Go Starting Time = (Storage Coefficient*Distance from Pumping Well^2)/(2.25*Transmissivity)
Transmissivity about given storage coefficient
Go Transmissivity = (Storage Coefficient*Distance from Pumping Well^2)/(2.25*Starting Time)
Equation for Storage Coefficient
Go Storage Coefficient = 2.25*Transmissivity*Starting Time/Distance from Pumping Well^2
Initial Constant Piezometric Head given drawdown
Go Initial constant Piezometric Head = Possible Drawdown in Confined Aquifer+Drawdown at time t
Drawdown given Piezometric Head
Go Possible Drawdown in Confined Aquifer = Initial constant Piezometric Head-Drawdown at time t

What is Discharge In Hydrology?

Discharge is the volumetric flow rate of water that is transported through a given cross-sectional area. It includes any suspended solids, dissolved chemicals, or biologic material in addition to the water itself.
