Equation of Hydraulic Grade Line in Confined Groundwater Flow Solution

STEP 0: Pre-Calculation Summary

Formula Used

Piezometric Head = Piezometric Head at Upstream End-((Piezometric Head at Upstream End-Piezometric Head at Downstream End)/Length between Upstream and Downstream)*Flow in 'x' Direction
P = h_o-((h_o-h₁)/L_stream)*x
This formula uses 5 Variables

Variables Used

Piezometric Head - (Measured in Meter) - The Piezometric Head refers to the specific measurement of liquid pressure above a vertical datum, typically measured as the elevation of the liquid surface at the entrance of a piezometer.
Piezometric Head at Upstream End - (Measured in Meter) - The Piezometric Head at Upstream End refers to the specific measurement of liquid pressure above a vertical datum.
Piezometric Head at Downstream End - (Measured in Meter) - The Piezometric Head at Downstream End refers to the specific measurement of liquid pressure above a vertical datum.
Length between Upstream and Downstream - (Measured in Meter) - The Length between Upstream and Downstream refers to the horizontal base with a difference in surface elevations.
Flow in 'x' Direction - (Measured in Cubic Meter per Second) - The Flow in 'x' Direction refers to the one-dimensional Dupit flow with recharge representation.

STEP 1: Convert Input(s) to Base Unit

Piezometric Head at Upstream End: 12 Meter --> 12 Meter No Conversion Required
Piezometric Head at Downstream End: 5 Meter --> 5 Meter No Conversion Required
Length between Upstream and Downstream: 4.09 Meter --> 4.09 Meter No Conversion Required
Flow in 'x' Direction: 2 Cubic Meter per Second --> 2 Cubic Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P = h_o-((h_o-h₁)/L_stream)*x --> 12-((12-5)/4.09)*2

Evaluating ... ...

P = 8.57701711491443

STEP 3: Convert Result to Output's Unit

8.57701711491443 Meter --> No Conversion Required

FINAL ANSWER

8.57701711491443 ≈ 8.577017 Meter <-- Piezometric Head

What is Head in Hydrology?

In fluid dynamics, head is a concept that relates the energy in an incompressible fluid to the height of an equivalent static column of that fluid. Velocity head is due to the bulk motion of a fluid (kinetic energy). Its pressure head correspondent is the dynamic pressure.
