How to Calculate and Solve for Seepage Velocity | Hydrology II
Last Updated on April 17, 2024
The image above represents seepage velocity. Two essential parameters are needed to calculate seepage velocity: the rate of unit discharge (q) and the net sectional area of voids (Av).
The formula for calculating seepage velocity:
vs = q / Av
Where:
vs = Seepage Velocity
q = Rate of Unit Discharge
Av = Net Sectional Area of Voids
Let’s solve an example;
Find the seepage velocity when the rate of unit discharge is 10, and the net sectional area of voids is 8.
This implies that;
q = Rate of Unit Discharge = 10
Av = Net Sectional Area of Voids = 8
That is, vs = q / Av
vs = 10 / 8
vs = 1.25
Therefore, the seepage velocity is 1.25.
Calculating for Rate of Unit Discharge when the Seepage Velocity and the Net Sectional Area of Voids are Given
q = vs x Av
Where;
q = Rate of Unit Discharge
vs = Seepage Velocity
Av = Net Sectional Area of Voids
Let’s solve an example;
Find the rate of unit discharge when the seepage velocity is 10, and the net sectional area of voids is 4.
This implies that;
vs = Seepage Velocity = 10
Av = Net Sectional Area of Voids = 4
q = vs x Av
So, q = 10 x 4
q = 40
Therefore, the rate of unit discharge is 40.

Calculate the net sectional area of voids when the seepage velocity and the rate of unit discharge are given
Av = q / vs
Where;
Av = Net Sectional Area of Voids
vs = Seepage Velocity
q = Rate of Unit Discharge
Let’s solve an example;
Find the net sectional area of voids when the seepage velocity is 4, and the rate of unit discharge is 60.
This implies that;
vs = Seepage Velocity = 4
q = Rate of Unit Discharge = 60
Av = q / vs
Then, Av = 60 / 4
Av = 15
Therefore, the net sectional area of voids is 15.
