The image above represents steady flow in an unconfined aquifer. To calculate an unconfined aquifer, four essential parameters are needed and these parameters are Hydraulic Conductivity (K), Head at the Origin (h1), Head at L (h2) and Flow Length (L).
The formula for calculating steady flow in an unconfined aquifer:
qt = K(h1² – h2² / 2L)
Where:
qt = Steady Flow in an Unconfined Aquifer
K = Hydraulic Conductivity
h1Â = Head at the Origin
h2Â = Head at L
L = Flow Length
Let’s solve an example;
Find the steady flow in an unconfined aquifer where the hydraulic conductivity is 14, the head at the origin is 8, head at L is 3 and the flow length is 5.
This implies that;
K = Hydraulic Conductivity = 14
h1 = Head at the Origin = 8
h2 = Head at L = 3
L = Flow Length = 5
qt = K(h1² – h2² / 2L)
So, qt = 14(8² – 3² / 2(5))
qt = 14(64 – 9 / 10)
qt = 14(55 / 10)
Then, qt = 14(5.5)
qt = 77
Therefore, the steady flow in an unconfined aquifer is 77.
