Question:
The hydraulic conductivity in unsaturated soil is mainly controlled by
The hydraulic conductivity in unsaturated soil is mainly controlled by
Show Hint
For unsaturated soils,
\[
\boxed{
K \uparrow \quad \text{as Degree of Saturation} \uparrow
}
\]
Hydraulic conductivity is much lower than in saturated soils.
Updated On: Jul 23, 2026
- Porosity
- Degree of saturation
- Thickness
- Pressure head
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
In unsaturated soils, the amount of water occupying the pore spaces governs the ease of water movement.
As the degree of saturation increases, hydraulic conductivity also increases.
Hence,
\[
\boxed{\text{Degree of saturation}}
\]
is the correct answer.
Therefore,
\[
\boxed{(B)}
\]
