51. Which laboratory test is commonly used to determine the permeability of soil?
- Proctor test
- Unconfined compression test
- Falling head test
- Direct shear test
Answer
The correct answer is: C) Falling head test
Explanation
When permeability is relatively low in fine-grained soils, the falling head test is frequently employed to measure it. The test involves measuring the change in water head over time.
