Which of the following tests is used to determine the permeability of soil?

Which of the following tests is used to determine the permeability of soil?

Step 1: Understand what permeability means. Permeability is how easily water can flow through soil.
Step 2: Know that there are different types of soil: granular soils (like sand) and finer soils (like clay).
Step 3: Learn about the constant head test. This test is used for granular soils to measure how quickly water flows through them.
Step 4: Learn about the falling head test. This test is used for finer soils to measure their permeability.
Step 5: Remember that the constant head test is for sandy soils, while the falling head test is for clayey soils.
