Explanation:

Permeability of Soil

The property of soil which permits the flow of water through its inter-connected voids is called permeability. It is an essential characteristic of soils that determines how easily water or other fluids can move through the soil medium.

• Inter-connected voids are crucial for permeability, as they allow water to flow through soil.

• Higher permeability is observed in coarse-grained soils like sand and gravel.

• Lower permeability is observed in fine-grained soils like clay.

• Applications: Permeability is critical in designing drainage systems, foundations, and soil stability analysis.

Analyzing the Given Options

1. "Seep ability" (Incorrect)

   • Although "seep ability" may sound relevant, it is not a standard term used in soil mechanics.

2. "Porosity" (Incorrect)

   • Porosity refers to the ratio of voids in the soil but does not indicate the ability of water to flow through the voids.

3. "Permeability" (Correct)

   • This is the correct term that defines the property of soil allowing water to flow through its interconnected voids.

4. "Void ratio" (Incorrect)

   • Void ratio refers to the ratio of the volume of voids to the volume of solids in the soil, but it does not imply the ability of water to flow.

Conclusion: The correct answer is Option 3: Permeability.
