The constant head permeability test is most suitable for:
Correct answer: A. Clean sands and gravels
- A. Clean sands and gravels
- B. Fine silts with very low permeability
- C. Highly compressible clays
- D. Organic soils with high water content
Explanation
Clean sands and gravels permit water to pass at a rate that can be measured conveniently under a constant hydraulic head. Falling head testing is generally more suitable for fine-grained soils with low permeability.

About Soil Mechanics and Foundations
Soil mechanics examines index properties, phase relationships, classification, permeability, seepage, compaction, consolidation, shear strength and earth pressure. Foundations apply these principles to bearing capacity, settlement and shallow or deep foundation selection, with clear distinction between compaction, which expels air, and consolidation, which expels water over time.
