Question

The soil hydraulic head is expressed by

• A. Potential energy per unit mass of soil water.
• B. Potential energy per unit volume of soil water.
• C. Potential energy per unit weight of soil water.
• D. Height of standing water on the soil surface.

Hint:

Hydraulic head can be measured in terms of energy or actual water height — all are valid representations.

Answer 1

The Correct Option is C

Hydraulic head in soil physics can be expressed in terms of energy per unit mass, volume, or weight. It can also be physically interpreted as the height of water above a reference point.
