Question

In the phenomenon of Absorption, the extent of saturation goes on increasing from the ground level below the soil with depth.

(a) True

(b) False

This question was addressed to me during an interview.

This question is from Canal Irrigation System topic in portion Canal Irrigation System of Irrigation Engineering

Answer 1

Correct answer is (b) False

To elaborate: The soil which is in immediate contact with the channel section forms a bulb of saturated soil. The soil layer below the saturated bulb is partially saturated. Thus the extent of saturation goes on decreasing from the ground level and a zone of unsaturation exists between them.
