Hydraulic conductivity of soils varies directly with

A. Capillary porosity

B. Non-capillary porosity

C. Total porosity

D. Water holding capacity

Answer: Option C

Solution(By Examveda Team)

Hydraulic conductivity defines the proportional relationship between flux and hydraulic gradient, or in this case, of unidirectional flow of water in saturated soil. Saturated hydraulic conductivity is a quantitative expression of the soil’s ability to transmit water under a given hydraulic gradient.
Hydraulic conductivity of soils varies directly with the total porosity of the soil.
