How do you determine the degree of saturation?

The degree of saturation of the soil is obtained from the field and is not computed directly by testing the soil in the laboratory. It is computed indirectly using value of water content, specific gravity and void ratio. The relationship between saturation, moisture content and ratio of voids are as expressed below.   (from google)

Explanation:

there ya go   :)

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
