Basically in soil there is 3 part
- Solids partical
When water added to soil, at that time soil become saturated. And when air contain replace by water and soil become fully saturated at that time soil have two part one is water and one is solid partical.
If we add more water than fully saturation, hence saturation of soil is 100% or more than that, is called the supersaturated stage.
Water content more than shrinkage limit called supersaturated stage
