Degree of Saturation Formula
The following example outlines the information needed to calculate soil saturation. Chemistry modes use DBE = (2C + 2 + N − H − X) / 2, with X = F + Cl + Br + I, assuming neutral closed-shell molecules and conventional valences. Oxygen and divalent sulfur do not affect DBE. The hydrogen-reference ratio is H / (2C + 2 + N − X) × 100, when the denominator is positive; it is not a universal chemical degree of saturation.
Variables:
- DOS is the Degree of Saturation (%)
- WV is the total volume of water in the soil (ft^3)
- VV is the total volume of voids in the soil (ft^3)
Select Soil saturation, divide water volume by void volume and multiply by 100. Volumes must refer to the same sample; water cannot exceed the pore volume. Select a reverse solve to find water or void volume from a known saturation.
How to Calculate Degree of Saturation?
The following steps outline how to calculate the Degree of Saturation.
- First, determine the total volume of water in the soil (ft^3).
- Next, determine the total volume of voids in the soil (ft^3).
- Next, gather the formula from above = DOS = WV / VV * 100.
- Finally, calculate the Degree of Saturation.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
total volume of water in the soil (ft^3) = 50
total volume of voids in the soil (ft^3) = 100
DOS = WV / VV * 100 = 50 / 100 × 100 = 50%
