How to Calculate and Solve for Degree of Saturation | Soil Mechanics and Foundation

The image above represents the degree of saturation. Two essential parameters are needed to calculate the degree of saturation: the volume of the water (Vw) and the volume of the void space (Vv).

The formula for calculating degree of saturation:

S_r = ^V_w / _Vv

Where:

S_r = Degree of Saturation
V_w = Volume of the Water
V_v = Volume of the Void Space

Let’s solve an example;
Find the degree of saturation when the volume of the water is 48 and the volume of the void space is 12.

This implies that;

V_w = Volume of the Water = 48
V_v = Volume of the Void Space = 12

That is, S_r = ^V_w / _Vv
S_r = ⁴⁸ / ₁₂
S_r = 4

Therefore, the degree of saturation is 4.

Calculating the Volume of the Water when the Degree of Saturation and the Volume of the Void Space are Given

V_w = S_r x V_v

Where;

V_w = Volume of the Water
S_r = Degree of Saturation
V_v = Volume of the Void Space

Let’s solve an example;
Find the volume of the water when the degree of saturation is 12 and the volume of the void space is 12.

This implies that;

S_r = Degree of Saturation = 12
V_v = Volume of the Void Space = 12

That is, V_w = S_r x V_v
V_w = 12 x 12
V_w = 144

Therefore, the volume of the water is 144.

Calculating the Volume of the Void Space when the Degree of Saturation and the Volume of the Water are Given

V_v = ^V_w / _Sr

Where;

V_v = Volume of the Void Space
S_r = Degree of Saturation
V_w = Volume of the Water

Let’s solve an example;
Find the volume of the void space when the degree of saturation is 4 and the volume of the water is 40.

This implies that;

S_r = Degree of Saturation = 4
V_w = Volume of the Water = 40

V_v = ^V_w / _Sr
This means that V_v = ⁴⁰ / ₄
V_v = 10

Therefore, the volume of the void space is 10.
