Important Soil Characteristic Parameters

The volume ratio between the three phases is described by the following parameters:

e (void ration) = \frac{V_{p} (void volume)}{V_{t} (solid volume)}

Formula:

Void ratio

n (porosity) = \frac{V_{p} (void volume)}{V (total volume)}

Formula:

Porosity

S_{r} (degree of saturation) = \frac{V_{F} (water volume)}{V_{p} (void volume)}

Formula:

Degree of saturation

V = Total volume
V_t = Solids volume
