The Saturation Ratio calculator computes the water saturation ratio of soil.
INSTRUCTIONS: Choose the preferred units and enter the following:
Saturation Ratio: The calculator returns the saturation ratio (RS) as a real number rounded to the nearest 1/10,000th. However, this can be automatically converted to % via the pull-down menu.
TheRS is the ratio of the water contained in a sample volume to the volume of voids `V_V` and represents the amount of volume that can still absorb more water. The is:
RS = Vw / Vv
In engineering application the saturation ratio indicate how far from saturation the soil is.
