Normalized Water Content

on . Posted in Geotechnical Engineering

partially saturated soil 1Normalized water content, abbreviated as \(\Theta\), also called effective saturation, a dimensionless number, is the water content for which the gradient becomes zero.

 

Normalized water content formula

\(\large{ \Theta = \frac { \theta \;-\; \theta_r } { \theta_s \;-\; \theta_r } }\) 
Symbol English Metric
\(\large{ \Theta }\)  (Greek symbol Theta) = normalized water content \(\large{dimensionless}\)
\(\large{ \theta_r }\)  (Greek symbol theta) = residual water content \(\large{ft^3}\) \(\large{m^3}\)
\(\large{ \theta_s }\)  (Greek symbol theta) = saturated water content \(\large{ft^3}\) \(\large{m^3}\)
\(\large{ \theta }\)  (Greek symbol theta) = volumetric water content \(\large{ft^3}\) \(\large{m^3}\)
