Water Content

Written by Jerry Ratzlaff on . Posted in Geotechnical Engineering

partially saturated soil 1Water content, abbreviated as w, also called moisture content, is the ratio of weight of soil to the weight of water or the quantity of water contained in a material.

 

water content formulas

\(\large{ w = \frac{M_w}{M_s }   }\)  
\(\large{ w = \frac{W_w}{W_s }   }\)  
\(\large{ w = \frac{ S \; e }{ G_s }   }\)  

Where:

\(\large{ w }\) = water content (% moisture contemt)

\(\large{ S }\) = degree of saturation (expressed as %)

\(\large{ M_s} \) = mass of solid

\(\large{ M_w }\) = mass of water

\(\large{ G_s }\) = specific gravity of soil

\(\large{ e }\) = void ratio

\(\large{ W_s} \) = weight of solid

\(\large{ W_w }\) = weight of water
