Water Content

Water 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
