water content

[′wȯd·ər ‚kän‚tent]
(hydrology)
The liquid water present within a sample of snow (or soil) usually expressed in percent by weight; the water content in percent of water equivalent is 100 minus the quality of snow. Also known as free-water content; liquid-water content.

moisture content

1. The weight of water, usually expressed as a percentage of the total dry weight of a material.
2. The weight of water in a given soil mass.
