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.

The residual water content, C, is the amount of non-connected water that remains at the hydraulic cut-off suction, [h.

The fitted residual water content was affected by adding the wet end h([theta]) points, giving a significantly higher [[theta].
For the Moora sand, the air entry was the most variable parameter with up to 60% coefficient of variation followed by the residual water content with 19%, the saturated water content with 7%, and the n parameter with 5%.
The parameters that were directly calibrated by fitting the model's prediction to observed data were: boundary pressure potential, boundary water content, residual water content, pore size distribution index in micropores, boundary hydraulic conductivity, tortuosity factors in macropores and micropores, dispersivity, and mixing-depth.
Equation 9 resembles that proposed by van Genuchten (1980), except that we replace van Genuchten's residual water content, [[theta].

r] is the residual water content, a is a curve-fitting parameter (equivalent to the reciprocal of the air-entry value), [Psi] is the matric potential or pressure head, n is another curve-fitting parameter, and m = (1 - 1/n).
