7 times higher than those of the mechanistic model (M5); considering the simplicity of model C5 in terms of vadosezone processes and parameters (only saturated water content, [[theta].
s] are the residual and saturated water contents ([L.
Parameters estimated by Hydrus-1D for coarse dune sand, with a steady state flux applying waste water (1 cm h-1) with 0(v), average soil water content (cm3 cm-3); 0s, saturated water content
(cm3 cm-3); , dispersivity (cm); V , pore water velocity (cm h-1) and D, dispersion coefficient (cm2 h-1).
Zeleke and Si (2005, 2006) examined the scaling property of saturated hydraulic conductivity, measured saturated water content
, residual soil water content, and field capacity.
The laboratory measurements of saturated water content for the topsoil were significantly greater than the field measurements and had a smaller variation between replicates (Table 1).
By normalising the water retention curve to saturated water content, most of the scatter was removed (Fig.
Saturated hydraulic conductivity was estimated from the regression equation developed by the unsaturated hydraulic conductivity data of each plot, corresponding the saturated water content
and the report of Bruce et al.
Equation 18 then results in the IWC being equal in magnitude to the saturated water content
, as it should be.
In December 1999, 3 months after this field experiment was established, the saturated water content of the control treatment was 0.
Owing mainly to the low bulk density of the WTR, its high stability (because of the sustained performance of the polymer), and limited potential for swelling, the saturated water content and [K.
The slope corresponds to a rate of increase in the saturated water content of aggregates of 9.
The line through the 3 points had a slope corresponding to an increase in the saturated water content of 10 g [H.
