Three profiles of the functions θ(λ) for Columbia silt loam. (A) Two theoretical solutions show the effect of β in the definition of soil water content profile in the drier part of the wetting front. The continuous line represents β = 104581.84 (the maximum value that the equations system from the theory of Barry et al. (2010) allows) and the dashed line represents β = 4.406. (B) Obtained by the theories of Barry et al. (2010) (dashed line) and Prevedello/Barry (solid line) when both theories ignore the initial soil water content observed in this soil before infiltration. (C) Obtained by the theories of Barry et al. (2010) (dashed line) and by Prevedello/Barry (solid line) when, in the second theory, the observed initial soil water content (θi = 0.031 m3 m−3) is considered before infiltration. Equation [1] by Barry does not define the wetting front profile as well as Eq. [3] by Prevedello.

(a) Water content measurements in a silt loam soil during two irrigation events for the seven sensors shown in Fig. 6. Diurnal fluctuations in sensor response occur as a result of temperature changing the bulk soil electrical conductivity to which certain instruments are sensitive.

Deviations from absolute values are considered to occur because of small sensor sampling volume.
