Erratum for “Analysis and Upscaling of Unsaturated Flow through Randomly Heterogeneous Soil” by Veena S. Soraganvi, Rachid Ababou, and M. S. Mohan Kumar

“If the hydraulic conductivity $K(\psi )$ in the $x$, $z$-plane is a random space function, there will be…[the rest of the sentence will remain unchanged].”

“If the soil parameters vary in the $x-z$ plane, the hydraulic conductivity in Eq. (1) takes the form $K(\psi ,x,z)$, which is a nonlinear function of suction for each position ($x$, $z$), and a random function of space ($x$, $z$) for each suction $\psi$; there will be…. [the rest of the sentence unchanged].”

“Finally, for $h_{\text{cap}}\equiv 1/\beta \ll {\lambda }_Z$ the flow field behaves as stratified.”

“Finally for $\beta {\lambda }_Z\ll 1$, or $h_{\text{cap}}=1/\beta \gg {\lambda }_Z$, the flow field behaves as stratified.”
