Erratum for “Probability Density Functions in the Analysis of Hydraulic Conductivity Data” by Hugo A. Loáiciga, William W.-G. Yeh, and Marcos Adrian Ortega-Guerrero

“ $I_{\mathrm{Kh}}=I_{\mathrm{Yh}}$ and $I_{\mathrm{Kz}}=I_{\mathrm{Yz}}=\text{horizontal}$ and vertical correlation scales of the hydraulic conductivity (and of the log conductivity), respectively.”

“ $I_{\mathrm{Kz}}∕I_{\mathrm{Kh}}=I_{\mathrm{Yz}}∕I_{\mathrm{Yh}}=\text{ratios}$ of the vertical to horizontal integral scales of the hydraulic conductivity and of the vertical to horizontal log conductivity integral scales, respectively.”
