Erratum for “Unsaturated Flow in Ground-Water Hydraulics”

Abstract

Various methods for obtaining hydraulic conductivity relationships on negative pressure side of water table are examined and curves relating hydraulic conductivity to negative soil-water pressure are shown for 28 soils; critical pressure heads calculated for 28 soils show that this factor may vary from -15 cm of water or more for sands to -100 cm water or less for structureless loams and clays; procedure is shown for systems with mainly horizontal flow, downward flow, and for flow through restricting layers.
