Prediction of unsaturated soil hydraulic conductivity with electrical conductivity [PDF]
Water Resources Research, 2009 Soil hydraulic conductivity (K) varies greatly with matric potential (h) and exhibits a high variability at the field scale. However, this key property for estimating water flux in soils is difficult to measure. In contrast, soil electrical conductivity (σ) is easier to measure and is influenced by the same parameters affecting K.
