“…In soils where increased clay content results in decreased hydraulic conductivity, the measured apparent electrical conductivity (EC a ) is inversely proportional to hydraulic conductivity (K) (Curtis and Kelly, 1990;Slater and Lesmes, 2002). The relation between EC a and particle size distribution was utilized by Callegary et al (2007a) to estimate potential for ephemeral stream channel infiltration and subsurface horizontal flow.…”
