... ( Dirksen and Dasberg, 1993 ). Using a three-phase mixing model, Stenger et al. (2007) determined the ε–θ relationship of seven materials with volcanic origins, including an allophanic soil that was similar to the Kuroboku andisol. They showed that the model described the measured ε–θ relationship fairly...
