Influence of the hysteresis effect on transient flows in saturated‐unsaturated porous media
N. T. Hoa, R. Gaudu, Claude Thirriot · Water Resources Research · 1977
In the following report the authors experimentally and numerically study one‐ and two‐dimensional transient flows where the hysteresis of the relationship of suction‐water content clearly appears. In the numerical simulation of these flows, by using a finite element method, the hysteresis effect is taken into account by considering both its primary and secondary scanning curves; when the seepage surface occurs, it too is taken into account. The comparison with experimental results shows that in the concerned problems a numerical simulation in which this hysteresis effect is ignored may involve important errors.
