Özet:

 


The hysteretic nature of
soil water characteristic curve (SWCC) is captured assuming the virgin drying
and virgin wetting (a.k.a. imbibition) curves; which can be obtained from
experiments or various fitting equations in the literature, bound all possible
values during transition from one regime to the other. The scanning curves
(transitions between virgin wetting and drying SWCC) are modelled by using
geometry-based relations, which are devised by means of the observations on the
shapes of graphs of experimental data found in the literature. The proposed
relations can be used in incremental form to predict suction in different
frameworks (e.g. infiltration, evaporation) and related physical problems. An
empirical equation is proposed for power parameter (K), which is introduced in the relations. Only virgin wetting and
virgin drying SWCCs and regime reversal point suffice to model a scanning curve
in the developed formulations.
