Theory for Source‐Responsive and Free‐Surface Film Modeling of Unsaturated Flow (2010, methodology): “…to other concepts and previous models, for example the film-flow domain of Beven and Germann (1981), the fi lm-fl ow concepts of Dragila (1999) and Dragila and Wheatcraft (2001), the fi lm-fl ow portion of the model of Tuller and Or (2001), and the fi lm–capillary model of Peters and Durner (2008).”
Plant Growth‐Promoting Rhizobacteria (PGPR) Reduce Evaporation and Increase Soil Water Retention (2017, background): “Therefore, in the presence of EPS, the pore-scale flow conductance can be largely reduced as it is inversely proportional to viscosity leading to less mobile water (Tuller & Or, 2001).”
Fluid flow in porous media with rough pore‐solid interface (2016, background): “Another plausible possibility for relative permeability underestimation might be neglecting corner and film flow [see e.g., Or and Tuller, 2000; Tuller and Or, 2001, 2002], which may dominate capillary flow, particularly at low water saturations.”
A new capillary and thin film flow model for predicting the hydraulic conductivity of unsaturated porous media (2010, background): “As pointed out by Tuller and Or [2001] , this shortcoming may be attributed to the lack of consideration of soil‐water flow in thin films, likely to become important at low values of matric head.”
Using Pedotransfer Functions to Estimate the van Genuchten–Mualem Soil Hydraulic Properties: A Review (2010, methodology): “Th is ultimately implies that the model of Mualem (1976), as well as related statistical pore-size distribution models published previously or later, provides a simplistic conceptualization of the hydraulic conductivity of a porous medium (Schaap and Leij, 2000; Tuller and Or, 2001).”
Comparison of Unimodal Analytical Expressions for the Soil-Water Retention Curve (2005, unknown): “…r ϩ 1 2 (␪ s Ϫ ␪ r ) erfc΄ ln ΂ ␺ b Ϫ ␺ ␺ b Ϫ ␺ o ΃ Ϫ ␴ 2 √2␴ ΅ for ␺ Ͻ ␺ b potential is related not only to capillary forces, but also to adsorptive forces (see e.g., also Or and Tuller, 1999, 2002; [8] Tuller and Or, 2001). where " erfc " denotes the complementary error function, ␺ o represents…”
Simple consistent models for water retention and hydraulic conductivity in the complete moisture range (2013, methodology): “[6] The capillary bundle models often fail to express hydraulic conductivity in the medium to dry range, because they neglect film and corner flow [Tuller and Or, 2001].”
