A conceptual model of hysteresis
- Y. Mualem
- Physics
- 1 June 1974
A conceptual model of the capillary hysteresis phenomenon is suggested. The advantage of this model is that all scanning curves are derived with the aid of simple functions from the main drying curve…
Theoretical Prediction of Electrical Conductivity in Saturated and Unsaturated Soil

- Geology
- 1 October 1991
A conceptual model is proposed for the prediction of the electrical conductivity of bulk soil in saturated and in unsaturated states. The model is based on the hypothesis that the tortuosity factor…
A MODIFIED DEPENDENT‐DOMAIN THEORY OF HYSTERESIS
- Y. Mualem
- Computer Science
- 1 May 1984
The dependent-domain theory of hysteresis developed here accounts for the effect of the pore-water blockage against air entry while using the similarity hypothesis of the universal model, and seems to agree with observations much better that Model II, which uses the same amount of data for calibration.
Hydraulic conductivity of unsaturated porous media: Generalized macroscopic approach
- Y. Mualem
- Geology
- 1 April 1978
The macroscopic approach which yields the power function relationship between the relative permeability and the effective saturation, Kr = Sen, is generalized to allow n to vary with the soil type.…
Modified approach to capillary hysteresis based on a similarity hypothesis
- Y. Mualem
- Physics
- 1 October 1973
We present herein a simplified approach to the capillary hysteresis phenomenon. This approach is based on a similarity hypothesis resembling that of Philip (1964), but different basic assumptions…
Extension of the similarity hypothesis used for modeling the soil water characteristics
- Y. Mualem
- Mathematics
- 1 August 1977
Two independent domains models are derived by using an extended similarity hypothesis according to which the pore water distribution function is interpreted to be ƒ(r, ρ) = h(r)h(ρ). When this…
Hydraulic Conductivity of Unsaturated Soils: Prediction and Formulas
- Y. Mualem
- GeologySSSA Book Series
- 11 September 2018
Solution of unsaturated flow problems usually requires predetermination of the soil hydraulic properties, namely, (i) the relationship between the capillary head, 1/1, and the moisture content, 8 and…
