We reviewed the use of the van Genuchten–Mualem (VGM) model to parameterize soil
hydraulic properties and for develo** pedotransfer functions (PTFs). Analysis of literature …

The commonly used hydraulic models only account for capillary water retention and
conductivity. Adsorptive water retention and film conductivity is neglected. This leads to …

Most classical predictive models of unsaturated hydraulic conductivity conceptualize the
pore space as either bundles of cylindrical tubes of uniform size or assemblies of cylindrical …

A number of investigations have shown that the shear strength of unsaturated soils can be
defined in terms of effective stress. The difficulty in this approach lies in quantifying the …

Abstract The Peters–Durner–Iden (PDI) model system for describing soil hydraulic
properties (SHP) has been developed over a decade. Inspired by Rien van Genuchten's …

In the scope of the increasing concern for soil conservation, reduced tillage (RT) agriculture
is growing more important in today's agriculture in Western Europe. However, crop rotations …

The present study proposes a new two-step approach to prediction of the continuous soil
water characteristic (SWC) from saturation to oven-dryness from a limited number of …

Common conceptual models for unsaturated flow assume that the matric potential is
attributed to the capillary force only. These models are successful at high and medium water …

The mathematical representation of the soil hydraulic properties is of central importance for
modeling water, solute and energy transport in soils. The established models of the water …

Accurate description of the soil water retention curve (SWRC) at low water contents is
important for simulating water dynamics and biochemical vadose zone processes in arid …
