Besides standard approaches, the soil water retention curve (SWRC) can be estimated either from pore size distribution obtained by mercury intrusion porosimetry or freezing characteristic curve. These methods are based on simplified laws such as Young-Laplace for capillary suction ClausiusClapeyron cryo-suction. might not valid clayey sands where presence of clay particles would induce other me...

known (Tillotson and Nielsen, 1984): (1) the dimensional analysis technique, which is based on the existence of Results with an empirically based one-parameter model showed physical similarity in the system; and (2) the empirical that the pore-size distribution index ( ) described in the Brooks and Corey formulation of soil hydraulic properties can scale the soil–water method, called functional...

ABSTRACT: The physical and chemical characteristics of a soil determine its hydraulic properties, such as conductivity, infiltration, moisture. Due to the usefulness soil's moisture retention characteristic curve, several methodologies have been developed obtain it. Mathematical models for prediction this property constitute type that is economical very affordable. One most practical model Arya...

The field of unsaturated soil mechanics has recently seen the introduction pore network models, which attempt to replicate void structure porous materials. They are robust physically-based simulation tools and have been used simulate constitutive relationships like water retention curves (SWRC) hydraulic conductivity functions. This work aims present a networkmodeling approach for predicting hy...
