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...

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...

Abstract Geosynthetic clay liners are widely used as hydraulic barrier due to their low conductivity but bentonite in the loses its effectiveness significant thermal fluxes by both diurnal and seasonal heating cooling cycles. Modified sodium carboxy methyl cellulose-based (HYPER clay) has shown better performance situations. A possible reason for this improved of HYPER based geosynthetic liner ...

The way in which memories decline over time has been studied for over a century, but remains an unresolved issue because of a lack of sufficiently precise data and effective model selection techniques. Here we address this gap with a particular focus on whether the decline in memory retention is complete or asymptotes above chance performance. We collected stem cued recall and stem completion d...

in this paper, we give some characterizations for legendre spherical, legendre normal and legendre rectifying curves in the 3-dimensional sasakian space. furthermore, we show that legendre spherical curves are also legendre normal curves. in particular, we prove that the inverse of curvature of a legendre rectifying curve is a non-constant linear function of the arclength parameter.

soil hydraulic properties are key soil physical characteristics that are required to conduct soil and water related studies such as irrigation and drainage. in this study, three indirect methods: inverse modeling, pedo-transfer function, and the semi-physical method of arya et al., were compared in a sandy loam soil to estimate soil moisture retention and unsaturated hydraulic conductivity curv...
