Sentence examples for models for unsaturated from inspiring English sources

The integration of elasto-plastic models for unsaturated soils poses additional challenges associated to the presence of suction as an extra constitutive variable with respect to traditional saturated soil models.

Most constitutive models for unsaturated soils are based on identification of soil-water suction with the capillary component of the matrix potential, ignoring the contribution of adsorption to this potential.

In this contribution, a range of explicit stress integration schemes are derived with specific reference to the Barcelona Basic Model (BBM), which is one of the best known elasto-plastic constitutive models for unsaturated soils.

Vu and Fredlund ([2004]) developed an elasticity based vertical displacement model for unsaturated expansive soils.

Due to a lack of published spectra or commercially available standards, modeling for unsaturated hydroxyl fatty acid residues was excluded.

A rigorous and fully unified coupled thermo-hydro-mechanical model for unsaturated porous media is required to simulate the complex coupling mechanisms involved.

The stress strain behavior of the soil is represented by an elasto-plastic constitutive model for unsaturated soil based on bounding surface concept and the moisture-suction behavior is modeled using van Genuchten model.

To contribute to a better understanding of the processes involved in the EBS, a case study for sensitivity analysis has been defined and is studied using a thermo-hydro-mechanical (THM) finite element approach including a consistent thermo-plastic constitutive model for unsaturated soils.

HILLFLOW is described by its authors as a physically based, distributed hydrological model at the hillslope and small catchment scale, although there are some sub-models containing empirical approaches (e.g. Mualem van Genuchten model for unsaturated water flow).

The study results suggest that the current site-scale model for the unsaturated zone of Yucca Mountain may underestimate radionuclide transport time within the unsaturated zone, because an increased fracture matrix interface area and the increased effective fracture porosity arising from lithophysal cavities are not considered in the current site-scale model.

In this paper a CA model for 3D unsaturated flow simulation is proposed using an extension of the original computational paradigm of cellular automata.
