Unfrozen Volumetric Water Content

For modeling soil conditions in frozen environments, a description of how the unfrozen water content varies with temperature is required. Database functionality is capable of storing both cooling and warming laboratory data while Blacks theoretical estimation will provide an estimate of the unfrozen water content curve when experimental data is limited.

Features:

Comprehensive plotting
Comprehensive querying capabilities
Support for English and Metric units
Non-linear regression of experimental laboratory data provides mathematical representation of experimental data
Blacks pedo-transfer function allows estimates of unfrozen volumetric water content as a function of temperature

Specific Heat

Modeling of thermal processes such as evaporative flux boundary conditions requires the specific heat of a soil at all soil suction levels. SoilVision has implemented a theoretical method to provide this calculation.

Features:

Estimation of specific heat by the Farouki method allows mathematical representation as a function of soil suction
Enhanced plotting
Comprehensive querying capabilities
Support for English and Metric units

Application:

Evaporation flux modeling such as soil cover design and evapotranspiration.

Thermoconductivity

Similar to specific heat, this soil property is required for the modeling of evaporative flux boundary conditions. Full database functionality is provided to manage your experimental data. Johansens theoretical estimation has also been implemented to provide a thermoconductivity model dependent on soil suction.

Features:

Non-linear regression provides mathematical representation of warming and cooling soil property functions
The Johansen pedo-transfer function provides an estimation of the thermoconductivity function when experimental data is limited
Enhanced plotting
Comprehensive querying capabilities
Support for English and Metric units

Application:

Evaporation flux modeling such as soil cover design

Constitutive Surfaces

Research presented over the past few decades by Coleman (1962), Matyas and Radhakrishna (1968), and Fredlund, 1993, has paved the way for the development of unsaturated soil constitutive surfaces. These surfaces describe the variation in void ratio or gravimetric water content of a soil undergoing a change in either net normal stress or soil suction. SoilVision allows you to develop unsaturated constitutive surfaces to describe the behavior of a soil undergoing compression and/or drying. The constitutive surfaces are developed in equation form which then allows the generated surface to form the basis for coupled seepage and volume change analysis.

New Features:

Mathematical representation of constitutive surfaces allows input into numerical solvers
Ability to generate constitutive surfaces for soil compression and/or drying
Professional report generation
Comprehensive plotting capabilities

Application:

Unsaturated coupled seepage and volume change modeling
