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
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
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
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.
