SVSOILS™ is the world’s premier product for estimating the hydraulic properties for flow modeling in unsaturated soils. Our database contains data on over 6,200 soil-water characteristic curves and provides numerous theoretical methods of estimating the soil-water characteristic curve (SWCC) or unsaturated hydraulic conductivity curve.
This completely new release represents a fresh re-design of the classic and popular SoilVision® application. SVSOILS™ contains an expanded database of unsaturated soil properties and presents a new and simplified interface for a greatly improved and pleasing user experience.
The software is designed specifically for the estimation and mathematical representation of soil constitutive models for subsequent numerical modeling.
Saturated and unsaturated soil properties may be estimated based on the extensive existing database or estimated with one of the many estimation methods present in the software. The database continues to grow as more organizations donate soils to the system. The estimation methods include: 9 methods of estimating the soil-water characteristic curve; 15 methods of estimating saturated hydraulic conductivity; and 10 methods of estimating unsaturated hydraulic conductivity.

The new design is more tightly integrated with the SVOFFICE™5 suite of software and developed constitutive models may easily be integrated with the corresponding numerical analysis software package.
A new feature of SVSOILS™ is the ability to develop a consitutive model for oil-sand tailings as a saturated or unsaturated material.
SoilVision Systems Ltd. has spent years collecting high-quality unsaturated soil data from sources all over the world. Our database now contains data on over 6,200 soil samples. 98% of these soil samples have a soil-water characteristic curve measured in a laboratory. The soil database also contains saturated permeability (hydraulic conductivity) data on over 2,500 soils as well as unsaturated permeability data on over 700 soils.
It is crucial to have an accurate description of unsaturated soil properties when performing finite element modeling of water and contaminant flow through the unsaturated soil zone. Methods for estimating unsaturated soil properties may not always be reliable. The use of the database contained in the SVSOILS™ software can confirm the potential variability of your unsaturated soil properties. Groups of soils may be selected and plotted together to give a comprehensive idea of the variability of the soil-water characteristic curve. Determination of the air entry value (AEV) or the residual water content with increased accuracy is now possible.
