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 6200 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 2500 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 SoilVision 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.

TESTIMONIALS
SoilVision is a valuable program
which assists in the design of soil cover systems for waste management
faculties such as landfills, tailing deposits and waste rock dumps.
In many cases the soil-water characteristic curves and hydraulic
conductivity values for the potential soils which may be used for
construction are not available during the early stages of design.
We use SoilVision to estimate the properties on the basis of the
grain-size distribution and other simple index properties. This allows
preliminary analysis to proceed almost immediately. The optimum soils
may be selected for the more detailed and time-consuming testing.
In many cases it is possible to provide a complete design while testing
only a limited number of samples to confirm soil properties.
The power of SoilVision is
in its large database of soil-water characteristic curves, and the
fact that this database can be added to by the user. The "query" option
allows grouping of soils with similar characteristics, such as grain-size
distribution and classification. SoilVision is a valuable tool for
use in unsaturated soil studies.
I am currently using Soilvision to estimate hydraulic conducitivity in areas where we have limited soil data and usually only estimates of soil texture. We are using the database of similar textures to interpolate soil moisture curves for input into drainage models to estimate impacts of drainage ditches to nearby wetland hydrology.
