Soil Water Characteristic Curve

SoilVision is the only commercially available database in the world capable of managing unsaturated soil properties. Advance into unsaturated soils with ease! The database functionality will manage your soil-water characteristic curve laboratory data in a simple, straightforward manner. Interested in performing unsaturated soils analysis without the high cost of extensive laboratory tests? Pick from seven theoretical estimations to estimate a soil-water characteristic curve or select a similar soil-water characteristic curve from our experimental database of over 6000 soils.

 

Features:

  • Seven pedo-transfer functions for estimating the soil-water characteristic curve including methods from Fredlund & Wilson, Gupta & Larson, Arya & Paris, Tyler & Wheatcraft, Vereecken, Scheinost, and Rawls & Brakensiek
  • Calculation of volumetric air content as a function of soil suction
  • Enhanced plotting
  • Professional report generation
  • Support for English and Metric units
  • Calculate water storage function necessary for seepage modeling
  • Comprehensive querying capabilities
  • Non-linear curve-fitting of soil-water characteristic curve with five different equations including van Genuchten, Fredlund & Xing, Gardner, Brooks & Corey, Mualem, and Burdine
  • Experimental dataset of over 6000 laboratory measured soil-water characteristic curves
  • Automatic calculation of variables such as the air entry value, wilting point, and field capacity of a soil
  • Estimation of the soil-water characteristic curve by the Fredlund & Wilson pedo-transfer function
  • Management of wetting and drying data
