SOILPARA, soil parameter estimator - determine hydraulic properties of unsaturated and saturated soils
SOILPARA Categories: parameter estimation models - transport parameters, parameter estimation models - unsaturated zone parameters, soil
SOILPARA Overview
SOIL PARAmeter Estimator is based on statistical pore/particle size distribution models and can be used to estimate hydraulic parameters in the van Genuchten constitutive model
(Brooks-Corey parameters can be estimated from these) for variably-saturated soils. SOILPARA allows estimation of the unsaturated zone parameters (1) from retention data and/or conductivity or diffusivity data (K or
D vs. soil water content/pressure) based on the public domain RETC model by M. Th. van Genuchten et al., 1991) with a Windows native preprocessor that is easy to use and offers graphical output and extensive
on-screen help; (2) from soil texture (based on the work of Shirazi and Boersma, 1984, and Campbell, 1985) by clicking on a soil texture diagram to return percentage sand, silt and clay within the pre-processor; or
(3) by selection of USDA-recommended typical parameter values for various texture classes available in the SOILPARA database.
