The Burdine dialog contains the equation parameters necessary to mathematically represent the SWCC curve using the methodology published by Burdine (1953). A description of the theory can be found in the SVSOILS Theory Manual.

 

ab: The ab field refers to one of the fitting parameters in the Burdine (1953) and van Genuchten (1980) equation.

 

nb: The nb field refers to a second fitting parameter in the Burdine (1953) and van Genuchten (1980) equation.

 

Fit: The Fit indicates whether the experimental data have been fit with the Burdine (1953) and van Genuchten (1980) equation.

 

Error: The Error field shows the difference between the fit and the laboratory data in terms of R2.

 

Residual WC, wr: The Residual WC is the calculated residual volumetric water content when using the Burdine (1953) and van Genuchten (1980) equation.

 

AEV: The AEV field shows the air-entry value calculated from the Burdine (1953) and van Genuchten (1980) fit of the soil-water characteristic curve (kPa).

 

Max. Slope: The Max. Slope refers to the maximum slope (on a semi-log plot) of the Burdine (1953) and van Genuchten (1980) fit of the soil-water characteristic curve (unitless).
