Burdine (1953) Fit 
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 airentry value calculated from the Burdine (1953) and van Genuchten (1980) fit of the soilwater characteristic curve (kPa).
Max. Slope: The Max. Slope refers to the maximum slope (on a semilog plot) of the Burdine (1953) and van Genuchten (1980) fit of the soilwater characteristic curve (unitless).
