Fit soil water retention and unsaturated hydraulic conductivity functions
Project description
unsatfit
unsatfit is a Python library for optimizing parameters of functions of soil hydraulic properties; water retention function and unsaturated hydraulic conductivity function. The equations are explained in Seki et al. (2022) and shown to be useful for practical applications in Seki et al. (2023).

Example output
This is an example output of this program; water retention curve (top) and hydraulic conductivity curve (bottom) of Gilat loam fitted with KBC (KO1BC2-CH) model.
SWRC Fit
SWRC Fit is a web interface which uses unsatfit and determines parameters for water retention function.
