# 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).

## SWRC Fit

SWRC Fit is a web interface which uses unsatfit and determines parameters for water retention function.
