This is a python library to calculate hydraulic properties using van Genuchten's equations (Van Genuchten, M.T., 1980. A closed-form equation for predicting the hydraulic conductivity of unsaturated soils. Soil science society of America journal 44, 892–898.). Specifically you can obtain parameter values for the default soils in that paper, have access to functions to solve the theta, C and K funcitons, and also plot these properties.
