Hydraulic models in unsatfit

See also this paper and models in SWRC Fit. WRF = water retention function, HCF = hydraulic conductivity function, CH = common H.

Basic unimodal models

Brooks and Corey (BC) model

van Genuchten (VG) model

Modified van Genuchten model

In general, modified model can be made by calling modified_model(hs) after set_model()

Kosugi (KO) model

Fredlund und Xing (FX) model

Bimodal models

dual-BC model

dual-BC-CH model

dual-VG model

dual-VG-CH model

dual-KO model

dual-KO-CH model

VG1BC2 model

HCF variation: r=1 and independent p

VG1BC2-CH model

HCF variation: r=1 and independent p

KO1BC2 model

HCF variation: r=1 and independent p

KO1BC2-CH model

HCF variation: r=1 and independent p

Giving pressure head of zero water content

Peters model (Kosugi type)

Fayer and Simmons model (van Genuchten type)
