sncFun.02110: Unimodal Kosugi Non-Capillary Saturation Model

In spsh: Estimation and Prediction of Parameters of Various Soil Hydraulic Property Models

Description

Analytical implementation of the non-capillary saturation function for the \insertCiteKosugi.1996spsh.

Usage

sncFun.02110(p_snc, h)

Arguments

p_snc	vector of the 2 Kosugi saturation model parameters, and h0 sensitve and has to be given as: hm air entry pressure head [cm] sigma width of pore size distribution [ - ] h0 pressure head representing oven dryness given in pF, i.e. log[10](|pressure head| [cm])
h	pressure heads [cm] for which the corresponding retention and conductivity values are calculated.

Details

The function is Eq. Table 1-B in insertRefStreck.2020spsh The analytical solution presented in sncFun.02110 only requires the Kosugi specific model parameters and h0

Value

returns a list with calculations at specified h:

snc	non-capillary saturation
