sncFun.04110: Unimodal Brooks-Corey 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 from the Brooks-Corey function \insertCiteBrooks.1964spsh.

Usage

sncFun.04110(p_snc, h)

Arguments

p_snc	vector of the 2 Brooks-Corey model parameters, order is sensitve and has to be given as: alf air entry pressure head [cm^-1] bet effective model parameter [ - ] 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-A in insertRefStreck.2020spsh The analytical solution presented in sncFun.04110 only requires the Brooks-Corey model specific parameters and h0.

Value

returns a list with calculations at specified h:

snc	non-capillary saturation
