shypFun.02110: Unimodal Kosugi-Mualem Model (2 Parameter Model)

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

Description

Calculates the soil hydraulic property function values based on given pressure heads \insertCiteKosugi.1996spsh.

Usage

shypFun.02110(p, h)

Arguments

p	vector of the 6 Kosugi-Mualem model parameters, order is sensitve and has to be given as: thr residual water water content [cm cm-3] ths saturated water water content [cm cm-3] hm air entry pressure head [cm] sigma width of pore size distribution [ - ] Ks saturated conductivity [cm d-1] tau exponent of Se in the capillary conductivity model, sometimes denoted in the literature as l [-]
h	pressure heads [cm] for which the corresponding retention and conductivity values are calculated.

Details

The function solves analytically the spec. water capacity function and integral to the capillary bundle model.

Value

returns a list with calculations at specified h:

theta	calculated volumetric moisture content
Se	calculated saturation
cap	specific water capacity function
psd	pore size distribution
Kh	Hydraulic conductivity values
