Arguments

p

vector of the 6 Brooks-Corey model parameters, order is sensitve and has to be given as:

thrresidual water water content [cm cm-3]
thssaturated water water content [cm cm-3]
alfair entry pressure head [cm^-1]
beteffective model parameter [ - ]
Kssaturated conductivity [cm d-1]
tauexponent 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

returns NA; not supported

psd

returns NA; not supported

Kh

Hydraulic conductivity values

Note

The Muealm integral is solved numerically
