trimodal van Genuchten-Mualem functions for the retention and hydraulic conductivity curves \insertCiteDurner.1994spsh.
1 | shypFun.01310(p, h)
|
p |
vector of the 9 van Genuchten-Mualem model parameters, order is sensitve and has to be given as:
| ||||||||||||||||||||||||
h |
pressure heads [cm] for which the corresponding retention and conductivity values are calculated. |
The function solves analytically the spec. water capacity function and integral to the capillary bundle model.
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 |
