Unimodal Kosugi-Mualem Model (2 Parameter Model)
Description
Calculates the soil hydraulic property function values based on given pressure heads (Kosugi 1996).
Usage
shypFun.02110(p, h)
Arguments
p |
vector of the 6 Kosugi-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. |
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 |
