Unimodal Brooks-Corey Non-Capillary Saturation Model
Description
Analytical implementation of the non-capillary saturation function from the Brooks-Corey function (Brooks and Corey 1964).
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:
| |||||||
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 |
