inquiry about water flow parameters

Post by taka » Fri Oct 11, 2019 8:12 am

To whom it may concern,



Hello, my name is Taka.

I'm a graduate student in Japan.



I'm writing this email to ask about water flow parameters.



Currently, I'm doing simulations of water flow with HYDRUS-1D

and applying Kosugi model to the hydraulic model.

Unfortunately, I have trouble setting values of α(h0),

because in the "Water Flow Parameters" section in "Pre-processing", the unit of α(h0) is [1/m]

though it is [m] in the Kosugi equation in the manual.



For example, if I want to set the value of α(h0) to -0.1 m,

which value should I input into the "Water Flow Parameters" section,

-0.1, -10(=-1/0.1), 0.1 or 10(absolute value)?



I would appreciate it if you could reply when you have time.



Sincerely,


Taka

The parameter α (denoted as h0 in Kosugi [1996]) has units of [L] and should be entered as such in GUI. J.
