many variable flux boundary condition

Post by liuxiaogang » Wed Aug 05, 2009 9:57 am

<font color="blue"><font size="2"><font size="1"><font face="Times New Roman">Dear Prof. Jirka,
I am a student in China, Now I am simulating water under deferent irrigation mode, and there are lots of trouble to do it.
How to handle problem of many variable flux boundary condition using hydrus-2d? Please give me some examples the best.
I have set many rGWL in deferent time, but why I only can find the first rGWL impact on graphics display of results?

Xiaogang,

I’m currently on vacations until August 22 and can not help you much during this time. You should be able to download a lot of examples from our HYDRUS website. See that I’m developing a library of HYDRUS project that should help you in preparing your projects.

Note that HYDRUS-2D could have only one boundary with time-variable flux and one boundary with atmospheric fluxes (also time-variable). Thus you could have two different boundaries with different time-variable fluxes. In newer version of HYDRUS (2D/3D) you can have atmospheric BC and up to 4 time-variable fluxes, i.e., 5 different fluxes altogether. There is no limit how many times you change the flux in time.

Best regards,

Jirka
