Please refer to the attached. I have to derive some water from the an existing river reach to another (future) channel.
The purpose is to ensure that the diverted fluxes belong a predifined range of discharge.
I have Q (t) upstream and h (t) downstream (without any lateral intake as indicated in the top figure of the attached). Now i plan to model the lateral water intake as rectangular breach (see attached). The downstream hydro condtions, formerly known, are modified and therefore they are unknown.
Can I provide a free conditions (H or Q) at the breach and at the downstream boundary?
Can telemac 2d and 3d handle this type of problems?
Be sure that any kind of help will be appreciated
Regards
Mourad
