open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello
I want to put on a source point a tracer with a certain flow rate). My model takes into account the tidal range in a coastal environment, and my source point of interest is sometimes emerged (dry). I'd like to create a tracer flow in my source point only when at least 1 m of water is present at the source point. Is it possible to do this, and if so, how? Thank you for your help.

Hi
One solution could be to add T3D_DEBSCE.f as a user_fortran and adapt the code to have a discharge only when the condition on water depth is valid.
Another solution could be to run the computation twice. First without the source. From this first result you manage create a source file and then you run the final computation...

Hope this helps

Ok, thanks for this help.
Also, when I'm using a source file to define a temporality in the tracer discharge at to source point (keyword SOURCES FILE), I have this error message : "WRONG NUMBER OF DISCHARGES OF SOURCES". I don't understand why...
My source file is attached.
Thanks a lot

This has already been answered in the forum (use search tool)
This is also detailed in manuals
Even you use the source file you should give values in the steering file...
