open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi,
I have a question about liquid boundaries. I have a case where I know the water elevation in the ocean and the water flow in the river (as you can see in the attachment) but I don't know how I should consider the other boundaries (I am talking about the ones where I drew the arrows.)The flow is coming from the ocean to the river or the inverse but i don't know what to do to those parts that limit the study area. If I consider them as solid boundaries and run an oispill simulation, if the particles reach those boundaries they will be stuck and the result won't be correct
regards

Hi
Both are part of the ocean boundary.
Hope this helps
