open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello

I have been running many simulation testing different bottom coefficient factors. However I am trying to compare the results file from the value of 0.1 and 0.5 using manning's low but the results look very similar.

So that my question is Does telemac has some limit values relating to the bottom coefficient friction value?

Attached you can see my steering file (both of them) with 0.1 and 0.5 bottom coefficient factor values.

Thank you
Joel

Hello,

Manning 0.1 and 0.5 corresponds to Strickler 10 and 2, isn't that a very very high friction ?

Then one should see the depth, maybe it has little effect because the velocity is very small.
