open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello,
I am trying to implement a simulation of sediment transportation in a steady flow along a straight channel.

1- Hydodynamik Model!
After successfully running my calculations for the hydrodynamic model in telemac2d with corect courant number = 0.65 and 'CORRECT END OF RUN'.The results were not right at the Inlet (Open Boundary with prescribed Q).
There is a big mistake in water depth and flow velocity at the open Boundary.
I have manipulated my mesh but the Error still moves along the Boundary.

Hi
Could you join also your steering file?
What option did you choose for the liquid boundary in term of velocity profile?
This parameter could have an influence on such situation where the liquid boundary is partially dry...

regards

here is my steering file.

I am waiting your answer, Please

Hi
you could try:
VELOCITY PROFILES =1; 5 instead of 1; 4
but not sure this will be sufficient

Regards
