TOPIC: Problems of deposition and hydrodynamic stability
Problems of deposition and hydrodynamic stability 9 years 6 months ago #16938

Hello everybody !
I am trying to run Sisyphe in internal coupling method with Telemac2d. I first launch a calculation with only Telemac2d in order to stabilize the water level. Then i launch a second calculation based on the first one which is the hydrodynamic file, but this time coupled with Sisyphe in order to calculate the erosion/deposition in the river. I face 2 problems: In the second calculation the free surface is going down instead of varying a little bit. (I have try a calculation without sisyphe and the free surface don't move at all in that case). At the beginning of the upstream i fixed (in the noerod.f) the level of non-erodable bed as the upper level of the bathymetry (i attached a picture so you can understand the situation), so no erosion can happen there.But i have deposition on the non-erodable bed and i have no idea where it comes from. I think the sediment transport is nul at the upstream condition (option default). I attached both steering file for the internal coupling. I hope somebody can help or advise me. Thanks in advance, Thibaud
