open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello,
I have used the TELEMAC 2D hydrodynamic solver extensively...Now I wanted to couple TELEMAC 2D and SISYPHE for modeling sediment transport...I am using v7p0 version...I have gone through the v7p0 SISYPHE user manual...As a starting exercise, I wanted to couple SISYPHE with the TELAMC 2D dambreak example test case...I wanted to use a bed load transport formulation...However, when I am running the simulation the bed level remains unchanged...It is as if the bed is rigid and no sediment transport is occurring...I have tried different ways by changing the parameters in the steering file but did not find any result, I am attaching the TELEMAC 2D and SISYPHE steering files...Would anyone kindly clarify the mistake I am making??

Hello,
in this test case there is no roughness. According to that the shear stress will be calculated to zero, so you have no bed load transport.
Starting with coupled simulation I would recommand to use test cases from sisyphe or better using a new version and gaia.
Best regards,
