open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello,

I am trying to modelling coastal solid transport with TELEMAC3D and SISYPHE.
I tried Strickler and Nikuradse as LAW OF BOTTOM FRICTION with FRICTION COEFFICIENT FOR THE BOTTOM=91.8025 and 0.0007033.(d50=0.1475 mm).Solid didnt move in both result.Is there anything in my steering files?

I had tried to set FRICTION COEFFICIENT FOR THE BOTTOM = 40(in strickler law).
According to bed shear law :


bed shear stress(with friction coefficient=40) should bigger than bed shear stress(with friction coefficient=91.8025).But the solid discharge is totally in contrary.My question is should solid discharge bigger if bed shear is bigger?

Thank you very much in advance.

Kind regards,
