Hello all, I am modeling scour around a pier due to dam break wave.my hydrodynamic model is working well but after coupling with sisyphe there is no evidence of sediment transport.I would appreciate if you could help me to figure out the problem.

Hello,
Looks like your steering file for sisyphe is incomplete. What are you solving, suspended or bedload transport?
Is mobility parameter (Shields parameter) in the range of sediment movement (according to your hydrodynamic forcing) ?
Take a look to the examples.

Hope it helps,

Pablo
