Hello, I am not sure where the problem comes from, but as far as I can see, there may be two reasons:
- First, you should make sure that you do a restart on both hydrodynamics and sediment transport. Both Telemac2d and Sisyphe restart file should be consistent.
- Second, you should print out also the layer thickness in your output variables, ie by adding *ES in your printout variables (as well as *A* and CS* for concentration per class and percent per class and per layer)
By the way, in order to have sand grading effects, it is better to put at least two layers in your bed model and to specify the thickness of the active layer .
I hope this will help, Best luck, Cath
