open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello I'm trying a coupled simulation between t2d-tomawac-sisyphe and I notice some high evolution rates at some single nodes (+0.2m or -0.2m for 4000s an morphological factor =5). My D50=0.5mm and I chose the van-rijn formula. Is there any way to reduce those rates?
I am not sure about boundary conditions My inflow boundary in telemac is 566 so I guess In sisyphe i have to use 555 and liebor=5 ? Do I need to use also 5 in liebor for telemac ? My outflow is 544 in telemac so I used the same for sisyphe 5444. Do I have to use liebor=4 in T2d also?

Below i attach some of my files.

Are there any suggestions about limit deposition?
