Hi,
Here is a very simple case of a flume with a very coarse mesh, it can give you an idea. It is a coupled case so you only have to call telemac: >telemac2d aggradation.cas.
If you want to see deposition though, you will need to impose an incoming bedload discharge qs, and for this, you will need a fortran file with the subroutine conlit.f. I enclose mine as well, it is also very simple since I directly impose the solid discharge on each of the three points of the upstream boundary.
You can see erosion or deposition depending on your liquid or solid incoming discharge, keep in mind that the liquid discharge is given in m3/s for a whole boundary, whereas the solid discharge is given in m2/s for each point of the boundary.

Hope this help,
