open TELEMAC-MASCARET The mathematically superior suite of solvers

Dear members,

I am trying to simulate flow + sediment transport for a straight channel using Telemac2d+GAIA.
I want to calculate it under no erosion conditions at the inflow boundary. In other words, I want to supply equilibrium sediment discharge to the inflow boundary.
According to page 29 of GAIA manual v8p4, by setting LIEBOR=5 and EBOR=0, this sediment supply condition is available. However, I set them based on this, the inflow boundary erodes and it seems inflow sediment discharge is less than equilibrium sediment discharge.
How can I deal with this problem? I appreciate any help you can provide.

Best regards
Ryota
