open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi I have gone through a number of the forum posts in respect to suspended sediment concentration specification for an inflow boundary (i.e. river) and I am still unsure in respect to how to specify a sediment concentration in kgper m3. I am running the model coupled with Telemac2d and sisyphe.

Where do I specify the sediment concentration which may change with time and river flow magnitude at my inflow boundary

Is it as a tracer in the Telemac2d liquid file for the boundary condition?

If so how do I include multiple concentrations where there are more than 1 fraction being modelled (is this tracer 1 - 2 etc.)

If I want to include a source term for sediment such as dredging point do I also specify this in telemac2d as you would for a normal tracer source.

I would appreciate any assistance in this matter

kind regards
Tony
