open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello together,
i'm coupling telemac3d with sisyphe for a hydro-morphological model (v6p3). For the suspended transport i want to use Sedi3D. But i did not figure it out how to describe the granulometric parameters, like multiple size classes. The only parameter for non cohesive sediment here is one mean diameter of the sediment and the according settling velocity. If i add more diameters they are treated as cohesive, if i understand my results correctly. An other problem is the description of the sediment layers, like in sisyphe. Here it is quite easy to describe spatially varying grain-size distributions and layer thicknesses.

So i guess it is not possible to describe multiple size classes for sedi3d, in this version?


I would be glad for some hints.

Best regards

Markus
