open TELEMAC-MASCARET The mathematically superior suite of solvers

I want to conduct the morphodynmics study for the 20k Square kilometer stretch. The sieve analysis data shows that some area non-cohesive sediment dominant, some area cohesive sediment dominant and the sediment size (D50) also varying each location. My quarries that how include the different class of cohesive and non cohesive sediment in one model setup.
Thank you advance for attention and reply
