The first question is whether it is possible to set the bed load grading in different regions of the simulation area, and how to achieve it?
The second question is, my suspended solids concentration changes over time. How can I set the total concentration and set the grading data for automatic proportional distribution?
The third question is, there is a significant difference in particle size between the grading curves of my suspended and bed load. Can they be set separately for grading?
The fourth question is whether the active layer model can set different gradations for different bed layers, such as the median particle size of the first bed layer being 50
What is the median particle size of the second bed layer?
I hope to receive a response!
