Dear all,

I try to use the BK to define the river bed materials(sediment distribution), for example in the middle of the river would be fine sand, on downstream would be very coarse sand.

The difination should be like following? is anybody know how to define it ?

for myself, I think it should be defined a initial_river.slf file in the Blue Kenue. But, I don't know what I think is right or not.

And I want to know do they have simple cases about the initial sediment distribution in the examples.

PS:

NBRE DE COURANT is the is the sediment size ??
