Was wondering can we have depth varying roughness in RAS Mapper? I have checked the manuals and RAS mapper 6.4 cell property table still shows a constant value for all depths. but then i come across various youtube videos where they say that you can but then, i could not find anything there as well. Was wondering am i missing something OR is there a way to introduce depth varying roughness landcover layer that can actually be used in RAS computations?
I don’t know if this can help, but in RAS Mapper, in the 2D Flow Area Editor there is a “Spatially Varied Mannin’s on Faces”, which produces variation in the Manning coefficient according to different depths.
