Is there a way to implement flow roughness factors or seasonal roughness factors in 2D mesh?

Derek
Hi there,

Perhaps there is a way I didn't figure out...

Is there a way to add flow roughness factors or seasonal roughness factors to a 2D flow area?

Or some way of varying the manning roughness map during the unsteady simulation?

By implementing a shapefile to be utilized as a varying mannings value, you are doing what you are questioning.

You can also override that using the mannings override tool.

But there is no current way to alter mannings values by depth.
