Manning's coefficient
« on: April 25, 2020, 04:27:25 am »
Is there a way to apply manning's coefficient according to the season of the year. How?

I read something like that in a paper:
A Manning’s roughness coefficient of 0.058 sm1/3 was applied in the
winter, and maximum values of 0.08 sm1/3 and
0.15 sm1/3 were applied in June during high-flow and
low-flow summers, respectively.

Are you referring to roughness in OL or in MIKE 11?
In Release 2019, you can specify a time-varying dfs2 for the OL Mannings coefficient.

Yes, MIKE 11. Thank you for the information!
