Good question!
I am at that stage too and hopefully someone will shed some light.

Hi Leah,
The profile lines have to be drawn from left to right in respect of the direction of flow in order to be positive.
If the values are negative, all it means is they have been drawn from right to left but the values should be correct.

Hi,
Yes – you have to create different geometries for every set of changes in Manning’s n values. Once you’ve done that, you then have to create a plan for every geometry.
Then you go on the main RAS screen and hit “Run” -> “run multiple plans..” and you check all the boxes for all the plans you want to run – they will run one after the other so you don’t have to man the station.
