Hi!
Does anyone have more information on this? The manual provides a lack of detail on this. It makes sense that the Hydraulic Radius (R) is computed based on the rating curves between area, depth and hydraulic radius/wetted perimeter at each face. Yet, how is the friction slope computed at the face? Does it use the an average between the two nodes? I know in the 1D steady state computations, there are a couple of different methods to compute the friction slope (e.g. average conveyance). Or does it just use all the values that are already at the face? Or am I not understanding something correctly?
Thank you!
