Special Bridge Rating curve

After a long time of absence, I'll try to get back into HEC-RAS/UNET
.... I've got a section working, which includes one bridge (simple with a single opening in the middle). I have used the special bridge and wanted to look at the rating curves for this bridge. The manual states that actually three different rating curves are produced, can I look at these rating curves individually? The program seems to print only 'one' interpolated and smoothed one.

Thanks,

Florian:

When you say "Special Bridge" it makes me think that you are using HEC-2, because HEC-RAS does not do the HEC-2 special bridge scheme. The geometry must be edited if imported from HEC-2 to HEC-RAS. Also, I looked at the manuals and I didn't see any discussion of 3 rating curves. Could you supply a page number in the particular manual you saw this in?
