OUTPUT : HY8 FOR CULVERT DESING
OUTPUT : HY8 FOR CULVERT DESING
(OP)
The output of HY8 program (from HYDRAIN family of programs by FHWA)gives you the "type of flow" in the culvert for different discharge values.
For example: 1-S2n, 5-S2n, 1-M2c etc etc.
What is the significance of these short forms. Does anybody has any idea where I can find the description of these short forms used for "type of flow" in the culvert.
I am sure there must be some FHWA publication which explains this...but I couldn't find it!
Please help.

H(2,3) is for horizontal,
M(1,2,3) is for mild slopes (subcritical)
C(1,2,3) is for critical
S(1,2,3) is for steep (supercritical)

I scanned HDS-5 and could not find the charts either. I have seen tables in many hydraulic publications. I found a decent depiction in the following document:

I needed a quick and concise depiction of this for a submittal. This will do.
