SSA High Velocitys in pipe.

I am getting really high velocities in SSA through 24" concrete pipe. Maybe a zip of all the run files or something. Anyway, I have tried changing slopes or changing the pipe diameter and have had no sucess. Can anybody offer any insight. The one hydro guy in the office has a program that can only be run through DOS, which hasn't been too helpful for figuring this out.


Any help would be great, still trying to figure out what is going on with it.

Thank you,

Not sure if this will help, but here is a screen capture of the profile. I am also confused about the HGL/EGL, and why it jumps up and down despite the velocity and flow depth not changing.
