I have a problem in a practice test that is asking for the outlet control HW depth at the inlet to a 7 x 5' box culvert.
Q=400 cfs
S= 1.5
TW = 3ft
n = 0.012
Is there an outlet control box nomograph?? I'm not seeing one in HDS 5, or any of my references. I'm stuck on solving this.
This isn't the complete problem, so just a little help getting started would be appreciated. Thanks.
