Maybe your well past this problem, but if you go back to hydraulics 101, the weir coifficient is some root of 1 over g or something, i will leave that to you to look up. so for a broadcrested wier C-standard = 3.09 and C-metric = 1.704; so C-standard x 0.55 = C-metric. So your coefficient of C-metric = 1.11 is C-standard=2.0. so in your problem, C-metric=0.61whatever is about C = 1.0 in standard, which is extremely low. So C-metric = 1.11 is as conservatively low as you need to go.
Have fun.
