HYDRAFLOW HYDROGRAPH

[tranaT5WL9]

my results for a 100yr Qpk is un-usually TOO high (per my PM) it show triple the Qpk for the 10Yr , any suggestion what might cause this

FIY my PM said it should b around 1.5 times from 10 to 100, instead of 3X 

[fcernst]

I would go punch your PM..

For example, I'm working on a floodplain study for a moderately sized tributary along the Front Range..

and the 10yr = 875 cfs and the 100yr = 2,675 cfs
