HEC-HMS vs PondPack Difference in Peak Flow
HEC-HMS vs PondPack Difference in Peak Flow
(OP)
I am recreating a model I had in HEC-HMS in PondPack (SCS Unit Hydrograph, CN), the runoff volumes are identical between the two, however the peak flows vary up to 4.3%, is this normal? Or should I be getting closer results between both models. I tried using the same Time-Interval/Output Increment on both models but I keep getting these differences.
Any help will be appreciated.
