Hi,

I am modelling a drainage network with SWMM 5.0 and the peak flow values simulated are about 6 times lower than the observed ones.

To test what could be wrong, I changed the Horton parameters drastically, but the hydrograph didn't change at all, even when I set the parameters with 0.

Does anyone know how to help me?

Thanks,
