how do you generate a hydrograph?
(OP)
Hi,
I was wondering what program do you use to generate a hydrograph. I just saw a hydrology report done by someone else and the person used Hydaflow Hydrographs Extension to design a detention basin. But the hydrgraph was manually input, so the engineer did not use Hydraflow to create the hydrograph. The hydrograph looked like a smooth bell curve. I think Hydraflow generates the triangular one. We use Modified Rational Method here in Southern California for smaller projects.
Do you have any idea which program was used, and where can I get it?
Thank you in advance!

Your local agency may have a specific Unit Hydrograph that is required for your location. You may want to refer to the original drainage report or standard drainage manual. I know that our state, county and city agencies all have unit hydrographs.

That should explain where the "bell shaped curve" hydrographs come from.

That software is basic and right from the horse's mouth. After you understand how that stuff works, then move on to HEC-HMS or something similar.
