Does anyone know which value of Shape Factor SSA uses? In my office, before I joined, Hydraflow was being used where Shape Factor was one of the input values. When I used SSA for my project, it didn't ask for Shape Factor value. So I am not sure if it assumes a particular value.
Thanks,

Review Dimenionless Unit Hydrograph. The Standard 484 is pretty typical, but there are other pre-defined values available
I am not able to find out which shape factor the program is using. Where do you find that information? Can it be changed/selected?

Change the Hydrology Engine to TR-20 and review the Dimensionless Unit Hydrograph.
The Standard 484 Shape factor is the SCS Unit Hydrograph.
Thank you.
It would be nice if the shape factor input was placed with the rainfall selection criteria rather than by tself.
