I just want to ask if it is okay to use only two parameters in HEC-HMS? In my study I only used two parameters (Loss- SCS Curve Number, Transform- SCS Unit Hydrograph). I used that parameter base on the data I have. My concern is whether the data (result) I obtained using that two parameters is still good or reliable?

Yes, the data is reliable, but the two parameters operation should be used for Clark unit hydrograph method. I didn't see anything else related to this procedure where you use only two parameters to generate the data. For every other method or operation, two parameters are not enough and you should use the full data range to obtain reliable data.

You can download the following data file for the HEC-HMS software to learn more about it: http://redac.eng.usm.my/EAD/EAD513/HEC-HMS_paper.pdf
