HI,
i got this message when i start run the model , however i entered time to depth curve. "The wrong type of storm event is specified. For SCS or SBUH-based hydrology you should use either a time-depth curve or a time-fraction curve. For rational method based catchments, use an I-D-F curve or a, b, n coefficients." Hydrology Validation
Hello Ahmed,
Which numerical solver are you using? Which runoff method is specified ?
Please make sure that all catchments are set to use the desired runoff method e.g unit hydrograph. We have seen a case when the Runoff method for 1 catchment area was set as modified rational this error was generated. Please confirm that in your case.
When calculating a model, the following user notification is generated: "The wrong type of storm event is specified."

the solver is implicit dynamic solver and runoff is SCS,
What type of storm event are you using? If you are using an IDF storm, you would not use a SCS runoff. You would need to use a Time-Depth or Time-Intensity storm event.
