hello,
i am trying to create a Time-Depth table from IDF table but i dont know how to export the IDF table to the library. kindly i need help for this , it is top urgent.
thanks for your usual support
Hello Mustafa,
Highlight the user defined IDF table, which you wish to export to engineering library, then click on drop-down menu of library and select export to library.
Select the appropriate xml library file i.e. storm even group to which you want the IDF table to be stored.
Please read about constructing a time-depth table from an IDF table/curve, if not already.
How can you construct a time-depth table from an IDF table/curve?

Thanks Sushma for your help.
actually i tried this procedure before but there was an error blow up which drive me to think i am using the wrong procedure, the error message is :
*The wrong type of storm event is specified, For SCS or SBU-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.*
i am running synamic wave for a channel using Explicit (SWMM SOLVER) and SCS CN infiltration method , so why this error is happening while i am using SCS CN and a time-depth curve which i exported exactly as you mentioned above.
thanks and waiting for your feedback.
In addition, i am using Bentley SEWEGEMS V8i (Series 4).
Can you please upload the model files for our review, till that time I am downloading SewerGEMS SS4 version for testing purpose.

Dear Sushma,
i just figure out the reason, the Runoff method for 1 catchment area was set as modified rational not unit hydrograph . i hust update it and it is ok now. many thanks for your following up and help.
