Arc Hydro Tool

Question asked by luck.pooja on Mar 1, 2017

I am trying to use Create Drainage Line structure tool in Arc Hydro but it's showing error, even though I've assigned the hydro ID to the stream feature. Hereby I am also linking an attachment of error occurred. My main concern is to condition the dem, also tried assign slope tool but not sure how to decide the high number of starting elevation. Help me with it
