I am a SWAT model user. I want to ask  if any of you have confronted different modelling results when using different warm-up length? I have found this problem for my case. Would you tell me the potential reasons for this problem I have confronted? Or if you did not note this problem, can you make a test for your case with different warm-up period length such as 1 and 10 years?

Thank you very much for your consideration.
