How to callibrate the parameters

[Aditya Sigdel]

Warm greetings to all of you, I am using swat-cup for the first time and I have a little problem understanding how to iterate the parameters if there is a standard approach to be followed I would like to know that, because iterating from different approaches ( I tried only one parameter at a time, only the sensitive parameters at a time, only the driving i.e. parameters that introduce water to the system, and even all parameters at once ) but the range values of parameters obtained was significantly different in each of those processes. I am a little lost on how it should be actually done.
