This question is not simple to answer. In general, first you need define what you whant to calibrated, then obtain maximun field information as possible. Search some articles in web and then search in this forum. The International Conference on Computing and Control for the Water Industry, published great articles.

The EPANET user guide for it self, will give to you some clues. For more advanced information I recomend:

Im sure u can widely improve you doubts in 2 or 3 days about this teme.
