Hello ;
I am new user in the software application, my data observation is 10 years period ,the data was from one (01) gauge station :
1-how to procedure PEST for calibration (validation calibration) . please tell me the correct procedure to do this
2- the the result shows decalage, on what parameter to base to to erase this decalage
3-is it right to proceed calibration without catchment method (without choosing one of the 4 methods)
Thanks in advance for providing this support for the discussions on our manipulation of the Weap software.

Leila,

For help with calibration, please see the WEAP Tutorial chapters for PEST Calibration and for Catchment Calibration at www.weap21.org/tutorial. Alternatively, you can see videos on calibration on our YouTube channel: https://www.youtube.com/watch?v=Notx1vfeRCk.

If you are not choosing a catchment method for your rainfall-runoff calculations, then how are you calculating your inflow? If you are modeling your hydrology using catchments, you would need to first select a method and populate a starting set of expression values for your catchment objects before calibrating.
