Hi! I’m going to calibrate the model. My question is: Only need modify the Z value for the calibration? I have the observed data in the watershed. So, need I comparing the observed data versus modeling data until to the difference is minor, changing the Z value?
I recommend checking out the information in Appendix 2 of the Annual Water Yield User Guide. It talks about calibration, and references a paper by our hydrologist that describes a sensitivity and calibration process for this model. Hopefully it will be of help.
