Assistance with SWAT+ Calibration

[Keziah Awuah]

Good morning, experts.

I have been calibrating my SWAT+ model using SWAT+ Toolbox, but my NSE value has become stagnant and is no longer improving, despite adjusting parameter ranges and running further iterations.

Could you please advise on what might be causing this and what I can do to improve the calibration?

Thank you.

Let focus on sensitivity parameters related to stream flow since you are calibrating using observed stream flow data.

Therefore, I think you include other parameters like CN2 etc. Try it by modifying  combined parameters rather than alone.

Kind regards,

Seifu

You can try running

the sensitivity analysis with a larger number of parameters to identify which parameters have the greatest influence on the model performance.
