Request for Guidance on Reducing High Flow Peaks During SWAT+ Calibration

[mabel mary]

Dear all, 

I am currently working on the calibration of a SWAT+ model and have encountered an issue where the simulated peak flows are significantly higher than the observed data. The magnitude of the peak flows is consistently overestimated by the model.  I would appreciate any guidance on which parameters are most effective in reducing these high flow peaks during calibration. Thanks.

Best Regards,

Rose Mary
