calibration.cal parameter merging issue with distinct land use and HRU conditions

[ken]

Hi SWAT+ Community,

I am having an issue with SWAT+ Toolbox merging parameter entries in calibration.cal.

When defining the same parameter across multiple lines for different HRU sets:

Input calibration.cal:

k 1, 6, 54 

k 4, 7, 16

After loading into SWAT+ Toolbox:

 k 1, 4, 6, 7, 16

 k 1, 4, 6, 7, 16

The GUI automatically merges these separate lines into a single row, combining all HRUs and overwriting the individual settings.

Questions:

1. Is this a known limitation of the SWAT+ Toolbox GUI parser?

2. Is there a specific syntax or setting to keep multi-line parameter definitions separated upon reloading?

Any feedback or suggestions would be greatly appreciated.

Best regards,

Ken
