mgt_out fields?

[Camilla Negri]

Dear everyone,

1. Primary Issue Location

• Component: SWAT+ Editor and SWATtunR
• Area of impact: model output/ soft calibration/ data formatting

2. Software Versions

• GIS Interface: * SWAT+ Editor: * SWAT+ Revision: SWAT+ Editor 401, MODULAR Rev 2026.62

3. Project Characteristics

Watershed Details: 2852 ha, 7 subbasins, 800+ HRUs, Located in Ontario, Canada

Modeling Aim: water quality, water balance

4. Description of Issue: I am struggling to understand what the columns of mgt_out are. I have run SWAT but with runswatplus (R function) and the editor, but I cannot tell which columns refer to the crop yields in order to carry out the calibration.

The mgt using runswatplus R function has these headers:

Below I am pasting the header that I think is the one I got from the editor (although the date does not update for some reason) and it's pretty similar

have the headers names changed? The R code example expect headers to be:

variable = 'yld'
variable = 'bioms'

variable = 'phu'

What would these be then? 

Many thanks and best wishes,
