Dear all,
i am using the Swat+ toolbox with the gwflow module, and after calibration, the "perc" value became very high, even exceeding the "precipitation" value. What could be the cause and how i can fix it?

i appreciate any help, thank you.

Hi Sri,

Can I ask how you developed your SWAT+ model with gwflow? I mean which version of SWAT+ you used? I tried to develop the model with gwflow as groundwater model, but it is not working properly in SWAT+Editor and SWAT+Toolbox.

Kind regards
Saeed
