Hello everyone!

I'm trying to calibrate a SWAT + model with SWATPlus_CUP but I'm having some problems. I'm new to SWAT modeling so I ask for your help.

The problem I am encountering is that the NS value does not change no matter how many iterations I make, in addition the "New_pars.txt" is not being generated.

Could someone help me find what I'm doing wrong?

I am attaching the relevant files below, the post-processing image refers to 10 iterations, a test of 200 iterations shows the same results.

Thank you in advance!

you are skipping two years (warm up period) so 87 and 88 are skipped. Your observed data should begin on 89.
Check your start time everywhere, they don't match.

Thank you for replying.

I used observation data from 87 onwards because I considered the simulation starting at 85 (with 2 years of warm up). In the Print file I sent the starting year was 87, I changed it to 85. So, in Print and Time it starts in 85 and in Observed and Extract it start in 87 (due to the warm up).

However, with these years the same problem continues to occur.

Is there anything I'm missing?

In observe and extract file you don't need to include the data for warm up years

Hello Lukwago, thank you for replying!

I did not include warm-up period data in those files. My warm-up period is two years starting at 85, thus 85 and 86.
In the Observed and Extract files I only entered data from 87 onwards.
