Hi,

I am trying to calibrate river discharge, and my model gives the best results with a relative change of -6 for CN2. However, when I check the average CN2 values, they have increased. Even when I check the values by land use, they have also increased.

  
Thanking you,

Asfand

Moreover, when I checked the hru_wb_aa.txt file from the toolbox output files, it varies from the SWAT+ Editor output files, even though I have the same output file selection in both the SWAT+ Editor and the SWAT+ Toolbox. Some of the HRUs have 0 CN values from the toolbox output file.

it seems most people are not setting these settings accordingly and that causes differences between SPE and SPT results. will start inheriting SPE codes.bsn with each new project.
