Hi Dr. Tam

I am trying to calibrate my SWAT model using R-SWAT for monthly streamflow data. I was not able to find any instruction on how to set it up in R-SWAT. All the information available is for daily calibration. I would appreciate it if you had information on this matter.

Best,

Dan

Dear Tam,

in the script of userReadSwatOutput.R the FUN= "sum". So, it aggregates the daily values by summing them within a month. Shouldn't that be mean? Observed data is average values to be in the same line as the FLOW_OUT variable in output.rch to perform the calibration.

Thanks for your time,

Best,

Amparo
