Did you rewrite the mgt files into the txtinout folder, after changing CN2?

Dear Citra


There are many ways for manual calibration. I dont know which method you  have used?
At the beginning i did have the same problem and later I found that I was working in the wrong folder.
I am doing manual calibration from SWAT 2012 folder as per my supervisor advice:

·       Go to the folder where SWAT project file is located > Open .MDB file having same name as the SWAT project > Open data-table of interest (gw, hru, mgt1, rte, sol, sub, etc.)

                           > change values of parameter of interest > Save it

o   To make the change effective: Edit SWAT Input > re-write SWAT files > Select the files that you want to re-write (i.e., the table in which parameters are changed) > Write Files > OK

o   Now SWAT is ready to run with changed parameters.


plz check the range of CN2 max as well as min then go with other parameter like SOLAWC, Lat_time,GW_delay

Thank you
With Warm Regards
