Hi all,
I have been trying to include rainfall stations in Weather Data Definitions in SWAT Editor but kept on getting error "Conversion from type 'DBNull to type 'Integer' is not valid".
However, when I put single rainfall station, it is able to run normally. I have checked my data various times for all stations but can't find anywhere that may cause the error.
Just for anyone's reference, I'm including the txt file to help me figure out the problem.
Thanks!
Regards,
