Issues with subdaily precipitation and simulation

[Faisal Shovon]

Hello,

I am getting repeated errors while trying to simulate my SWAT plus with sub-daily precipitation and daily data for other climate variables. Could you please look into my weather files and the txtinout folder(compressed) and suggest me any solutions?

Thanks in advance.

Faisal: 

Thank you for your txtinout, I will take a look at this and get back to you.

Thanks a lot Nancy. I have been able to get rid of the error. The cause was I was using time series from 06/01/2021 till 31/05/2025 and put nbyr as 4 in my .cli files in weather variables. Now that I have removed all the timeseries data of 2021 and ran the model from 2022 to 2025 June, the model ran. But I am not getting any precipitation or runoff in my results. I think there is something wrong in my subdaily precipitation format which SWAT+ is not reading. Can you please have a look at this data instead?? Thanks again for your kind help.
