SWAT+ Toolbox Output CSV File Empty After Model Run
30-Jyotirmayee Priyadarshini Sahoo
I am currently working on a SWAT+ model for my research project. After successfully setting up the project in SWAT+ Editor and running the model using SWAT+ Toolbox, I am facing an issue with the output files.
The model run completes without any visible error, but when I check the output folder, either no CSV files are generated or the CSV output files are empty.
Project details:
• Software used: SWAT+ Editor and SWAT+ Toolbox
• Watershed area: ~20,800 km²
• Number of HRUs: 148
• Weather data: Precipitation, temperature, etc. imported in SWAT+ format
• Simulation period: 1995-2023
Problem description:
After running the model in SWAT+ Toolbox, the simulation finishes but the output CSV files (such as basin, subbasin, or HRU outputs) are not generated or remain empty.
I would appreciate any suggestions regarding possible reasons for this issue or steps to resolve it.
Thank you for your help.
Best regards,

This is very strange. I suppose you are getting the *.txt output files?
