Dear SWAT+ Community,

I am currently working on the grid model of SWAT+ and have incorporated over 1500 reservoirs and playas into my simulation. As the playas generate HRUs, I need to route water from these HRUs either to other HRUs or to downstream links. To achieve this, I need to make several modifications in the .con file, specifically to add outflows manually. However, I have been unable to locate the specific file or columns that allow me to modify the outflow object, receiving object, and Type of hydrograph that is sent to the receiving object etc. for the HRU routing.

I have already checked the HRU.con file but could not find the relevant columns related to these parameters. Could anyone guide me to the correct file or provide insights on where and how to make these changes?

Additionally, when I run the model through the executable command line, it starts but stops automatically without providing any error message. Any suggestions or troubleshooting tips for this issue would be greatly appreciated.

Thank you for your help!

Best regards,

Swetasree
