Implementing reservois post-watershed delineation step

[Miguel Rodrigues]

Dear community,

I would like to know what is the best approach to implement reservoirs in a calibrated SWAT+ model (after the watershed delinaetion processs), or if there is any approach whatsoever?

Thank you for your attention.

Best regards,
Miguel

Hi Miguel,

This largely depends on your initial setup. In short: if this wasn't considered from the start, it will be extremely difficult to implement later.

You would need to manually edit the objects, their counts, basin areas, routing connectivity, and more. Without in-depth knowledge of the SWAT+ I/O structure, I would say it is impractical. I highly recommend looking over the modeling protocol and implementation handbook, which discusses this exact challenge: https://zenodo.org/records/11232719, https://zenodo.org/records/7463395

Of-course, you can always take on the challenge and try it out :)

Best regards,
Natalja
