I'm currently working with the SWAT model and analyzing the reservoir output file . I want to better understand how the outflow values reported in this file are computed ?

Specifically, I'm looking for clarification on the following:

  • What does the outflow column represent in output .adb file? Is it regulated flow, spillover, or a combination of both?

  • How does SWAT calculate outflow based on the reservoir parameters (e.g., RES_K, RES_PVOL, RES_EVOL, RES_NSED, etc.)?

  • Is there a way to differentiate between release for demand (e.g., irrigation) vs excess outflow due to overflow?
