REVAP

[Monika]

Hi all

Does the total ET also includes REVAP values in it. If not what is the
role of REVAP in whole water balance.

Thanks and Regards

I don't know for sure, but my guess is that REVAP is already a part of the total ET.  However -- you should check this by setting REVAP to zero, noting the ET, and then compare the results against runs where REVAP is positive.  Let us know what you find.

 I used to track the SWAT2005 code to check the problem.  If I remeber it correctly, the REVAP is not included in ET calculation. Therefore, you have to add the REVAP when calculating actual ET. In my experience, the Evap. from river channel is also not included in the ET values which are calculated from HRUs. Jim's idea is good, you can try and to see if I am right or not.
