Dear all,

Are there any upper and lower limits for the evaporation coefficient value used to determine the evaporation occurring from reservoirs? By default, the evaporation coefficient is set as 0.6.

Regards,
Sreeraj

Hello,

You can find the min and max parameter ranges in the cal_parms.cal file. In your case:
(line 160) evrsv                          res       0.00000       1.0000

Therefore, min = 0, max = 1.0

HTH,
Natalja

I assumed you were working with swat+, not swat2012.
The SWAT2012 has an extensive documentation and I/O manuals, please refer to them.

Hi
I found that the related parameter for the evaporation coefficient is "EVRSV.res," with a range between 0 and 1.
Best;
Aida

Hello everyone,

I am looking for specific data on West Africa, including:

  • Digital Elevation Model (DEM, MNT) with a resolution of 10 to 12.5 meters,
  • Land use data,
  • Soil type data,
  • Slope data.

If you have access to these datasets or know reliable links where I can download them, I would greatly appreciate it if you could share them with me.

Thank you in advance for your help!
