CN retention adjustment factor for drained areas (SA_fctr)

[Hector Fajardo]

Hi SWAT users,

I would like to know which is the parameter associated with the "retention adjustment factor parameter (SA_fctr)" used when choosing the ICN=2 (CN based on soil moisture but retention is adjusted for mildly-sloped tiled-drained watersheds). 

In the explanation of this method (ICN=2) in Moriasi 2013 (doi:10.2134/jeq2013.01.0018), CN is adjusted with a factor, that in the study is 8 (Page 1702 bellow Eq 2). 

But I'm not able to identify this parameter in the documentation. I have the impression that it could be R2ADJ_BSN.bsn or SSTMAXD_BSN.bsn. Does someone know if it one of these? 

I think that CNCOEF.bsn and SMXCO.bsn are only used with ICN=1 or could it be one of these latest two for ICN=2? 

Best,

Hector
