Wave+Current interaction

#1 Post by tnmiles » Fri Aug 16, 2013 2:11 pm

Are wave enhanced currents calculated in ROMS by simply forcing with waves, or are there more complicated steps to turn this feature on?

I have a realistic model setup and would like to add in wave forcing for sediment resuspension and transport.

not quite clear what you are asking, but you can think of the waves as working in 3 different regions:

1) surface flux of tke: by activating
** CHARNOK use if Charnok surface roughness from wind stress **
** CRAIG_BANNER use if Craig and Banner wave breaking surface flux **
or
** ZOS_HSIG use if surface roughness from wave amplitude **
** TKE_WAVEDISS use if wave breaking surface flux from wave amplitude **

2) wave driven currents in the water column: by activating
** WEC_MELLOR activate radiation stress terms from Mellor 08. **
** WEC_VF activate wave-current stresses from Uchiyama et al. **
(VF only in COAWST, not Rutgers)

3) wave enhanced bottom roughness: by activating
** MB_BBL use if Meinte Blaas BBL closure **
** MB_CALC_ZNOT use if computing bottom roughness internally **
or
** SG_BBL use if Styles and Glenn (2000) BBL closure **
** SG_CALC_ZNOT use if computing bottom roughness internally **
or
** SSW_BBL use if Sherwood et al. BBL closure **
** SSW_CALC_ZNOT use if computing bottom roughness internally **
and associated other options.

All of those things were essentially what I was getting at. That actually answers my question pretty explicitly, thanks John!
