In COWAST model, the contribution of waves on the bottom stress can be incorporated by various methods such as SSW_BBL (Madsen, 1994).
Additionally, the dissipation of the wave energy in the BBL results in a bottom stress which can be included by various switches for bottom streaming such as BOTTOM_STREAMING_YU (Kumar et al, 2012).
Since these options parameterise the BBL for the wave current interactions, is there any inter-dependency of these switches?
Also, does WEC_VF just include the conservative forces of waves in ROMS? Because there are other switches available for no-conservative forces (friction, bottom stress)
I will appreciate your reply

Re: Wave induced forces at the bed in COAWST model
there is no inter-dependency between the BBL routines and the new bottom streaming routines. they do not know about each other.
The WEC-VF was implemented to include the conservative and non-conservative forces. Kumar's paper has a lot of information, and lists all the options and the cpp switches. you can also look at some of our test cases like inlet_test, and look at the list in cppdefs:
** Wave effoct on currents (WEC) and shallow water OPTIONS: **
** **
** WET_DRY activate wetting and drying **
** WEC_MELLOR activate radiation stress terms from Mellor 08. **
** WEC_VF activate wave-current stresses from Uchiyama et al. **
** WDISS_THORGUZA activate wave dissipation from Thorton/Guza. **
** WDISS_CHURTHOR activate wave dissipation from Church/Thorton. **
** WDISS_WAVEMOD activate wave dissipation from a wave model **
** ROLLER_SVENDSEN activate wave roller based on Svendsen **
** ROLLER_MONO activate wave roller for monchromatic waves **
** ROLLER_RENIERS activate wave roller based on Reniers **
** BOTTOM_STREAMING activate wave enhanced bottom streaming **
** SURFACE_STREAMING activate wave enhanced surface streaming **
these are all described in kumar's paper.
