TOPIC: Bijker Formula for Multilayer Bed

Bijker Formula for Multilayer Bed 1 year 4 weeks ago #43514

Dear all,

I am trying to model sediment transport under both waves and tides with a multilayer model. To account for the wave+current effects I use Bijker's formula both for suspended and bed load transport (I tried Soulsby + Van Rijn, however, it seems that SR formula gives too much weight to the waves especially when the waves are higher than 2 m). When I start the simulation I get the following error:
'QSC IS COMING FROM FIRST LAYER OF BEDLOAD PART IN THE CASE OF MULTILAYER OR ACTIVE LAYER, QSC HAVE BEEN TO BE COMPUTED FOR OTHERS LAYER IF THERE IS EROSION OF THE FIRST LAYER IN BED1_SUSPENSION_ERODE'.

Does anybody know what the limitation of Bijker's approach, compared to other formulations, is when I have more than one layers? Is it okay if I just suppress this message by modifying suspension_compute_cae.f?

Kind regards,
Arda
