wave breaking issue

[jurnal Gugum]

Dear all, 

I am trying to simulate wave-induced currents over a peculiar submerged bar by using regular wave. However, a comparison with experimental data showed that the model produce breaking location 4 m away against the experiment. At the moment I am using viscosity breaking scheme with Cbrk: 0.01 and Cbrk2: 0.2. Default values for both Cbrk1 and Cbrk2 produced more onshore breaking location. I attached the figure of Hs and input file for the sake of completion. Any helps and suggestion to tune in the breaking coefficient highly appreciated. 

Many regards,

Gugum
