CGWAVE. If anyone knows how to solve the following problem: the angle of incident waves for the area in the picture is shown in Fig. Simulations with a monochromatic waves give good results, but when using spectral representation of incident waves theNoname1 copy.bmp results are completely wrong in direction of the incident waves.

Wave breaking is usually defined by the line that represents the relationship wave height/depth of the sea (H/d~0,74). So you can get it by using this formula in data calculator.

I'm not sure that I completely understand the question, but it seems that the angle of 80°(between wave directions 350° and 70°) is too big for semicircural boundary, which is used in CGWAVE. I suspect that the problem in assuming the area. You can send it to me on zeckson@net.hr.

E.g., for transmissible (permeable) breakwaters, there are both a reflective and a transmissive component of wave. When it is buffled breakwater, it is very close to fixed floating dock, so I wonder if there is some experimental data about that....

In CGWAVE, you can assign boundary conditions only as reflection coefficient, but I wonder how close is assigning the floating barrier for the permeable structure, e.g. for baffled breakwater?
Thanks
